I've been researching optimization tips and tricks and have been playing around with disabling viewstate on my grids. However, I've ran into an issue where the ItemCommand event doesn't fire when disabling viewstate. This is an issue for me because nearly all my grids are functional; i.e. they are not display only grids. I also use DataKeyNames quite extensively and am curious if this is affected by disabling viewstate.
So, I just wanted to verify that it is expected that ItemCommand will not fire when viewstate is disabled or if I'm doing something wrong.

Finding more wierdness with this. Scenario:
Using a GridButtonColumn
Viewstate on grid is disabled
Have an ItemCommand event handler wired up to the grid
Scenario 1 - No confirm dialog on the GridButtonColumn
The item command event does not fire
Scenario 2 - Confirm dialog on the GridButtonColumn
Add a confirm dialog to the GridButtonColumn. I set mine to use RadWindow and configured text and title for the dialog.
The item command event fires in this case.
The problem is that I don't want/need a confirm dialog but, of course, I need the item command event to fire.
NOTE: DataKeyNames does seem to work with viewstate disabled so that is good!!!

Hello rh,
Disabling ViewState is not an option in complex controls like RadGrid - finally you will end with basic functionality! Better will be to get rid of ViewState (or compress) using RadCompression.
