Full postback triggered by LinkButton inside GridView inside UpdatePanel

Question

I have a GridView inside of a UpdatePanel. In a template field is a button I use for marking items. Functionally, this works fine, but the button always triggers a full page

Answer 1

I had an issue where I had one form working fine (page1), another doing whole post backs (page2). Turned out when I made the 2nd page, I had done a bit too much cut/paste, and it still had a javascript call in the form definition.

< form id="form1" runat="server" onsubmit="return checkstuff();">

But checkstuff was not defined in page 2.

deleted the onsubmit, and the partial posts started working.

In the working page - page 1, checkstuff was defined, but was just a stub, which did nothing more than return true. Just for grins, I put an alert in checkstuff, and sure enough, it is called for all submits, partial or not. And, if I changed the stub to just return false, nothing happened at all.

Point in all this, the javascript is still exercised, as if a full page is being submitted. So double check your client side scripts.
