We are using celltemplate and editcelltemplate dynamically vs in XAML. We are also have grouping enable on a column.

As user has to click row , click cell to enter data or additional click for combo box ( too many clicks). So we have tried to enable CellClick EditTriggers. With cellclick enable it is very slow to go into the cell to enter data.

I have tried to use demo sample that has celltemplate example i.e
http://demos.telerik.com/silverlight/#GridView/CellEditTemplate

Enabled cellclick and I see the same slowness when column is grouped vs cellclick with out grouping. Are we missing any here? Is there any way to improve the user clicking on cell to going into edit mode?

Thanks

Hi Praveen,

The problem comes from the fact that when RadGridView is grouped and edit operation is committed (clicking on cell of another row) all row get recreated. We are currently working on a way to optimize this scenario. I have created a PITS (#1652) item that you can use to track the progress of this issue.

Thanks for your feedback and sorry for the inconvenience this might cause.

Kind regards,

Hi Praveen,

We have refactored our grouping implementation to not refresh the whole view when an edit is committed for Q2 2010. Can you please download our Q2 2010 Beta version and verify how this new behavior is working for you?
