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?

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