I'm trying to list all the properties associated with a given calendar appointment, but I can't figure out if there's a way to do it without loading each property individually. Based on some of the code I've seen online, I know I can do something like the following:
/// <summary>
/// List all the properties of an appointment
/// </summary>
public void listProps()
{
Folder myCalendar = Folder.Bind(service, WellKnownFolderName.Calendar);
ItemView view = new ItemView(10);
FindItemsResults<Item> findResults;
do
{
findResults = myCalendar.FindItems(new SearchFilter.IsEqualTo(ItemSchema.ExtendedProperties, MyPropertySetId), view);
service.LoadPropertiesForItems(findResults, new PropertySet(ItemSchema.Subject, ItemSchema.Body));
foreach (Item item in findResults)
{
Console.WriteLine(item.Subject);
Console.WriteLine(item.Body);
}
if (findResults.NextPageOffset.HasValue)
{
view.Offset = findResults.NextPageOffset.Value;
}
} while (findResults.MoreAvailable);
}
However, what I'm really looking for there in the middle is something like this pseudo code:
service.LoadPropertiesForItems(findResults, new PropertySet(*.*));
foreach (Item item in findResults)
{
Console.WriteLine(property)
}
Is this possible?
Thanks!
No, it is not possible.
You can use predefined property sets like: PropertySet.FirstClassProperties to get the known set of properties.
Getting extended properties this way is not supported at all. You have to specify explicitly which extended properties you want to access. For example:
ItemView view = new ItemView(10);
ExtendedPropertyDefinition extendedPropertyDefinition =
new ExtendedPropertyDefinition("Expiration Date", MapiPropertyType.String);
view.PropertySet =
new PropertySet(BasePropertySet.FirstClassProperties, ItemSchema.Subject,extendedPropertyDefinition);

I saw a related question:
Sitecore Glass Mapper always null
But unfortunately it does not give a solution for my case.
Here goes a code snippet:
var db = Factory.GetDatabase("master");
var context = new SitecoreContext();
// the ID of Needed item
var g = new Guid("{F21C04FE-8826-41AB-9F3C-F7BDF5B35C76}");
// just to test if it's possible to fetch item using db.GetItem
var i = db.GetItem(new ID(g), Language.Current, Sitecore.Data.Version.Latest);
// Grab item
var t = context.GetItem<Article>(g);
In the code above:
i is not null
t is null
Article is the simple class like:
[SitecoreType(TemplateId = "{4C4EC1DA-EB77-4001-A7F9-E4C2F61A9BE9}")]
public class Article
{
[SitecoreField(FieldName = "Title")]
public string Title { get; set; }
}
There are only one language installed in Sitecore - en, it has been specified in the web.config in the items as well.
Also I have added GlassMapperSc.Start(); to Application_Start in the Global.asax.cs and added my assembly to the list of included assemblies via var attributes = new AttributeConfigurationLoader(new[] { "Assembly.Name" }); and I succeeded to find my class in the SitecoreContext mappings.
It does not looks like a language issue, as stated in the link provided in the very beginning. And I'm struggling with it already for a pretty long time, but no luck...
Thank You!
I just noticed that you are using master db for the Sitecore DB and SitecoreContext for Glass.
The SitecoreContext class will use the database that is defined by the Sitecore.Context.Database property at runtime. This probably means that it is using the web database.
Can you check that you have published the item to the web database or instead using:
var context = new SitecoreService("master");
I'm using Ektron CMS version 9.0
I have smart form content which is allocated to taxonomies e.g. I might have five smart form content items (all of same) type allocated to a taxonomy, and another three to a different taxonomy:
I need to get all content of a smart form type from a taxonomy:
public IEnumerable<T> GetListOfSmartFormFromTaxonomy<T>(long taxonomyId, bool isRecursive) where T : class
{
// TODO
}
What I have working, based on links below, is this:
public IEnumerable<TaxonomyItemData> GetListOfSmartFormFromTaxonomy(long taxonomyId)
{
TaxonomyItemCriteria criteria = new TaxonomyItemCriteria();
criteria.AddFilter(TaxonomyItemProperty.TaxonomyId, CriteriaFilterOperator.EqualTo, taxonomyId);
TaxonomyItemManager taxonomyItemManager = new TaxonomyItemManager();
List<TaxonomyItemData> taxonomyItemList = taxonomyItemManager.GetList(criteria);
return taxonomyItemList;
}
But this just gets the item's titles and ids, not the smart form data itself.
