I refer to the flickering of a GridDataBoundGrid,
when I save the content of the grid to a dataset.
(see also http://www.syncfusion.com/Support/forums/message.aspx?MessageID=21924)
I overcame this problem really simple:
First I set the visible property to false,
.code for updating etc etc
then I set the property to true.
It also speeds up the process big time.
