The Asp.Net’s ajax implementation using UpdatePanel is really slow and experienced people know that the whole ViewState is sent to server even though we are only interested in doing partial postback. So I started using Jquery but I don’t know how do I make a request from Jauery to server and get UserControl’s HTML in output? The UserControl in turn may have some controls like textbox etc.

In short, I want some functionality that Asp.Net MVC has which uses RenderPartial.

    In the context of Page, you can load a control and render its output.

    Control myControl = Page.LoadControl("myControl.ascx");
myControl.RenderControl(System.Web.UI.HtmlTextWriter);

    But that just gets the html that the control would output to the page. This is fine if your control has no more events and just does something onload, but if you want to postback from it, then this will not work (as mentioned in the comments.)