As an Ektron newbie, I don't know how to get all the items of one Smart Form type using only one call (instead of looping through each item and fetching it by ID which is not efficient)
What have I missed? I am working on this actively today and will post my findings here.
References used so far:
http://reference.ektron.com/developer/framework/Organization/TaxonomyItemManager/GetList.asp
Ektron taxonomy and library items (in v9)
EDIT
Posted my just-got-it-working solution below as an fyi and awarded closest answer as accepted. Thanks everyone for your help. Please chime in with any improvements ;)
I'd recommend using the ContentTaxonomyCriteria with the ContentManager.
long smartFormId = 42;
long taxonomyId = 127;
bool isRecursive = true;
var cm = new ContentManager();
var taxonomyCriteria = new ContentTaxonomyCriteria();
taxonomyCriteria.AddFilter(ContentProperty.XmlConfigurationId, CriteriaFilterOperator.EqualTo, smartFormId);
taxonomyCriteria.AddFilter(taxonomyId, isRecursive);
var content = cm.GetList(taxonomyCriteria);
UPDATE
The ContentData object has a property called XmlConfiguration. When the content is based on a smartform, this property will be non-null and have a positive (non-zero) Id: content[0].XmlConfiguration.Id for example.
I often add an Extension Method to my code that will tell me whether a given ContentData is based on a smart form:
public static class ContentDataExtensions
{
public static bool IsSmartFormContent(this ContentData content)
{
return content != null && content.XmlConfiguration != null && content.XmlConfiguration.Id > 0;
}
}
That way I can take a content (or list of content) and check it very quickly in code to see if it's based on a smartform or not:
foreach (var contentData in contentList)
{
if (contentData.IsSmartFormContent())
{
// Do smart-form stuff here...
}
}
Of course, if your content is coming from the framework api and you used a criteria object that is selecting based on a specific XmlConfigurationId, then in theory you wouldn't have to use that, but it still comes in handy quite often.
I'm not quite sure I understand your organizational structure, but you do have the ability to do your own sub clauses that select directly against the database.
In this case I wouldn't use the TaxonomyItemManager, I would use the ContentManager with a special criteria:
ContentManager cApi = new ContentManager();
var criteria = new ContentCriteria();
criteria.AddFilter(ContentProperty.Id, CriteriaFilterOperator.InSubClause, "select taxonomy_item_id where taxonomy_id = " + taxonomyId);
criteria.AddFilter(ContentProperty.XmlConfigurationId, CriteriaFilterOperator.EqualTo, smartformTypeId);
var yourContent = cApi.GetList(criteria);
That should do what you're asking for (grab the content specifically that is a member of a Taxonomy while only being of a specific SmartForm config). It's worth noting you don't need the second criteria piece (XmlConfigurationId) if your Taxonomy only contains that XmlConfiguration.
For Information, this is what I came up with. Noted Brian Oliver's comment on List but using patterns from other devs, can refactor later.
To clarify, we are creating classes from the XSDs generated from the smart forms, so have smart form types to play with. Your use may be simpler that ours.
