How to use ajax with asp.net webforms

Question

Is there any way to use ajax I'm using Jquery for this) with asp.net webforms without having to run through the pages life cycle?

Depending on what you're trying to do, you could use Web Methods or Http Handlers. Web Methods might be a bit easier, and are just server side static functions which are decorated with the [WebMethod] attribute.

Here's an example:

C#:

[WebMethod]
public static string SayHello(string name)
{
    return "Hello " + name;
}

ASPX:

<asp:ScriptManager ID="sm" EnablePageMethods="true" runat="server"/>

<script type="text/javascript">
    #(function()
    {
        $(".hellobutton").click(function()
        {
            PageMethods.SayHello("Name", function(result)
            {
                alert(result);
            });
        });
    }
</script>

<input type="button" class="hellobutton" value="Say Hello" />
