I am working on a sample project as my learning process. So in my project I am having an IsActive field which is a radio button . It will give either true or false. So if Is Active is False I have to make some fields mandatory like Reason,Remarks etc.I tried so many things but nothing is working for me.I am not understanding what all things I have to modify and also the places where I should modify
. I am working on MVC and consider my knowledge is low. And I have to do it as model validation so custom data annotation is what I want. Any help will be appreciated.
I created a cs file like
public class IsActiveTrue : ValidationAttribute
{
public override bool IsValid(object value)
{
var item = (Pen)value;
if (item.IsActive == false)
{
if (item.ReportNo == null || item.Reason == null || item.Remarks == null)
{
return false;
}
else
{
return true;
}
}
else
{
return true;
}
}
}
and in model
[IsActiveTrue(ErrorMessageResourceType = typeof(Resources.Resource), ErrorMessageResourceName = "Requried")]
public string Remarks { get; set; }
I am having message in the resourcse but the code is not working. please let me know wheather i am even near to the solution.

I have a TableViewer in my Eclipse plugin.
When I was just using a regular label provider, my tooltips worked beautifully:
However, when I switched to have my LabelProvider implement IStyledLabelProvider, my tooltips went haywire:
Here is the code creating the StyledString
#Override
public StyledString getStyledText(final Object element) {
if( !(element instanceof MyInterface<?>) ) {
return null;
}
final String elemText = getColumnText(element, this.columnIndex);
final StyledString styledString = new StyledString(elemText == null ? "" : elemText);
if( !(element instanceof MyObject) ) {
return styledString;
}
final MyObject settingElement = (MyObject) element;
// grayed out text
if( settingElement.shouldBeGray() ) {
styledString.setStyle(0, elemText.length(), AdaptabilityStyles.GRAY_STYLER;
} else if( !settingElement.shouldBeBlue() ) {
styledString.setStyle(0, elemText.length(), AdaptabilityStyles.BLUE_STYLER);
}
return styledString;
}
And getTooltTipText()
#Override
public String getToolTipText(final Object element) {
return getColumnText(element, this.columnIndex);
}
What am I doing wrong?
As I was writing this question, I wanted to reference a bug report that I am familiar with that is related to tooltips. I looked at the bug report again and came across the following line:
For now, I simply try this :
ColumnViewerToolTipSupport.enableFor(commonViewer)
I wasn't calling that method when I created my viewer. When I tried that, my tooltips came back (though slightly different than they were before.
Currently I am looking for best practice in handling conditions inside the controller actions in asp.net mvc. For example -
public ActionResult Edit(int Id = 0)
{
var Item = _todoListItemsRepository.Find(Id);
**if (Item == null)
return View("NotFound");
if (!Item.IsAuthorized())
return View("NotValidOwner");**
return View("Edit", Item);
}
The above two conditions marked in bold is used in other actions inside the controller. So, in order not to repeat these conditions in all the actions. I have used the below approach.
[HttpGet]
[Authorize]
[ModelStatusActionFilter]
public ActionResult Edit(int Id = 0)
{
var Item = _todoListItemsRepository.Find(Id);
return View("Edit", Item);
}
public class ModelStatusActionFilterAttribute : ActionFilterAttribute
{
private readonly ITodoListItemsRepository _todoListItemsRepository;
public ModelStatusActionFilterAttribute()
: this(new TodoListItemsRepository())
{
}
public ModelStatusActionFilterAttribute(ITodoListItemsRepository todoListItemsRepository)
{
_todoListItemsRepository = todoListItemsRepository;
}
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
try
{
var Id = Convert.ToInt32(filterContext.RouteData.Values["Id"]);
var Item = _todoListItemsRepository.Find(Id);
if (Item == null)
{
filterContext.Result = new ViewResult() { ViewName = "NotFound" };
}
else if (!Item.IsAuthorized())
{
filterContext.Result = new ViewResult() { ViewName = "NotValidOwner" };
}
}
catch
{
}
}
}
I am unsure if this is the best practice in handling such scenarios. So, could someone please advise ?

