Setting the response for an Ajax request

[Mike]

I have a very basic question about RadAjaxManager that I was unable to answer yet. How to pass data back to the client-side response handler:

Client-side, I might do something like this:

RadAjaxManager1.ajaxRequest(arg);

Server-side, I then do something like this:

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

  string arg = e.Argument;

  // do something

}

Client-side, I then handle the response as so

function OnReponseEnd(sender, eventArgs)

{
}

My basic question is - how to pass data back to OnResponseEnd? What can I do server-side that will generate data that I can then process in OnResponseEnd? I'm more accustomed to doing ajax more bare-bones, like through jQuery, where I can pass params back and forth. I know I can add ResponseScripts server-side in order to pass data, but that's a bit clunky.

Thanks

Hello Mike,

ResponseScripts is one option. Another is to update HTML content you can then check in OnResponseEnd. For example, you can update a hidden input on the server and get its value on the client after the response arrives. Yet another approach is to use ScriptManager.RegisterDataItem() to send a data item to a control on the client.
