Entire Page refreshes even though gridview is in an update panel

Question

I have a gridview that is within an updatepanel for a modal popup I have on a page.
The issue is that the entire page refreshes every time I click an imagebutton that is within my gridview. This causes my entire page to load and since I have grayed out the rest of the page so that the user cannot click on it this is very annoying.

Does any one know what I am missing.

Edit: I entered a better solution at the bottom

Answer 1

Make sure you have the following set on the UpdatePanel: ChildrenAsTriggers=false and UpdateMode=Conditional

Answer 2

do you have ChildrenAsTriggers="false" on the UpdatePanel?

Are there any javascript errors on the page?
