RadDatagrid IndexOutOfRange issue

[petitponey]

Hi,

I have an IndexOutOfRange error but this occurs rarely and I can't reproduce it. Please could you investigate if a check can be added to avoid IndexOutOfRange
exception?

 Acording the stack trace, MeasureVertically seems to call UpdateAverageLength with a bad endIndex.

I use the last published version of Telerik UI for Windows 8.1 (2016.1.113.45)

Index was outside the bounds of the array.
Stack Trace:
System.IndexOutOfRangeException
   at Telerik.UI.Xaml.Controls.Grid.IndexStorage.ValueForIndex(Int32 index, Boolean approximate)
   at Telerik.Data.Core.Layouts.CompactLayout.UpdateAverageLength(Int32 startIndex, Int32 endIndex)
   at Telerik.UI.Xaml.Controls.Grid.NodePool`2.MeasureVertically(RadSize availableSize, Double offset)
   at Telerik.UI.Xaml.Controls.Grid.NodePool`2.OnMeasure(RadSize availableSize, Double offset, Int32 frozenElementsCount)
   at Telerik.UI.Xaml.Controls.Grid.Model.GridModel.MeasureCells(RadSize newAvailableSize)
   at Telerik.UI.Xaml.Controls.Grid.RadDataGrid.OnCellsPanelMeasure(RadSize newAvailableSize)
   at Telerik.UI.Xaml.Controls.Grid.Primitives.DataGridCellsPanel.MeasureOverride(Size availableSize)