public IEnumerable<T> GetListOfSmartFormFromTaxonomy<T>(long taxonomyId, bool isRecursive = false) where T : class
{
long smartFormId = GetSmartFormIdFromType(typeof(T));
// checks here for smartformid=0
ContentManager contentManager = new ContentManager();
ContentTaxonomyCriteria criteria = new ContentTaxonomyCriteria();
// Smart Form Type
criteria.AddFilter(ContentProperty.XmlConfigurationId, CriteriaFilterOperator.EqualTo, smartFormId);
// Taxonomy
criteria.AddFilter(taxonomyId, isRecursive);
List<ContentData> contentDataList = contentManager.GetList(criteria);
IEnumerable<T> smartFormList = ConvertToSmartFormList<T>(pressReleaseDataList);
return smartFormList;
}
private IEnumerable<T> ConvertToSmartFormList<T>(List<ContentData> contentDataList) where T : class
{
List<T> smartFormList = new List<T>();
if (contentDataList != null && contentDataList.Count > 0)
{
foreach (ContentData contentData in contentDataList)
{
if (contentData.IsSmartFormContent())
{
T smartForm = GetDeserializedContent<T>(contentData.Html);
if (smartForm != null)
{
PropertyInfo property = smartForm.GetType().GetProperty("ContentId");
if (property != null)
{
property.SetValue(smartForm, contentData.Id, null);
}
smartFormList.Add(smartForm);
}
}
}
}
return smartFormList;
}
private long GetSmartFormIdFromType(Type smartFormType)
{
SmartFormConfigurationManager manager = new SmartFormConfigurationManager();
SmartFormConfigurationCriteria criteria = new SmartFormConfigurationCriteria();
// Note: Smart Form Title must match the type's name, i.e. no spaces, for this to work
criteria.AddFilter(SmartFormConfigurationProperty.Title, CriteriaFilterOperator.EqualTo, smartFormType.Name);
List<SmartFormConfigurationData> configurationData = manager.GetList(criteria);
if (configurationData == null || configurationData.Count == 0)
{
return 0;
}
return configurationData.First().Id;
}
I have the following data model:
I am writing a WCF service that needs to support adding new Report:
public bool CreateNewReport(Report report)
{
MyEntities context = new MyEntities();
context.AddToReports(Report);
context.SaveChanges();
}
So my method gets a report object that was made on the client and adds it to the database throught the data context. (all of the members are included in the DataContract)
My question is regarding navigation properties.
Do the client also needs to create a user object and put it in the new report object before sending it ?
What is the best way to approach this ? one way i think of is adding a UserId field in the ReportEntity
when a new report is inserted, how do i update the UserEntity Report nav property that with the new Report ?
Thanks.
If you import your database, generate navigation properties (the properties in your picture) AND foreign id properties (then you have for example an User and UserID property in your report class). This way you can set the UserID in your client and send it to the server and add it with AddToReports... If you send the whole user object you have to attach it to the entity context otherwise the user will be created once again...
Attach the referenced user: (but it's better to send the user only by id)
public bool CreateNewReport(Report report)
{
using (MyEntities context = new MyEntities())
{
context.AddToReports(Report);
context.Users.Attach(report.User);
context.SaveChanges();
}
}
To change the report of a user:
public bool ChangeUserToNewReport(int userid, Report newReport)
{
using (MyEntities context = new MyEntities())
{
var user = context.Users.Single(u => u.ID = userid);
user.Report = newReport;
context.SaveChanges();
}
}
For an existing report:
public bool ChangeUserReport(int userid, Report existingReport)
{
using (MyEntities context = new MyEntities())
{
context.Reports.Attach(existingReport);
var user = context.Users.Single(u => u.ID = userid);
user.Report = existingReport;
context.SaveChanges();
}
}
This is a sample how your model should look like. Double click on the association line to open the dialog. You can see that the Person and PersonID properties are the same. If you create your model like this, VS should generate the correct SQL.
I've got a Silverlight 4 RIA Services (SP1) app using Entity Frameworks 4 CTP5. I can databind a grid or listbox to the IEnumerable loaded by the domain context and it shows data from the server. Great.
Now I want to create a new instance of MyEntity and add it to the client-side data so that the user can see the newly added entity. MyEntity is a true entity descendant, not a POCO.
The only Add method I can find is domainContext.EntityContainer.GetEntitySet<MyEntity>().Add(newobj)
This does add the new entity to the domain context, and the domainContext.HasChanges does become true, but the new entity doesn't show up in the databound controls.
How do I get the new entity to show up in the databound controls prior to SubmitChanges?
