I have a custom list in my sharepoint 2010 site. I want to set a limit to the list, that after reaching the limit(say 10 items), no one can add any more items to that list.
how it can be done.. please tell me how to do it.
Thanks in advance.
I dont think this can be achieve OOTB features of sharepoint .
But i may be possible with the use of some programming
You can use event receiver to achieve this.
When an Item is adding in the list check foe the count of a list
if count is 10 then cancel the event.
public override void ItemAdding(SPItemEventProperties properties)
{
SPWeb web = properties.OpenWeb();
SPList list = web.Lists[properties.ListId];
if (list.ItemCount == 10)
{
properties.Cancel = true;
}
else
{
base.ItemAdding(properties);
}
}
Hope this helps

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 am trying to create a few lists using features so that these custom lists are created automatically as soon as the feature is activated on a team site. The feature is scoped at a site level.
Is it possible to check weather a list already exists in a site collection before adding a new list using feature? I tried to do this check on feature activated event which gave me error saying list with same name already exists. Any help will be greatly appreciated. Thanks
public static class SPWebHelper
{
public static bool IsListExistByTitle(this SPWeb web, string title)
{
return web.Lists.Cast<SPList>().FirstOrDefault(
list => list.Title == title) != null;
}
public static bool IsListExistByInternalName(this SPWeb web, string internalName)
{
return web.Lists.Cast<SPList>().FirstOrDefault(
list => list.RootFolder.Name == internalName)!=null;
}
}
call extension function
bool existlist = SPContext.Current.Web.IsListExistByTitle("YourListTitle");
Here's what I'm trying to accomplish - to change a draft's property, which through the OM appear as read-only. Is there a way or my search is futile and I'll end up deleting and creating another item?
Thanks in advance!
using (SPSite site = new SPSite("http://server/sites/blank2"))
{
foreach (SPListItemVersion v in site.RootWeb.Lists["Pages"].Items[0].Versions)
{
if (v.Level == SPFileLevel.Draft)
{
// CHANGE PROPERTY HERE
// NOT POSSIBLE TO DO e.g., v["Title"] = "blah", it's read-only
As far as I can tell the SPListItemVersion object only has Get properties. http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.splistitemversion_properties.aspx
I have a problem retrieving items from a fairly large list. I can quickly and easily retrieve items from a small list with more or less 50 items, but when I try to retrieve items from a list containing more or less 4600 items, the sqlsever.exe process spikes for the duration of the request, but the items are never retrieved. If have set up the web applications throttling settings, so it can’t be that which is causing the problem. Here is the code that I originally used to retrieve the items. There is really nothing special to it.
using (SPSite site = new SPSite(siteUrl))
{
using (SPWeb web = site.OpenWeb())
{
SPList list = web.Lists[uid.ToString()];
SPListItemCollection itemCollection = list.Items;
foreach (SPListItem i in itemCollection) //This is where the code stops responding
{
//Use list items
}
}
}
After that didn’t work, I tried a couple of other methods to retrieve the items from the list. Here is the code:
SPList list = web.Lists[uid.ToString()];
SPQuery query = new SPQuery();
query.Query = "";
query.QueryThrottleMode = SPQueryThrottleOption.Override;
SPListItemCollection itemCollection = list.GetItems(query);
//The code stops here
//I added this part for interest sake, i wanted to if it was the looping that caused the problem
//It seems the when you try to access properties of the item collection that the problem occurs
int itemCount = itemCollection.Count;
foreach (SPListItem i in itemCollection)
{
//Use list items
}
I also tried:
SPList list = web.Lists[uid.ToString()];
SPListItemCollectionPosition pos;
DataTable dt = list.GetDataTable(new SPQuery(), SPListGetDataTableOptions.None, out pos); //The code stops responding here
foreach (DataRow i in dt.Rows)
{
//Use data rows
}
Does anyone know what could be causing this problem?
Thank you in advance!
After a very long struggle we found a solution.
We found this post:
http://trycatch.be/blogs/tom/archive/2009/04/22/never-turn-off-quot-auto-create-amp-auto-update-statistics-quot.aspx
We tested it and it worked!!!
So all we had to do was switch "Auto create statistics" and "Auto update statistics" to true, and to problem was solved
Thanks for all the replys
You'll kill your server if you always try to retrieve all items either through list.Items, list.GetItems(query) (with an empty query).
You need to define a relevant query and specify the amount of results you want to retrieve through the RowLimit property of your SPQuery
SPQuery query = new SPQuery();
query.Query = "<OrderBy><FieldRef Name='Title' /></OrderBy>"; // any relevant query here
query.RowLimit = 50;
Failing to do so will load all the items in memory prior to any other operation. You will probably kill your application pool available memory or your sql server memory when it will try to load all these data !
