Question

Maybe the title is not so clear, but this is what I’m experiencing:

• I have created a base-form which contains an OK and a Cancel button (which is called BaseOkCancelButtonForm)
  This form also has some properties which look like this:

      [Browsable (true)]
      [Category ("Design")]
      [DesignerSerializationVisibility (DesignerSerializationVisibility.Visible)]
      public string OkButtonText
      {
          get
          {
              return btnOk.Text;
          }
          set
          {
              btnOk.Text = value;
          }
      }
  
     [Browsable (true)]
      [Category ("Design")]
      [DefaultValue (true)]
      [DesignerSerializationVisibility (DesignerSerializationVisibility.Visible)]
      public bool OkButtonVisible
      {
          get
          {
              return btnOk.Visible;
          }
          set
          {
              btnOk.Visible = value;
          }
      }
  
      [Browsable (true)]
      [Category ("Design")]
      [DesignerSerializationVisibility (DesignerSerializationVisibility.Visible)]
      public string CancelButtonText
      {
          get
          {
              return btnCancel.Text;
          }
          set
          {
              btnCancel.Text = value;
          }
      }
  
      [Browsable (true)]
      [Category ("Design")]
      [DefaultValue (true)]
      [DesignerSerializationVisibility (DesignerSerializationVisibility.Visible)]
      public bool CancelButtonVisible
      {
          get
          {
              return btnCancel.Visible;
          }
          set
          {
              btnCancel.Visible = value;
          }
      }
  

Now, this is what is happening:
I create a new form which inherits from my BaseOkCancelButtonForm.

When I modify the CancelButtonText property of my inherited form, and I rebuild the project, everything is going as expected: the Text of the Cancel button remains as the text that i’ve set.
However, when I do the same for the CancelButtonVisible property, things go wrong.
When I set the CancelButtonVisible property to false, and I rebuild the project, then VS.NET resets the value of this property back to true. 😕

For one reason or another, the changed value is not persisted by the designer ?
Is this know behaviour ? Am I doing something wrong ?

Answer 1

Hmm, it seems that this does work when I make the CancelButton on my base form protected.
But, I do not want to do that.
Besides, it should not be necessary to do that as well … (And changing the text property of the button does not require the button to be protected, like it should be)…

Weird.
