Error when accessing Count property of an IList in ASP.Net MVC 3

When I开发者_如何学编程 try to display the count property of an IList in my ViewModel on the View i get the following error:

The property System.Collections.Generic.IList`1[[WebUI.ViewModels.ItemViewModel, WebUI, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]].Count could not be found.

The line in my view that riases the error is:

<td>@Html.DisplayFor(modelItem => item.ItemCollection.Count)</td>

Upon inspection, the collection is populated correctly and this line of code works correctly:

<td>@Html.DisplayFor(modelItem => item.ItemCollection[0].Id)</td>

I clearly have a reference to System.Collections.Generic so I suspect the error is refering to the WebUI.ViewModels.ItemViewModel object. This is accessible when debugging and the error is only raised when accessing Count.

Why dont you try:

<td>@Model.ItemCollection.Count</td>

Without the HtmlHelper...

You can Cast IList to List then use List.Count

Try this:

<td>@Html.DisplayFor(modelItem => ((List<WebUI.ViewModels.ItemViewModel>)item.ItemCollection).Count)</td>
