Solution 2

I found this code her[^] with google ("asp.net access a control on master page"):

C#

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;
}

Google is free. Learn how to use it.
