Hi Richard,

Summary values on each GroupBy row.

This is pretty easy. What I would do is handle the grid's InitializeGroupByRow event. You can examine the GroupByRow and determine what you want to do and then set the appearance of the SummaryValue on that row.

For example:

        private void ultraGrid1_InitializeGroupByRow(object sender, InitializeGroupByRowEventArgs e)
        {
            if ((int)e.Row.Value == 1)
                e.Row.Rows.SummaryValues[0].Appearance.BackColor = Color.Blue;
        }

• Summary footer row (and it's Summary values).

I don't think there is any simple way to do this. The SummaryValue has an object in the grid that represents it, so there's an appearance for each individual summary value. But there is no such object for the Summary footer row, it's the same for the entire grid. The only way to color this area for just a single row would be to use a DrawFilter.

Also, the Summary footer area you highlight here is comprised of multiple UIElements, so you can't do this by filtering on a single UIElement.

The DrawFilter code is actually not too bad, though. Here's some quick code I whipped up:

        public class SummaryFooterDrawFilter : IUIElementDrawFilter
        {
            #region IUIElementDrawFilter Members

            bool IUIElementDrawFilter.DrawElement(DrawPhase drawPhase, ref UIElementDrawParams drawParams)
            {
                RowsCollection rows = drawParams.Element.GetContext(typeof(RowsCollection)) as RowsCollection;
                if (rows != null)
                {
                    UltraGridGroupByRow groupbyRow = rows.ParentRow as UltraGridGroupByRow;
                    if (groupbyRow != null &&
                        (int)groupbyRow.Value == 1)
                    {
                        drawParams.AppearanceData.BackColor = Color.Red;
                    }                    
                }

                return false;

            }

            DrawPhase IUIElementDrawFilter.GetPhasesToFilter(ref UIElementDrawParams drawParams)
            {
                if (drawParams.Element is SummaryFooterUIElement ||
                    drawParams.Element is SummaryFooterCaptionUIElement)
                {
                    return DrawPhase.BeforeDrawBackColor;
                }
                return DrawPhase.None;
            }

            #endregion
        }
