Hi Vijay,

By "group header" I assume you mean a GroupByRow. Is that right?

If so, then there's a much easier way than using a CreationFilter. Just use the SummaryDisplayArea property.

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            UltraGridLayout layout = e.Layout;
            UltraGridBand band = layout.Bands[0];
            UltraGridOverride ov = layout.Override;

            layout.ViewStyleBand = ViewStyleBand.OutlookGroupBy;
            band.SortedColumns.Add("Int32 1", false, true);

            band.Summaries.Add(SummaryType.Average, band.Columns["Int32 2"]);
            ov.SummaryDisplayArea = SummaryDisplayAreas.InGroupByRows;            
            
        }

Hello,

A possible approach to achieve this might be by using a 'CreationFilter'.

You could read about it at the following link: http://help.infragistics.com/Help/NetAdvantage/WinForms/2012.1/CLR2.0/html/Win_Creation_Filter.html. Here are some topics from our community which could also help you: http://community.infragistics.com/forums/t/34485.aspx, http://forums.infragistics.com/forums/t/47561.aspx http://community.infragistics.com/forums/t/58186.aspx, http://community.infragistics.com/forums/t/9989.aspx and http://community.infragistics.com/forums/t/50234.aspx. The above approach is not so recommended, because it features element's resizing, creating or removing and could lead to some unexpected behaviors.

I believe that I was able to achieve what you are looking for with the following code sample:

    class CF : IUIElementCreationFilter
    {
        public void AfterCreateChildElements(UIElement parent)
        {
            if (parent is GroupByRowUIElement)
            {
                parent.Rect = new Rectangle(parent.Rect.X, parent.Rect.Y - 10, parent.Rect.Width, parent.Rect.Height);
            }
        }

        public bool BeforeCreateChildElements(UIElement parent)
        {
            return false;
        }
    }

Please do not hesitate to ask if something comes up.
