如何从内容页面usercontrol更改主页面控件值 [英] How to change the master Page control value from content page usercontrol

问题描述

您好我用母版页创建网页。在我的内容页面中，我有一个gridview的用户控件。所以我创建了Gridview Editing事件。在该事件的c＃页面中，我必须将值设置为主页面控件。所以我正在访问该控件，如下所示。但它没有用。如果我在usercontrol事件之外使用此方法意味着它正常工作。但是在那个不起作用的usercontrol事件之间。

Hi i m create webpage with master page. In my content page i have a usercontrol for gridview. So i m creating Gridview Editing event. In c# page in that event i have to set the value to master page control. So i m accessing that control like following. But it is not working. If I used this method outside of the usercontrol events means it is working fine. But in between that usercontrol event that is not working.

((Label)Page.Master.FindControl("lblMsg")).Text = "Updated Successfully";

如何解决这个问题？

如果我使用断点检查值是否改变了值。但它没有在网页上显示

How to solve this problem?
If i check the value using breakpoint that value is changed. But it is not showing on the webpage

<pre>Label l=((Label)Page.Master.FindControl("lblMsg"));
l.Text = "Updated Successfully";</pre>

然后我检查''l''文本属性是否已更改。它已成功更新。但它没有在我的网页上显示

Then i check that ''l'' text property it is changed. It has ''Updated Successfully. But it is not showing on my webpage
