问题 I have a [WebMethod] and i want to assign values to a text box using the this code: [WebMethod] public static void MyMethod(string s) { //TextBox1.Text = s; //Here how can i access the textbx? } 回答1: You can't.

Instead, you should use Javascript (better) or an UpdatePanel (worse). 回答2: in case of static method(ie, page method asynchronous

(web controls) I've been trying it for about half an hour and since I can't get it to work I'm wondering if it's even possible. Note: Just to be clear, when I try to call the ascx page I am updating the url in

问题 I am having issue with my pagemethod + url rewrite. When using regular URL: http://myweb.com/mypages/abc.aspx call to the PageMethod works fine.

Call ASP.NET PageMethod/WebMethod with jQuery - returns whole page

由 不打扰是莪最后的温柔 提交于 2019-11-26 18:37:32
jQuery 1.3.2, ASP.NET 2.0. Making an AJAX call to a PageMethod (WebMethod) returns the full/whole page instead of just the response. A breakpoint on the page method shows it's never getting hit.

I even tried adding [ScriptService] at the top of my class to see if it helped, but it did not. I have seen this post Jquery AJAX with ASP.NET WebMethod Returning Entire Page which had my same symptoms, but I am still having a problem. I read http://encosia.com/2008/05/29/using-jquery-to
