推荐答案

MasterPage s = new MasterPage();
Page p = (Page)s.FindControl("pagename");
Label la=(Label) p.FindControl("ControlName");

试试这个...

try this ...

ContentPlaceHolder mpContentPlaceHolder;
TextBox mpTextBox;
mpContentPlaceHolder = (ContentPlaceHolder)Master.FindControl("ContentPlaceHolder1");
if(mpContentPlaceHolder != null)
{
    mpTextBox = (TextBox) mpContentPlaceHolder.FindControl("TextBox1");
    if (mpTextBox != null)
    {
        mpTextBox.Text = "TextBox found!";
    }
}

// Gets a reference to a Label control that not in
// a ContentPlaceHolder
Label mpLabel = (Label) Master.FindControl("masterPageLabel");
if (mpLabel != null)
{
    Label1.Text = "Master page label = " + mpLabel.Text;
}
