Thanks Matt

This is what i wanted..thanks once again

I believe that the Office2007RibbonButton was added as a style for the buttons on the ribbon itself to be able to resolve their styles differently by default.  There are no properties to automatically set the region of the button, however.  Fortunately, this is fairly straightforward to implement with the combination of a DrawFilter as well as setting the Region of the button:

 private class DF : IUIElementDrawFilter
{

    #region IUIElementDrawFilter Members

    public bool DrawElement(DrawPhase drawPhase, ref UIElementDrawParams drawParams)
    {
        drawParams.DrawBorders(UIElementBorderStyle.Rounded3, Border3DSide.All);
        return true;
    }

    public DrawPhase GetPhasesToFilter(ref UIElementDrawParams drawParams)
    {
        if (drawParams.Element is UltraButtonUIElement)
            return DrawPhase.BeforeDrawBorders;

        return DrawPhase.None;
    }

    #endregion
}

this.ultraButton1.DrawFilter = new DF();
this.ultraButton1.Region = DrawUtility.CreateBorderRegion(new Rectangle(Point.Empty, this.ultraButton1.Size), UIElementBorderStyle.Rounded3);

 Hi

Have one more query, I m making the button style to "Office2007RibbonButton", the only problem is the button border is not the same as the  buttons on the Ribbon control.

Do you know how do I change the button border to rounded for infragistics button (ultrabutton) ?

Thank you very much for your reply..setting the UseOSTheme property to false did the trick..

Thank you once again.
