    Need Help with Component Directives

    I'm making a dropdown button (cause I can't get the one on the
    toolstrip to work correctly for me).

    I'm setting the AutoSize = true; and I'd like it to be ReadOnly. I can
    do all that, using "new" to hide the old property and access the old
    property using base.AutoSize from inside the subclass... etc.

    But what I can't get is the IDE to stop wanting to set the AutoSize
    property. This of course leads to a compiler error because the
    property is readonly. So I comment those lines out of the designer but
    if I touch the control (move it's location, set or delete the text,
    anything really) the designer tries to set those values again and I
    have to go and comment them out... again.

    I know there is a Directive (those statements in brackets that makes
    the IDE stop trying to set a property but I can't find it. There's
    even one to remove it from the Property list, but I can't find that
    either.

    Any help would be great, especially if you could tell me where to find
    all those cute little directives... that'd be awesome.

      First, you should not be hiding the old property. Use the "override"
      keyword and override it.

      They are called "attributes ". You can use either [Browsable(false )] to
      hide the property altogether, or [ReadOnly(true)] to show it, but not
      allow it to be changed in the Designer.

      I'm not sure of the best place to find them. But one place to look is in
      the list of sub-classes for the Attribute class (near the end of the page):
      Attribute Class (System)
      http://msdn.microsoft.com/en-us/library/system.attribute.aspx
      Represents the base class for custom attributes.


      They are sorted by fully-qualified name, so all the System.Componen tModel
      namespace attributes are together.

          Well, some of them (like Button.Image) are not overridable so I have
          to do it the other way. But, the ones I can override I am.

          Ahh! Thank you (and thanks for letting me know what they are called).
          This is my first foray into component crfeation and I'm not up on all
          the terms.
          Any help would be great, especially if you could tell me where to find
          all those cute little directives... that'd be awesome.

          Thank you very much for that. That will be an enormous help.
