is there a way i can explicitly state the row to be a Summary row when binding the data to the ultragrid?
you can use:
yourDataGridname.DisplayLayout.Bands[0].Summaries.Add ()
you will need an Infragistics calculator. you can select various summary types to be calculated on the column.
hope this helps.
here is a small example:
List<int> nums = new List<int>();
nums.Add(3);
nums.Add(5);
nums.Add(6);
this.ultraGrid1.DataSource = nums;
this.ultraGrid1.DisplayLayout.Bands[0].Summaries.Add("Summary", Infragistics.Win.UltraWinGrid.SummaryType.Sum, ultraGrid1.DisplayLayout.Bands[0].Columns[0], Infragistics.Win.UltraWinGrid.SummaryPosition.UseSummaryPositionColumn);
