I believe you need to set the @MasterType Directive on your .aspx page:
<%@ MasterType VirtualPath="myMasterPage.master" %>
Then expose the control you want as a property (in the master page):
public string first1Text
{
get { return first1.Text; }
set { first1.Text = value; }
}
then access the control in the content code behind:
Master.first1Text = "This is my Text!";
I'm not sure how to do code blocks on this forum. Let's see if this looks better.
