I have a RadGridView using cell Template have another radgrid causing vertical scroll lose postion when move horizontal scroll bar.
<telerik:RadGridView Height="500" ItemsSource="{Binding XyzData}" AutoGenerateColumns="False" CanUserDeleteRows="False"
CanUserInsertRows="False" EditTriggers="None" CanUserSelect="False" RowIndicatorVisibility="Collapsed"
GroupRenderMode="Flat" RowHeight="18">
<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn Header="A_ID" DataMemberBinding="{Binding A_Id}"/>
<telerik:GridViewDataColumn Header="DGroup" DataMemberBinding="{Binding D_Group}"/>
<telerik:GridViewDataColumn Header="UID" DataMemberBinding="{Binding U_Id}"/>
<telerik:GridViewColumn Header="Recommendation" CellTemplate="{StaticResource RecommendationItemTemplate}" />
</telerik:RadGridView.Columns>
</telerik:RadGridView>
last column Template have another RadGridView, when scroll horziontal scroll bar to right and last columns comes to view sate vertical scroll bar jumping and row height changing based on radgrid size in cell. is their a solution not to jump vertical scroll bar keep same postion when scroll horiziontal scroll bar. thanks

Hello Sri,
Thank you for the provided code snippet.
Although I cannot be absolutely certain without being able to replicate this at my end, I assume the reason for this behavior is the control's UI virtualization mechanism. In other words, when you scroll the cells containing the child RadGridView out of the viewport, they are recycled, and thus - the height of the row is reduced and vice versa.
If this is indeed the case, I have two suggestions:
- You can set a fixed row height to ensure that the rows do not resize. This can be accomplished via the control's RowHeight property.
- If this does not have a negative impact on the performance, you can set the EnableColumnVirtualization property to False.
Please let me know if any of these approaches works for you.

- You can set a fixed row height to ensure that the rows do not resize. This can be accomplished via the control's RowHeight property.
- - Can't set row height fixed because of child radgrid doesn't know the number of rows.
- If this does not have a negative impact on the performance, you can set the EnableColumnVirtualization property to False.
- - not working with row virtualization and column virtualization. Thanks
I want to clarify that my suggestion is to set the two properties on the parent RadGridView instance. This way even if the height of the child grid exceeds the row height a ScrollViewer should be displayed and the number of rows should not be of importance.
As for the column virtualization, please specify whether you've set this to False on the parent RadGridView. If that is the case, I'm uncertain as to why it does not have any effect.
If possible, please send over a small sample project which demonstrates your setup and the issue you observe and I will gladly assist you further.