usually you don't use action filter for so-called business logic of your web application - this is what the controllers are for. Action filter are rather for the whole stuff which is external to the actual logic - common case is logging, performance measurement, checking if user is authenticated / authorized (I don't think this is your case, although you call IsAuthorized method on the "Item").
Reducing code is generally good thing but in this case, I don't think putting the logic to action is a good way, because you;ve actually made it a bit unreadable, and unreadable code is in my opinon much worse than repeated code.
Also, specifically in your case, for all valid items you actually call the _todoListItemsRepository.Find() twice (for each valid item), which might be costly if this is some webservice call or db lookup.
If the code is just repeated throughout the actions, make a method out of it like:
private View ValidateItem(Item) {
if (Item == null)
return View("NotFound");
if (!Item.IsAuthorized())
return View("NotValidOwner");
return null; }
I have Documents like this in RavenDB 2.5:
public class SomeDocument {
public int Id { get;set; }
...other properties...
public bool ShowMember { get;set; }
}
with the ShowMember property being newly added.
Now I want to set ShowMember to true on all documents where it isn't set already.
I tried doing this with Eval Patching like this:
store.DatabaseCommands.UpdateByIndex("Raven/DocumentsByEntityName",
new IndexQuery { Query = "Tag:SomeDocuments" },
new ScriptedPatchRequest() {
Script = #"if(this.ShowMember == null){
this.ShowMember = true;
}" });
the operation completes without any errors, but documents that already have ShowMember set are still updated, despite the if
After playing around with it some more, doing
if(this.ShowMember == undefined)
seems to work.
Both
if(this.ShowMember == null)
and
if(!this.ShowMember)
don't work.
I hava an Action:
public ActionResult GetOrders(int id)
{
...
}
When I access it through hyperlink(~/Order/GetOrders/1), I want GetOrder return View(), the whole page.
When through #Html.Action("GetOrders"), I want it return PartialView() to be a part of a page.
Now i settled the problem using Erik Philips's method.
public ActionResult GetOrders(int id)
{
var orders = db.Order.Where(a => a.AdCompanyID == id).ToList();
ViewBag.AdCompanyName = db.AdCompany.Where(a => a.ID == id).Select(a => a.Name).First().ToString();
if (ControllerContext.IsChildAction)
{
ViewBag.isPartial = true;
return PartialView(orders);
}
ViewBag.isPartial = false;
return View(orders);
}
#{Html.RenderAction("GetOrders", new { id = Model.ID });}
#Html.ActionLink("Related orders", "GetOrders", new { id = item.ID })
in GetOrders.cshtml:
#if (ViewBag.isPartial == false)
{
...
}
to generate different view.
Queti M. Porta thanks all the same!
You can use the ControllerContext.IsChildAction.
public ActionResult Foo()
{
if (ControllerContext.IsChildAction)
{
return PartialView("GetOrdersPartial", model);
}
return View("GetOrders", model);
}
Also, I would recommend using Html.RenderAction.
Updated per Comment
I'd also mention that I've never had the need to do this, in my own experience. Either you really have a completely different view, or you are unaware that PartialView will return a view without a Layout.
An easy way would be to pass in a parameter into the action method to let it know how you want the view rendered.
public ActionResult GetOrders(int id, bool? isPartial)
{
return (isPartial.HasValue() && isPartial.Value)
? PartialView()
: View();
}
In the above example, we are passing in the isPartial, however, you can also check to see if the request was done via ajax using Request.IsAjaxRequest
Other than that, there aren't many other ways to determine the method of the request.
I've been Following this post To get my head around Lazy field of T, Which I think I understand, But I'm having trouble getting associated Field Data for a Part loaded this way
Aim - To show photo of blog post author on a blog post.
