I have a pretty simple scenario where I have 2 RadComboBox controls in a RadGrid EditMode="Popup". Changing the value of one comboBox enables/disables the other, so I handle the server-side OnSelectedIndexChanged event handler (w/ AutoPostBack="true") of the primary combo. This works just fine, but the small problem is that the popup temporarily disappears, similar to a screen flash on a regular postback. Exact same code with EditMode="EditForms" worked with no screen flash. Any way around this?

Hi Steve,
I suggest you to perform the same on the client in order to avoid the postback (enable()/disable() methods). Please check this article for more info:

Client-side won't work in this scenario because the dependent comboBox is enabled/disabled based on a database check (which means I need to goto the server). I'd really like to use this "popup" edit form functionality built into RadGrid (as opposed to using RadWindow), but this little screen flash thing might make it unusable. Any help is appreciated.

Hello Steve,
Unfortunately in case of traditional post-back (or ajax request) the grid will be disposed (and recreated) which cause this screen flash. You can invoke on the client for example a static page or web service method to check desired field value in your data-base to avoid traditional post-back or ajax request.
