fast row selection on form


I have a GRID on a webform and have some slow code on OnServerRowSelected event, 
The form works fine as long as I wait between click on rows, if I click on rows without waiting, the code loses sync, that is i get only some of the OnServerRowSelected events.
I assume that it is because the events are lost when the panel is re-rendered.

I am using 


but it is not enough, looks like the Waiting Popup is not fast enough and sometimes it just hangs 

Is there a way to prevent the user from selecting a row before the handling of the last OnServerRowSelected is completed ?
