Hi.

I found RadVirtualGrid fires CellValueNeeded everytime, when user resize some column. So resizing isn't smooth, especially when grid is expanded to fullscreen.

Why so? Column resizing doesn't changing cell values, just their appearance, and there is no needing to aplly new value. Is there a way to awoid firing CellValueNeeded on every column resize event?

Hello, Vitaliy,   

Due to the virtualization mechanism that RadVirtualGrid currently uses, when you resize the columns, some of the columns may become invisible and other may get visible. That is why the CellValueNeeded event is triggered to ensure that the proper values will be displayed within the cells. However, I have logged it in our feedback portal in order to investigate if it is possible to improve the virtualization mechanism in this case.. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

I have also updated your Telerik points.

I hope this information helps. If you have any additional questions, please let me know. 

Regards,
Dess
