I need to provide my own summery text for many columns.

How exactly can I achieve this?

Also, can the Summery Caption be removed??

Okay, so if you already know the value of the summary, then the easiest thing to do is to create an ICustomSummaryCalculator class. All you have to do is return the value, or text, that you want to display in the summary.

When you add the summary to the grid you pass in an instance of your class which implements ICustomSummaryCalculator.

Here's some quick sample code I whipped up:

        private void ultraGrid1_InitializeLayout(object sender, InitializeLayoutEventArgs e)
        {
            UltraGridBand band = e.Layout.Bands[0];
            UltraGridColumn column = band.Columns["Column 0"];

            SummarySettings summarySettings = band.Summaries.Add( 
                SummaryType.Custom, 
                new LiteralCustomSummaryCalculator("This is my summary"),
                column, 
                SummaryPosition.UseSummaryPositionColumn,
                column
                );

            summarySettings.DisplayFormat = "{0}";

            column.PerformAutoResize(PerformAutoSizeType.AllRowsInBand);
        }

    internal class LiteralCustomSummaryCalculator : ICustomSummaryCalculator
    {
        private string text;
        public LiteralCustomSummaryCalculator(string text)
        {
            this.text = text;
        }
        #region ICustomSummaryCalculator Members

        void ICustomSummaryCalculator.AggregateCustomSummary(SummarySettings summarySettings, UltraGridRow row)
        {
        }

        void ICustomSummaryCalculator.BeginCustomSummary(SummarySettings summarySettings, RowsCollection rows)
        {
        }

        object ICustomSummaryCalculator.EndCustomSummary(SummarySettings summarySettings, RowsCollection rows)
        {
            return text;
        }

        #endregion
    }

Mike,

Is it possible to apply Value based appearances to the summery row(s)?

Hi,

No, but you can use the SummaryValueChanged event on the grid to apply an appearance to the summary based on it's current Value in code.
