Is it possible to send an ajax request to a user control file with the extension .ascx?

Question

Is it possible to send an ajax request to a user control file with the extension .ascx?

I am trying to interact with a user control on my page through ajax.

Is it possible to make an ajax request directly to the user control (.ascx) instead of .aspx or .ashx files?

Answer №1

When working with an ASP.NET MVC application, you can easily load a partial view like so:

public ActionResult Foo()
{
    return PartialView();
}

Simply send an AJAX request using the following code:

$('#someDiv').load('/home/foo');

This will load the Foo.ascx partial view inside a div seamlessly.

For classic ASP.NET WebForms applications, you'll need to set up a generic handler to render the user control's content in the response. Here's an example of how this could be done:

public class Handler1 : IHttpHandler
{
    public void ProcessRequest(HttpContext context)
    {
        using (var writer = new StringWriter())
        {
            Page pageHolder = new Page();
            var control = (UserControl)pageHolder.LoadControl("~/foo.ascx");
            pageHolder.Controls.Add(control);
            context.Server.Execute(pageHolder, writer, false);
            context.Response.ContentType = "text/html";
            context.Response.Write(writer.GetStringBuilder().ToString());
        }
    }

    public bool IsReusable
    {
        get { return false; }
    }
}
