Sometimes GridViewVirtualizingPanel Items are messed up

[Valdo]

In certain conditions, my GridView becomes like this (see attachment). It happens when retrieving data from server and an error occurs. It's hard to reproduce or make a sample project, so any ideas on why this is happening would be appreciated.

Hello,

 Can you post more info about the grid settings, binding and version? Do you have also any custom styles? 

Best wishes,

Thanks for replying.

I'm using styles only to change color scheme. And the settings are simple:

<DataGrid:RadGridView ItemsSource="{Binding Items}"

AutoGenerateColumns="False" RowIndicatorVisibility="Collapsed"

ShowGroupPanel="False" ShowGroupFooters="False"

BorderBrush="#FFE2E2E2" BorderThickness="1,0,1,1"

DragDrop:RadDragAndDropManager.AllowDrag="True"

DragDrop:RadDragAndDropManager.AllowDrop="True"

CanUserDeleteRows="false" EditTriggers="None"> 

  

  <DataGrid:RadGridView.Columns> 

    <Telerik:GridViewDataColumn 

         DataMemberBinding="{Binding Data1}" Header="Header 1"/>

    <Telerik:GridViewDataColumn 

         DataMemberBinding="{Binding Data2}" Header="Header 2"/>

    <Telerik:GridViewDataColumn 

         DataMemberBinding="{Binding Data3}" Header="Header 3"/>

  </DataGrid:RadGridView.Columns>

</DataGrid:RadGridView>

UPD: It seems to me that the problem is in the PrepareContainerForItemOverride method. Sometimes it sets VerticalContentAlignment to Center instead of Stretch. And this only occurs, when adding items to GridView which is not visible on screen (on other tab for example). Any ideas why?
