How to load gridview in page without postback
Hello,
I have a page with many panels that have divs and quite a few calls to the database. This is what I need to do but don't know how to go about it. On the click of a button I am using javascript to do some validation and then I need to populate a gridview in a hidden div with a call to the database and passing a querystring that is the sql. All this without full postback as I don't want all the elements above the grid to clear. I thought about xmlhttprequest and ajax and the updatepanel but I haven't seen a good enough example that could be modified to suit what I need. My site has master and content with one usercontrol. Can someone show me a working example or just send me some links of good examples that load a grid in the same page as I already have. Thanks.

codecruiser: I am really new to ajax. I have looked at many samples but don't understand enough yet to modify any of them so I decided to use the updatepanel. It works and the grid and div load and the rest of the page does not post back but a second after it loads the updatepanel disappears. I have a trigger set with asynpostback and id as the button and I have the script manager in a usercontrol that sits in this page and I have partialpagerendering set to true. I also have if not page.ispostback on the page load in codebehind but I am still doing something wrong. Can you tell me how to troubleshoot this?
