Hi Kartik,

There's no property setting to do this, but you could do it with a CreationFilter. Here's a sample CreationFilter that seems to work okay:

    public class GroupHeaderCreationFilter : IUIElementCreationFilter
    {
        #region IUIElementCreationFilter Members

        void IUIElementCreationFilter.AfterCreateChildElements(UIElement parent)
        {
            // If this is not a HeaderUIElement, do nothing.
            HeaderUIElement headerElement = parent as HeaderUIElement;
            if (headerElement == null)
                return;

            // If the header has a column or has no group, then it's not a group header,
            // so just bail out.
            if (headerElement.Header.Column != null || headerElement.Header.Group == null)
                return;

            // Get the TextUIElement contained within the header.
            TextUIElement textElement = parent.GetDescendant(typeof(TextUIElement)) as TextUIElement;

            // If we failed to find a TextUIElement, bail out.
            if (textElement == null)
                return;

            // Make the text element fill the ClipRect of the parent element, rather than the
            // entire rect.
            textElement.Rect = parent.ClipRect;

            // Invalidate the area so that it repaints.
            parent.Control.Invalidate(parent.ClipRect);
        }

        bool IUIElementCreationFilter.BeforeCreateChildElements(UIElement parent)
        {
            // Do nothing
            return false;
        }

        #endregion
    }

You just create an instance of this class and assign it to the CreationFilter property of the grid. You only have to do this once, so the Form_Load it a good place for it:

this.ultraGrid1.CreationFilter = new GroupHeaderCreationFilter();
