推荐答案

你最喜欢这样做得到内容页面更新面板外的主页面的标签控件



标签lblInfo =（标签）这个。 Page.Master.FindControl（labelID）;



然后在更新面板中使用该lblInfo



ie lblinfo =XXXX;



我希望它能够工作

Better you do like this get the label control of the master page outside the content page update panel using

Label lblInfo = (Label)this.Page.Master.FindControl("labelID");

and then use that lblInfo inside the update panel

i.e lblinfo="XXXX";

I hope it ll work
