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"

Hello,

I have prepared a sample project for you that uses amount of data close to a real time scenario - 100000 items with 50 properties (columns). Is the performance on your side similar or worse? I believe that your real project utilizes much more complex UI layout, and this may cause certain difference. You can also send us a runnable sample project that we can debug on our side and give you guidance for improving performance.
