Hello,
I have an unbound grid with 30 columns and not more than few hundred rows. When the application is in full screen mode (grid takes almost whole screen), the grid is reacting quite slow. When using keyboard to navigate it takes up to 2 seconds to move to next cell even on a relatively fast PC (Intel Core 2 Duo, 1,86 Ghz, 2 GB RAM). It happens only when navigating left/right, up/down works fine. I noticed that when going into edit mode then all visible rows are refreshed, then when leaving edit mode visible rows are refreshed, and finally when the focus moves to another column all visible cells are refreshed. There is quite a lot of cells to refresh and that seems to be causing the slowdowns. Is there any way to make the grid respond faster to keyboard actions (refresh only the affected cells/columns/rows) ?
I'm using Telerik Controls for WinForms (.net 2.0), tried it on 2008 Q3 SP2 and the newest demo 2009.2 729 (Jul 29, 2009)
Thanks in advance
