如何访问静态 Web 方法中的页面控件? [英] How to access page controls inside a static web method?

问题描述

我使用静态 WebMethod 方法使用 jQuery 调用了代码隐藏方法.

I have called a Code behind method using jQuery using a static WebMethod method.

该 Web 方法调用成功，但是当尝试访问文本框控件时出现错误.非静态字段、方法或属性需要对象引用.

That web method call was success but when tried to access a text box control it is giving error. An object reference is required for the non-static field, method, or property.

[WebMethod]    
public static Savedata()
 {
     //code to insert data to DB

     //after inserting data successfully i need to change the text box text like following.        
      txtStatus.Text="Data Received";   
 }

推荐答案

正如@Tim Schmelter 所提到的，这不能回答这个问题，因为您无法从网络方法访问页面控件.

As mentioned by @Tim Schmelter This doesn't answer this question because you can't access page's controls from a webmethod.

请通过asp.net 从静态函数访问控件

[WebMethod] 的全部意义在于它们不运行 ASP.Net 页面生命周期.这样，它们既快速又可并行.您的控件不存在.

The whole point of [WebMethod]s is that they don't run the ASP.Net page lifecycle. This way, they're fast and parallelizable. Your controls don't exist.

您的问题与如何在静态网络方法中获取控件重复
