ASP.NET: ajaxToolkit's HoverMenuExtender slows down sorting in GridView

Question

I have a GridView inside UpdatePanel and also a HoverMenuExtender declared. GridView also has Paging and Sorting enabled and PageSize is 25.

Right now I'm working on a mockup of the actual application so I'm using a mock DataSet with only 20 records.

Problem is when I try to sort gridView by clicking on a column it's VERY SLOW. It takes about 2-3 seconds to "sort" and "display" this 20 rows of mock data. But, what we discovered is that if I take out the HoverMenuExtender, everything works as it should. In that case sorting is instant, so problem is more in "display" and none in "sort".

Is there a way to speed up HoverMenuExtender's rendering or should I just forget about using it?

Hi Goran,

I've come across a similar issue using gridviews and ajax animations with internet explorer. My ultimate solution was to remove the animations as it was just ridiculously slow for no reason on IE (worked fine in firefox).

What browser are you using?

I guess there is no really a solution for this issue.

I decided not to use this extender with my gridview.
