Thanks. My button is using the class below and I still see no borders.

   internal class MyButtonUIElement : ButtonUIElement
    {
        public MyButtonUIElement(UIElement parent) : base(parent)
        {
        }

       
        protected override void InitAppearance(ref AppearanceData appearance, ref AppearancePropFlags requestedProps)
        {
            base.InitAppearance(ref appearance, ref requestedProps);
            appearance.BorderColor = Color.Red;
            appearance.BackColor2 = Color.DarkSeaGreen;
        }
    }

 You have to override it on your derived element class. 

I must be missing something here Mike.  If I create a class which inherits ButtonUIElement and then I try to override the ButtonStyle property so that it is both readable and writable then I get a compiler error stating "'Public Overrides Property ButtonStyle() As Infragistics.Win.UIElementButtonStyle' cannot override 'Public Overridable ReadOnly Property ButtonStyle() As Infragistics.Win.UIElementButtonStyle' because they differ by 'ReadOnly' or 'WriteOnly'".

Actually, I've worked it out now (d'oh).  You override the property as readonly and you expose the ability to change the ButtonStyle through a different property or method.  For example:

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinGrid

Public Class TimeEntryNavButton
  Inherits ButtonUIElement

  Public Property StyleOfButton() As Infragistics.Win.UIElementButtonStyle
    Get
      Return _ButtonStyle
    End Get
    Set(ByVal value As Infragistics.Win.UIElementButtonStyle)
      _ButtonStyle = value
    End Set
  End Property

  Public Overrides ReadOnly Property ButtonStyle() As Infragistics.Win.UIElementButtonStyle
    Get
      Return _ButtonStyle
    End Get
  End Property

End Class

Here it is in C#.

 class MyButtonUIElement : ButtonUIElement

{

get{ return buttonStyle; }}

public EMISButtonUIElement(UIElement parent): base (parent)

{

}

}

Hi, rdeslonde.

I have read your post. And I have applied your code in my program. but your code doesn't not work.

Why doesn't your code work in my program? Is there any code that I write any more?

public class CButtomUIElementEx : Infragistics.Win.ButtonUIElement

{
    private UIElementButtonStyle buttonStyle = UIElementButtonStyle.OfficeXPToolbarButton;

    public UIElementButtonStyle StyleOfButton
   {
       get { return buttonStyle; }
       set { buttonStyle = value; } 
    }

    public override UIElementButtonStyle ButtonStyle
   {

       get { return buttonStyle; }
    }

     public CButtomUIElementEx(UIElement parent)
           : base(parent)
    {
    }

}

Perfect!  Thanks for the super-fast reply!

Hi,

There are a number of ways to do this. If you never want the button to draw themed, then the simplest thing to do is override the DrawTheme method and return false.

QUOTING: "My guess is that your button is being drawing using OS Themes. You have to set UseOsThemes on the control to False to turn off themes."

How do you set UseOsThemes to FALSE for a class derived from ButtonUIElement?  I cannot figure this out.

You are right! Thank you for your answer!!
