[Solved] Autopostback for a combo inside edittemplate causes the datepicker to refresh

[newbie]

I have a few combo boxes inside the grid with AutoPostback="true" as I need to do some handling on the selectedIndexChanged event.

I have around 5 datepickers with a shared calendar on the page.
The autopostback causes the datepickers to flicker. There is a page flash and the datepickers seem to load again.
How can i avoid that?
