推荐答案

您要使用包含页面中的FindControl方法:

You want to use the FindControl method from the containing page:

Button btn = myUserControl.FindControl("ID_OF_BUTTON") as Button;

if(btn != null)
{
   btn.Text = "Clear";
}

吉姆的解决方案肯定会起作用，但这是另一种解决方法.

在用户控制中:

Jim''s solution will surely work but here is another way to it.

In user control:

public string ButtonLabel
    {
        get
        {
           return ID_OF_BUTTON.Text;
        }
        set
        {
           ID_OF_BUTTON.Text = value;
        }
    }

并在包含页面:

And in the containing page:

NameOfUserControl.ButtonLabel = "Clear";

将该文本写入标签，以便您可以检查label.text，然后
您可以更改
按钮名称为button.text ="DONE"

write that text in a label so that you can check label.text and then
you can change the
button name as button.text="DONE"