(Probably related to this SO question from years ago that never got an answer)
Here's the server side declarations of the domain service, per requests:
[EnableClientAccess()]
public class MyDomainService : LinqToEntitiesDomainService<MyObjectContext>
{
protected override MyObjectContext CreateObjectContext()
{
return new MyObjectContext();
}
public IQueryable<MyEntity> GetMyEntities()
{
return this.ObjectContext.MyEntities;
}
public void InsertMyEntity(MyEntity MyEntity)
{
// ...
}
public void UpdateMyEntity(MyEntity currentMyEntity)
{
// ...
}
public void DeleteMyEntity(MyEntity MyEntity)
{
// ...
}
}
I've figured this out with a combination of my own trial and error and hints provided by some of the other responses to this question.
The key point I was missing was that it's not enough for the ViewModel to keep track of the DomainContext and hand out query results to the View for databinding. The ViewModel also has to capture and retain the query results if you want entity adds and deletes performed by the ViewModel to appear in the UI before DomainContext.SubmitChanges(). The ViewModel has to apply those adds to the collection view of the query results.
The ViewModel collection property for View databinding. In this case I'm using the Telerik QueryableDomainServiceCollectionView, but other collection views can be used:
public IEnumerable<MyEntity> MyEntities
{
get
{
if (this.view == null)
{
DomainContextNeeded();
}
return this.view;
}
}
private void DomainContextNeeded()
{
this.context = new MyDomainContext();
var q = context.GetMyEntitiesQuery();
this.view = new Telerik.Windows.Data.QueryableDomainServiceCollectionView<MyEntity>(context, q);
this.view.Load();
}
The ViewModel function that adds a new entity for the UI to display:
public void AddNewMyEntity(object selectedNode)
{
var ent = new MyEntity() { DisplayName = "New Entity" };
if (selectedNode == null)
{
this.view.AddNew(ent);
}
else if (selectedNode is MyEntity)
{
((MyEntity)selectedNode).Children.Add(ent);
}
}
Other responses mentioned ObservableCollection. The query results and the collection view may not return instances of ObservableCollection. They could be just IEnumerables. What is critical is that they implement INotifyCollectionChanged and IEditableCollectionView.
Thanks to those who contributed responses. I've +1'd each response that was helpful, but since none directly solved my problem I couldn't justify marking any as the definitive answer.
Your domainContext will have a property domainContext.MyEntities. Does it not show up in there when you add it?
Bind to that collection or watch that collection for changes.
domainContext.MyEntities.PropertyChanged += MyEventHandler;
I assume you bind your control to the IEnumerable which is provided by LoadOperation<TEntity>.Entities. In that case your binding source is not the DomainContext.GetEntitySet<MyEntity>().
DomainContext.GetEntitySet<MyEntity>() holds all your currently tracked instances of MyEntity, including the one you add with .Add().
LoadOperation<TEntity>.Entities only contains the instances of MyEntity that were actually loaded by your last LoadOperation/Query.
You have two options: Either add the new entity to the ItemsSource-collection for your control (I recommend that) or rebuild the collection with the contents of DomainContext.GetEntitySet<MyEntity>(). That may contain other elements that you have not cleared out before, though.
I am having a minor problem with WCF service proxies where the message contains List<string> as a parameter.
I am using the 'Add Service reference' in Visual Studio to generate a reference to my service.
// portion of my web service message
public List<SubscribeInfo> Subscribe { get; set; }
public List<string> Unsubscribe { get; set; }
These are the generated properties on my MsgIn for one of my web methods.
You can see it used ArrayOfString when I am using List<string>, and the other takes List<SubscribeInfo> - which matches my original C# object above.
