Executing ASP.NET Code Behind Function Using JavaScript

I've created a web method to delete a user, which I'm trying to call from JavaScript. However, it doesn't seem to be working as expected. I am passing the selected index value from a listbox within a user control to my web method. Despite looking for solutions on multiple websites, I haven't been able to find one that works. There are no error messages being displayed, and everything else appears to be functioning properly. I even attempted to call the function from a public sub in the code behind, but still had no luck. Any suggestions or advice would be greatly appreciated!

Answer №1

You might want to consider utilizing the JSon method to invoke the web method. Below is a straightforward example:

 $.ajax({
 type: "POST",
 contentType: "application/json; charset=utf-8",
 url: "yourpage.aspx/yourmethod",
 data: "{}",
 dataType: "json",
 success: function(data) {
 //Implement code to display the data
 },
 error: function(result) {
 alert("Error");
 }
 });
