I have just implemented the RadGridView, which was an upgrade from the standard .net DataGrid.  I have about 100 items in the grid, with about 12 columns and something as simple as a scroll moves very slow.  Scrolling is very jerky, and not smooth.  I also noticed that if I add sorting and grouping, there are random delays as new items are added to the grid.  These delays can be as long as a few seconds even though I have no more than 100 items in my grid.   I have profiled the app, and it says the hottest function call is
Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.MeasureOverride
This can be make or break for us as we need a low latency high performance data grid.

Hello,

I have tested scrolling in grouped scenario on our WPF Demos and I did not encounter such delays. May I ask you whether you use our latest version - Q2 2012 SP2? Do you experience slowness with the vertical or the horizontal scroll? Do you have any additional logic added? How have you defined your GridView?

Kind regards,

No, I'm using Q1, I will upgrade to Q2, and get back to you.  Scrolling is slow using vertical and horizontal scrolling.
