Properties and custom controls.

Posted on 2006-10-30

I am wondering if the following is possible.

I have a control called a ListButton. There is a property called ListWidthStyle. ListWidthStyle is actually a an enum which has

There is another property called ListWidth . What I am trying to do is ONLY allow them to set ListWidth in the properties window of my control if ListWidthStyle is set to CustomWidth. Otherwise it should be greyed out. So pretty much they should only be able to set the ListWidth in the properties window if CustomWidth is selected.

Is this possible?

The most you will be able to do is prevent them from creating an invalid combination (a non-zero ListWidth, and a ListWidthStyle other than ListWidthStyle.CustomWidth):

  ListWidthStyle listWidthStyle;

  [DefaultValue(typeof(ListWidthStyle), "CustomWidth")]
  public ListWidthStyle ListWidthStyle
      return listWidthStyle;
      listWidthStyle = value;

      if (listWidthStyle != ListWidthStyle.CustomWidth)
        listWidth = 0;

  int listWidth;

  public int ListWidth
      return listWidth;
      if (listWidthStyle == ListWidthStyle.CustomWidth)
        listWidth = value;
        throw new ArgumentException("ListWidthStype must be set to CustomWidth");
