disable button on masterpage .net 4.0 (c#)

Question

Im trying to disable a button on the masterpage from a content page when certain criteria are met. I can change the text on masterpage buttons using session variables, but IM having a bit of trouble with this latest bit - any hints anyone?

Answer 1

On your Master Page you would have a public function like so:

Click to copy

public void EnableTheButton(Boolean enable) {
  btnTheButton.Enabled = enable;
}

On your content page you would write:

Click to copy

((MyMasterType)this.Master).EnableTheButton(false);
