Is it possible to place a WebMethod in an ascx.cs file (for a UserControl) and then call it from client-side jQuery code?
For some reasons I can't place the WebMethod code in an .asmx or .aspx file.
Example: In ArticleList.ascx.cs I have the following code:
[WebMethod] public static string HelloWorld() { return "helloWorld"; } In ArticleList.ascx file there I have the call to the WebMethod as follows:
$.ajax({ type: "POST", contentType: "application/json; charset=utf-8", data: "{}", dataFilter: function(data)//makes it work with 2.0 or 3.5 .net { var msg; if (typeof (JSON) !== 'undefined' && typeof (JSON.parse) === 'function') msg = JSON.parse(data); else msg = eval('(' + data + ')'); if (msg.hasOwnProperty('d')) return msg.d; else return msg; }, url: "ArticleList.ascx/HelloWorld", success: function(msg) { alert(msg); } }); and the error from firebug is:
<html> <head> <title>This type of page is not served.</title> How can I sucessfully call the server-side WebMethod from my client-side jQuery code?

The WebMethod attribute is added to each method we want to expose as a Web Service. ASP.NET makes it possible to map traditional methods to Web Service operations through the System. Web. Services.
User controls. User controls are containers into which you can put markup and Web server controls. You can then treat the user control as a unit and define properties and methods for it. Custom controls. A custom control is a class that you write that derives from Control or WebControl.
WebMethod should be static. So, You can put it in the user control and add a method in the page to call it.
Edit:
You can not call a web method through a user control because it'll be automatically rendered inside the page.
The web method which you have in the user control:
public static string HelloWorld() { return "helloWOrld"; } In the Page class add the web method:
[WebMethod] public static string HelloWorld() { return ArticleList.HelloWorld(); // call the method which // exists in the user control } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
