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