[System.Runtime.Serialization.DataMemberAttribute(EmitDefaultValue=false)]
public System.Collections.Generic.List<DataAccess.MailingListWSReference.SubscribeInfo> Subscribe {
get {
return this.SubscribeField;
}
set {
if ((object.ReferenceEquals(this.SubscribeField, value) != true)) {
this.SubscribeField = value;
this.RaisePropertyChanged("Subscribe");
}
}
}
[System.Runtime.Serialization.DataMemberAttribute(EmitDefaultValue=false)]
publicDataAccess.MailingListWSReference.ArrayOfString Unsubscribe {
get {
return this.UnsubscribeField;
}
set {
if ((object.ReferenceEquals(this.UnsubscribeField, value) != true)) {
this.UnsubscribeField = value;
this.RaisePropertyChanged("Unsubscribe");
}
}
}
The ArrayOfString class generated looks like this. This is a class generated in my code - its not a .NET class. It actually generated me a class that inherits from List, but didn't have the 'decency' to create me any constructors.
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "3.0.0.0")]
[System.Runtime.Serialization.CollectionDataContractAttribute(Name="ArrayOfString", Namespace="http://www.example.com/", ItemName="string")]
[System.SerializableAttribute()]
public class ArrayOfString : System.Collections.Generic.List<string> {
}
The problem is that I often create my message like this :
client.UpdateMailingList(new UpdateMailingListMsgIn()
{
Email = model.Email,
Name = model.Name,
Source = Request.Url.ToString(),
Subscribe = subscribeTo.ToList(),
Unsubscribe = unsubscribeFrom.ToList()
});
I really like the clean look this gives me.
Now for the actual problem :
I cant assign a List<string> to the Unsubscribe property which is an ArrayOfString - even though it inherits from List. In fact I cant seem to find ANY way to assign it without extra statements.
I've tried the following :
new ArrayOfString(unsubscribeFrom.ToList()) - this constructor doesn't exist :-(
changing the type of the array used by the code generator - doesn't work - it always gives me ArrayOfString (!?)
try to cast List<string> to ArrayOfString - fails with 'unable to cast', even though it compiles just fine
create new ArrayOfString() and then AddRange(unsubscribeFrom.ToList()) - works, but I cant do it all in one statement
create a conversion function ToArrayOfString(List<string>), which works but isn't as clean as I want.
Its only doing this for string, which is annoying.
Am i missing something? Is there a way to tell it not to generate ArrayOfString - or some other trick to assign it ?
Any .NET object that implements a method named "Add" can be initialized just like arrays or dictionaries.
As ArrayOfString does implement an "Add" method, you can initialize it like this:
var a = new ArrayOfString { "string one", "string two" };
But, if you really want to initialize it based on another collection, you can write a extension method for that:
public static class U
{
public static T To<T>(this IEnumerable<string> strings)
where T : IList<string>, new()
{
var newList = new T();
foreach (var s in strings)
newList.Add(s);
return newList;
}
}
Usage:
client.UpdateMailingList(new UpdateMailingListMsgIn()
{
Email = model.Email,
Name = model.Name,
Source = Request.Url.ToString(),
Subscribe = subscribeTo.ToList(),
Unsubscribe = unsubscribeFrom.To<ArrayOfString>()
});
I prefer not to return generic types across a service boundary in the first place. Instead return Unsubscribe as a string[], and SubscriptionInfo as SubscriptionInfo[]. If necessary, an array can easily be converted to a generic list on the client, as follows:
Unsubscribe = new List<string>(unsubscribeFrom);
Subscribe = new List<SubscriptionInfo>(subscribeTo);
Too late but can help people in the future...
Use the svcutil and explicitly inform the command line util that you want the proxy class to be serialized by the XmlSerializer and not the DataContractSerializer (default). Here's the sample:
svcutil /out:c:\Path\Proxy.cs /config:c:\Path\Proxy.config /async /serializer:XmlSerializer /namespace:*,YourNamespace http://www.domain.com/service/serviceURL.asmx
Note that the web service is an ASP.NET web service ok?!
If you are using VS 2008 to consume service then there is an easy solution.
Click on the "Advanced..." button on the proxy dialog that is displayed when you add a Service Reference. In the Collection Type drop down you can select System.Generic.List. The methods returning List should now work properly.
(Hope this is what you were asking for, I'm a little tired and the question was a tad difficult for me to read.)