I want to add a content part "Content Author"
The part Editor should appear as a drop down list of orchard users.
(regardless of the content owner cms users should be able to pick the author)
I have added an image upload field to the User Content Type
I want to show the image of the user on the front end in the view for the Content Author Part
For the first part I have created the content type and used the lazy Filed of UserPart to get the username. However when I try and get the associated fields for the UserPart. There dosent seem to be any.
public class ContentAuthorRecord : ContentPartRecord
{
public virtual string AuthorEmail { get; set; }
}
public class ContentAuthorPart : ContentPart<ContentAuthorRecord>
{
internal readonly LazyField<UserPart> Owner = new LazyField<UserPart>();
public string AuthorEmail
{
get { return Record.AuthorEmail; }
set { Record.AuthorEmail = value; }
}
public UserPart Author
{
get { return Owner.Value; }
set { Owner.Value = value; }
}
public string AuthorName
{
get
{
if (Author == null)
return "Riders for health";
else
{
return Author.UserName;
}
}
}
}
public class ContentAuthorHandler :ContentHandler
{
private readonly IContentManager _contentManager;
public ContentAuthorHandler(IRepository<ContentAuthorRecord> repository, IContentManager contentManager)
{
_contentManager = contentManager;
OnActivated<ContentAuthorPart>(SetUpCustomPart);
Filters.Add(StorageFilter.For(repository));
}
private void SetUpCustomPart(ActivatedContentContext content, ContentAuthorPart part)
{
// Setup the getter of the lazy field
part.Owner.Loader(() => _contentManager.Query<UserPart, UserPartRecord>().List().FirstOrDefault(x => x.Email == part.AuthorEmail));
}
}
I would expect to be able to access the field with something like
(ImageUploadField.Fields.ImageUploadField)Author.Fields.FirstOrDefault(x
=> x.Name == "Photo");
form the within the part class
( although this makes every thing a bit brittle, hard coding a field name, but I'm not sure how eles to go about it)
Further Info
I have a HeaderPart with a Image field added via the cms (not in code) in the display handler I fetch the field like this
protected override DriverResult Display(HeaderPart part, string displayType, dynamic shapeHelper)
{
if (part.HeaderType == HeaderType.Full_width_hero_image)
{
var field = (ImageUploadField) part.Fields.FirstOrDefault(f => f.Name == "HeaderImage");
if (field != null)
{
return ContentShape("Parts_Header_ImageHero",
() => shapeHelper.Parts_Header_ImageHero(ImagePath: field.ImagePath, ImageTitle: field.FileName));
}
return null;
}
if (part.HeaderType == HeaderType.Full_width_hero_video)
{
return ContentShape("Parts_Header_VideoHero", () => shapeHelper.Parts_Header_VideoHero(VideoUrl: part.VideoUrl));
}
if (part.HeaderType == HeaderType.Body_width_video)
{
return ContentShape("Parts_Header_VideoBody", () => shapeHelper.Parts_Header_VideoBody(VideoUrl: part.VideoUrl));
}
return null;
}
This works, But I can do the same for a part loaded into a lazy field.
Cast to dynamic first, then the syntax becomes much simpler: ((dynamic)part.ContentItem).NameOfTheType.NameOfTheField.NameOfTheProperty
If you have added the fields to the User content type via the CMS interface, it may have added the fields to a different part to the one you expect. If you are adding fields to the User content type, by default it will have added the fields to a new part called 'User', not 'UserPart'. Try to following to search all parts in the content item:
(ImageUploadField.Fields.ImageUploadField)Author.ContentItem.Parts
.SelectMany(p => p.Fields).FirstOrDefault(f => f.Name == "Photo");
or directly from the 'User' part:
(ImageUploadField.Fields.ImageUploadField)Author.ContentItem.Parts
.First(p => p.PartDefinition.Name == p.ContentItem.ContentType).Fields
.FirstOrDefault(f => f.Name == "Photo");
