This is some really strange behavior. Are you using the ContentTemplate of the RadWindow to host your popup with the RadComboBox? If so can you please inspect the z-index values the combo box dropdown has as well as any custom positioning your RadButtons may have? Is is possible that they are above the dropdown so actually the click propagates to them? Also, is the grid event triggered when you try to open the combo's dropdown or when you select an item that is above the grid's column? Do you have any server-side handlers attached to the combobox?
I tried reproducing this scenario by basing it on the Automatic operations grid demo
and on the Use as controls container window demo
, but things seem to work properly with me and the events are not triggered by the combo: http://screencast.com/t/CNu2iHrSRrx
. I am also attaching the modified page as I ran it. Please examine it and try to locate any major differences in the setup with your original page that will help you correct the behavior. If you are not able to do so yourself please post the changes needed to reproduce the issue so we can examine it locally and pinpoint its cause.