Hope that helped.
Try to get data using CAML query.
Once you have data you can put that in SPQuery.
Try to load the items not all at the same time. You can load them bulk wise (page wise) with the help of SPQuery.ListItemCollectionPosition (http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.spquery.listitemcollectionposition.aspx).
This is not a question but my answer to a problem I could not find a solution to on the internet.
I had a problem clearing the SearchText in an MVVM Silverlight application. I could clear clear the SelectedItem and Text but the SearchText was left behind. It is read only and cannot be changed by binding.
Example: AutoCompleteBox with a list of Countries. When the user wants to enter Australia they enter 'au' at this point the list appers with Austria and Australia. The user can then select Australia and move on. At the end of editing they click on a 'Save' button. At this point it is likely that you would want to clear the data forn for entering new data.
Even if you have bindings to the SelectedItem and the Text properties and you set them to 'null' and string.Empty respectively the SearchText property remains and the AutoCompleteBox will not clear but will contain 'au'.
I posted about this all over the internet but could get no answer on the control itself and so I came at it from a different angle which may help someone who ends up frustrated like me.
I am using a Silverlight Navigation template application which uses a NavigationFrame in which to load Silverlight pages. I noticed that if I navigated to another page and returned to my data form the SearchText was cleared. Any values that were bound to properties remained valid, just the SearchText had cleared on all AutoCompleteBoxes. I therefore used the PageConductor method of injecting the NavigationFrame into the ViewModel where I could call the refresh method. I got this method from John Papa's example from the Silverlight Firestarter event , I simply added a Refresh method to the IPageConductor interface so I am now able to call 'PageConductor.Refresh()' which is like reloading the page. I hope this helps someone out there.
var t = ProductCombo.ItemsSource;
ProductCombo.ItemsSource = null;
ProductCombo.Text = string.Empty;
ProductCombo.SelectedValue = null;
//ProductCombo.Text = string.Empty;
ProductCombo.ItemsSource = t;
Try this please.it worked for me
You must clear the property bindeaded to Text inside set part of SelectedItem Binded property, like this:
public string AnalisisText
{
get { return _analisisText; }
set
{
if (_analisisText == value)
{
return;
}
_analisisText = value;
RaisePropertyChanged(AnalisisTextPropertyName);
}
}
public DatosAutoCompletaPedidosDetalleViewDTO AnalisisSelect
{
get { return _analisisSelect; }
set
{
if (_analisisSelect == value)
{
return;
}
_analisisSelect = value;
if (_analisisSelect == null) AnalisisText = "";
RaisePropertyChanged(AnalisisSelectPropertyName);
}
}
So, when you set null to property SelectedItem , the other property will set to "".
The easiest way I've found is to extend the AutoCompleteBox:
public class AutoCompleteBoxClear : AutoCompleteBox
{
public AutoCompleteBoxClear()
{
DataContextChanged += (o, e) =>
{
if (SelectedItem == null)
Text = string.Empty;
};
}
}
Now use your new AutoCompleteBoxClear control in your XAML.
This clears the text only when autocompletebox datacontext changes to null (ie the user clicks add in the dataform.)
Note: I think DataContextChanged is available only in Silverlight 5, but I'd guess that anyone still using Silverlight these days would likely have upgraded by now...
var t = ProductCombo.ItemsSource;
ProductCombo.ItemsSource = null;
ProductCombo.Text = string.Empty;
ProductCombo.SelectedValue = null;
//ProductCombo.Text = string.Empty;
ProductCombo.ItemsSource = t;
Unfotunately this is code-behind and I needed an MVVM solution.
I recently had the same problem with my WPF app. I found out that the solution is not to set the object bound to SelectedItem to null, but to its default value. Took me a while to figure this out. So in your example, it would not be SelectedCountry = null, but SelectedCountry = new SelectedCountry(). In this case the SearchText is cleared also. Check my SO post regarding this matter: Autocompletebox doesn't clear keyboard strokes.
Sure SearchText property is read-only, but we can get the child component of AutoCompleteBox:
var searchText = autoCompBox.GetChildByType<TextBox>(item => item.Name == "Text");
And now we can reset SearchText via Text property of TextBox-component:
if (searchText != null) searchText.Text = string.Empty;
In C# 6.0 it is more laconically:
autoCompBox.GetChildByType<TextBox>(item => item.Name == "Text")?.Text = string.Empty;
