This is probably not about the WHDG really but im hoping for some inspiration.

I have a reasonable complex page, its a web content form but there isnt much on the master page, mainly for the menu and a few other little things like a message area.

On the content form I have one update panel for header information which contains a few text fields and some date pickers etc. Underneath this are two WHDG's located each in its own td in a table row for positioning.

In the header update panel I have some buttons like save and edit etc for the header info. The problem I am having is that it seems to take anything from 2-8 seconds to start postback when I first load the page if I dont expand the grids it happens in about 2 seconds, once the grids are all expaned this increases to 8 or more seconds before the screen grays out etc. Once the postback starts its all over in about a second and a half.

I knows its difficult without the code, but there is simply too much linked stuff to post a working copy. I was hoping someone might have  some inspiration. I have tried to  isolate the issue but bar removing almost everything nothing seems to make a difference.

Cheers
