[Solved] Scrollbar size incorrect when using IsVisible on columns

[Patrick]

Hello,

I'm using the RadGridView and have many columns initially set as IsVisible=False, they're are only 5 columns and a scrollbar is not present. When I later set IsVisible=True to a few columns the scroll bar appears(on the bottom) as would be expected but its not the correct size. When I move the scrollbar over to the right to see my newly visible columns the size of the scrollbar shrinks as I move over and I don't have a correct indication from the scrollbar of how much more I have to scroll. Eventually if I scroll all the way to the right the scrollbar size is correct the movement of it works as expected. Any ideas on how to get it to size correctly after making columns Visible?
I've noticed this with two different GridViews that we are using in our product. Thank you, Patrick

My GridView in my XAML is set as such:
<telerikGridView:RadGridView x:Name="xRadDataGrid" Visibility="Collapsed" FontSize="14" ItemsSource="{Binding PagedSource,ElementName=xRadDataPager}" Height="455" HorizontalAlignment="Stretch" AutoGenerateColumns="False" Grid.Row="2" ShowGroupPanel="True" VerticalAlignment="Top" ElementExporting="mygrid_ElementExporting" IsReadOnly="True" GotFocus="xRadData_GotFocus" MouseRightButtonUp="xRadDataGrid_MouseRightButtonUp" Sorting="gridPlayerStats_Sorting"/>

Hi Patrick,

 This happens because of column virtualization - when you set IsVisible to the columns and before you scroll to reveal them, they don't yet 'exist' visually, so there's no way to determine their size. You can, however, set the EnableColumnVirtualization property of RadGridView to false, or you can even try manually setting the Width property of your columns (although I'm not sure if the latter approach will work correctly).

Yavor,

EnableColumnVirtualization="False" worked perfectly. Thank you!
