Disable button on main page .net 4.0 (C #)

Question

I am trying to disable a button on the main page from the content page when certain criteria are met. I can change the text on the buttons of the main page using session variables, but IM has a bit of a problem with this last bit - any hints from anyone?

Answer 1

On your main page, you will have a public function:

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

On the page of your content you should write:

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

Answer 2

I would add a public method to your main page to do this, and let the content page call it. It can make things a lot easier and more objective.

MasterType , . .

<%@ MasterType virtualpath="~/Masters/Master1.master" %>

masterdata:

public class MasterData
{
    private string _state1;

    public string State1
    {
        get { return _state1; }
        set
        {
            _state1 = value;
            OnDataChanged();
        }
    }

    private string _state2;

    public string State2
    {
        get { return _state2; }
        set
        {
            _state2 = value;
            OnDataChanged();
        }
    }

    public event EventHandler DataChanged;

    private void OnDataChanged()
    {
        if(this.DataChanged != null)
        {
            OnDataChanged(this, EventArgs.Empty);
        }
    }
}
