Poor performance of Horizontal Scrollbar on RadGridView
We are using Radgridview in our wpf application which is autogenerated using Class Models. When the number of columns are quite huge(more than 35-40 columns), the performance of the horizontal scrollbar is quite poor and even worst when the data on the Grid is huge. Infact the experience it gives while scrolling seems as if the scrollbar is continuously growing. I have tried the following settings on the RadGridView in the xaml but there is no significant improvement in the performance:

EnableColumnVirtualization="True" EnableRowVirtualization="True" VirtualizingPanel.IsVirtualizing="True" VirtualizingPanel.VirtualizationMode="Recycling" ScrollViewer.CanContentScroll="False" ScrollMode="Deferred"

Hi,

I would suggest you to check RadGridView Tips and Tricks article for optimal performance:
http://www.telerik.com/help/wpf/radgridview-performance-tips-tricks.html
You can also give a try to RadGridView Lightweight templates which main idea is to limit the number of visual elements within the templates in order to speed up the performance. More information can be found here:
http://www.telerik.com/help/silverlight/gridview-overview-lightweight-template.html

In case none of the suggested approaches helps, please open a support ticket and send a runnable project demonstrating the problem.

Regards,
Vera
