title: Why Winforms.Button.Text works for DataBinding but not ImageKey?
body: <p>Is there anyone who knows this?</p>
  
  <p>I have been trying this for the last week, and no luck.</p>
  
  <p>Now I can see that once can bind successfully to a Button's Text property, but not its ImageKey property:</p>
  
  <pre><code>myButton.Text = "new text"; // really changes the bound data
  myButton.ImageKey = "new text"; // does NOT change the bound data
  </code></pre>
  
  <p>I use:</p>
  
  <pre><code>myButton.DataBindings.Add ( new Binding ( "ImageKey", this.MyData, "Name", true, DataSourceUpdateMode.OnPropertyChanged ) );
  </code></pre>
  
  <p>Why? What makes the Binding tick/work? I just don't get it.</p>
  
  <p>EDIT:</p>
  
  <p>OK so I defined these for my own derived control:</p>
  
  <pre><code>public event EventHandler ImageKeyChanged;
  
  protected virtual void OnImageKeyChanged ( EventArgs e )
  {
      if ( ImageKeyChanged!= null )
      {
          ImageKeyChanged ( this, e );
      }
  }
  
  [Bindable ( true )]
  public new string ImageKey
  {
      get
      {
          return base.ImageKey;
      }
      set
      {
          base.ImageKey = value;
          this.OnImageKeyChanged ( EventArgs.Empty );
      }
  }
  </code></pre>
  
  <p>It still doesn't work. Is there a tutorial or something on the net, that shows this. It just doesn't work for me.</p>
