推荐答案

您可以使用Page.Master.FindControl来访问母版页中的任何控件

例如访问名为"btnSave"的按钮，您可以使用

You can use Page.Master.FindControl to access any control in Master Page

for example to access button named "btnSave", You can Use

(Page.Master.FindControl("btnSave") as Button).Enabled = false;

就是这样.

Thats it.

cp1:
按钮Button1 =(Button)Master.FindControl("Button1");
Button1.Enabled = true;

cp2:
按钮Button1 =(Button)Master.FindControl("Button1");
Button1.Enabled = false;

cp1 :
Button Button1 = (Button)Master.FindControl("Button1");
Button1.Enabled = true;

cp2 :
Button Button1 = (Button)Master.FindControl("Button1");
Button1.Enabled = false;
