Question

I’m using a repeater on my page. I want to populate this repeater based on a selection from a dropdown but with no page refresh.

Here is the sequence of events:

1. user selects an item in a dopdown
2. Show the results (bind a server-side control and then render it back to the page)

Now to show the results I need to call a server-side method where I pass a couple Ids from the client to the server and then the server rebinds the control using some logic in the code-behind of this page.

Not sure if this is possible. I tried to do a redirect and send the values through a querystring but obviously that performs a refresh of the page.

I’m simply trying to call a code-behind (server-side) method after the user selects a dropdown item and then just paint the results from the now bound repeater on the page using jQuery’s .html().

I think this isn’t possible with a repeater because it’s server-side right? If not I’ll just have to make a jquery ajax call to my handler like I’ve done and just paint the response html that I created back to a div on the page to create the list instead of a repeater.

I ask because I’m trying to also use the jqGrid…figured there was a way I can update the grid after a user selects something in another dropdown on my page and perform some kind of ajax call to somehow bind that grid but the jqGrid is a server-side control…so I do not think it’s possible?

Maybe you can use ASP.net control named “UpdatePanel” (MSDN) in place of client side jquery code.

Only The controls in the panel will be refreshed. Take care with repeater I think the attribute “ChildrenAsTriggers” of update panel doesn’t work you have to declare the dropdown list as a trigger.

Or Maybe you can consume a asmx webService with Jquery to bind manually the repeater.. But I never made that.. (For example)
