GridView Exception

[Victor Manuel Gonzalez Tellez]

Hi! Good day. We are facing some issues when having more items, so an scroll down its needed. The problem is when we load the list.  I have an ObservableCollection which is bounded to the GridView, and everytime you load the data from a WCF service, the list is cleared and filled again, is when the exception occurs. The code its very simple, ItemSource to the ObservableCollection, and SelectedItem to CurrentItem for edition, after edition finishes, the list is loaded again. This only happens when having ceratin number of elements. Thanks!

The exception message is this:

Message: Unhandled Error in Silverlight Application

Code: 4004   

Category: ManagedRuntimeError      

Message: System.IndexOutOfRangeException: Index was outside the bounds of the array.

   at Telerik.Windows.Controls.GridView.IndexTree.CumulativeValue(Int32 endIndex)

   at Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.ArrangeOverride(Size finalSize)

   at System.Windows.FrameworkElement.ArrangeOverride(IntPtr nativeTarget, Single inWidth, Single inHeight, Single& outWidth, Single& outHeight)

Yes, we're using Q3 build 1314, and we're facing this issue, when we have a list that requires a vertical scroll, and we select and item at the bottom to delete it. After it's deleted, the load of the ObservableCollection is done again, and it's where we have the exception thrown.

Hi,

We believe that we've fixed this problem already - please try our latest internal build and let me know how it goes.

Hi,

I have the latest version of Telerik SL controls installed (April 2010) and it happens to me.

I have a grid for managing lookup. So the form is very simple. I keep inserting rows. Works fine until I cannot insert any more rows. Even after I restart the application I get the same error. When I delete the record I can add the record. Magical number of records in my case is 8. 

Thanks

Miroslav

Hi Miroslav,

Can you send us an example project via support ticket where we can reproduce this?
