Hello,

I am glad you found that Mike's response was helpful. Let us know if you have any additional questions regarding the UltraWinGrid.

Hi,

You might have to play around with the code a little to get it to look closer to the cells in your grid. But here's some code to change the summary borders and BackColor. 

I used Dotted borders here, since it looks like that's what your cells and rows are using. But if you want no borders are all, you can just changed Dotted to None.

        private void ultraGrid1_InitializeLayout(object sender, Infragistics.Win.UltraWinGrid.InitializeLayoutEventArgs e)
        {
            UltraGridLayout layout = e.Layout;
            UltraGridOverride ov = layout.Override;

            ov.SummaryFooterCaptionVisible = DefaultableBoolean.False;
            ov.BorderStyleSummaryFooter = UIElementBorderStyle.Dotted;
            ov.BorderStyleSummaryValue = UIElementBorderStyle.Dotted;
            ov.SummaryValueAppearance.BackColor = SystemColors.Window;
                
        }
