推荐答案

在母版页按钮点击事件应该由访问页面内容： -

In master page button click event should access page contents by:-

protected void Button1_Click(object sender, EventArgs e)
{
    TextBox TextBox1 = (TextBox)ContentPlaceHolder1.FindControl("TextBox1");
    if (TextBox1 != null)
    {
        Label1.Text = TextBox1.Text;
    }
}
