Very slow postback

[Girish481]

Hello, I have placed a table of 2 columns 5 rows and 4 dropdown lists and 2 textboxes in its columns. Out of these 4 dropdown lists, i have enabled autopostback property; but when i run the page and changes/select the options of this dropdown list; this control's postback do'nt fire immediately; it takes so many minutes and/or seems like hang the page. It is not on a specific item; sometime it works fast and sometime i select the items it again seems like hand / not postbacked. Why this is like so; and how to resolve it. Thanks & Regards Girish Sharma

It may cause of very heavy viewstate text in your page. Check your page view source if yes then google for "save viewstate in database"

What would happen if you changed the row to a single cell with a user control that has the dropdowns. You cound wrap the user control in an update panel?
