calling an ascx page method using jquery

Question

I know that I can call a page method with jquery using the following syntax

$.ajax({
  type: \"POST\",
  url: \"Default.aspx/GetDate\",
  data: \"{}\",
  con         


        

Answer 1

This is an example of rendering a user control through a jQuery web service call.

Answer 2

Here is a way to get around the limitation of only having Page methods (ScriptMethod) available in ASPX pages. This example builds a proxy using a page base class and a special attribute to decorate methods in your ASCX page's code-behind and have those accessible via the client.

Creating a Page method (ScriptMethod) within an ASCX user control using AJAX, JSON, base classes and reflection

Answer 3

I don't think it will be possible, as user controls aren't meant to be accessible externally (outside of a page). I suggest just using a script service (a web service).

Answer 4

What about creating the method on the .aspx page that does what it needs to with the information from the control? I know people go back and fourth on what controls are supposed to contain or not contain, but if the control only contains properties and objects, I would think having the function in the .aspx page could work for you. Obviously there would be many trade-offs.

Answer 5

I don't think it's possible by requesting the ascx file directly--i.e. supplying "MyControl.ascx" as the url parameter to $.ajax(..). The ascx file isn't exposed directly by the web server.

You can, I believe, supply the url of the aspx page containing the user control--i.e. if an instance of MyControl.ascx lives on MyPage.aspx you would have to supply "MyPage.aspx" as the url parameter. It sounds like that might defeat the purpose for what you're trying to accomplish though.

EDIT: What Clyde said below seems like a good idea. I'm doing something similar myself by including the ascx control on a page whose job is more or less just to host it for access from client-side script.

Answer 6

I would create a Generic Handler (.ashx) which Loads the control and writes its rendered HTML to the Response.
