您好


如果要将子方法分配给母版页控件，请在运行时执行.否则，主人会与孩子紧密地联系在一起.

例如，母版页有一个按钮，子页有一个文本框.单击母版页按钮时，它必须填充子文本框.

在子页面上...

Hi


If you want to assign a child method to a master page control, then do it at runtime. Otherwise the master is tightly coupled with the child.

For example the master page has a button and the child page has a text box. When the master page button click then it has to populate the child text box.

at the child page...

protected void Page_Load(object sender, EventArgs e)
 {
     Button button1 = (Button)this.Master.FindControl("Button1");
     button1.Click += new EventHandler(button1_Click);
 }
 protected void button1_Click(object sender, EventArgs e)
 {
     TextBox1.Text = "I am calling this from Master";
 }

在此，母版页在设计时不知道必须调用哪种方法.因此，它与子页面没有紧密耦合.当子页面正在加载时，您将告诉母版页控件执行此操作".这样，您可以使用任何可以绑定到主控件的子控件.

涉及的步骤.

1)使用Master.FindControl方法找到主控件
2)分配一个出现在内容页面中的事件处理程序(委托).

希望对您有帮助

Here the master page doesn''t know at design time which method has to call. So it is not tightly coupled to a child page. When the child page is loading you are telling a master page control ''do this''. In that way you can use any child can bind to master control.

Steps involved.

1) Find the master control using Master.FindControl method
2) Assign an event handler( a delegate) which is present in the content page.

Hope this helps
