Hello!

I have attached a file showing the result that I am looking for..

I have two different tables, on eparent (Elements) and one child (Products).

I first create one dataset and then i put and the parent table, then the child table and last of all I create the relation between them. The I add this dataset to the DataSource property of the UltraGrid and do the Binding. The result will be according to the picture on the left side.

I have added some summary code giving me tha original summary appearance in the second Band according to the appearance when it is loaded.

            Me.ug.DisplayLayout.Override.AllowRowSummaries = Infragistics.Win.UltraWinGrid.AllowRowSummaries.False
            Me.ug.DisplayLayout.Override.SummaryDisplayArea = Infragistics.Win.UltraWinGrid.SummaryDisplayAreas.Bottom
            Me.ug.DisplayLayout.Override.SummaryFooterCaptionVisible = Infragistics.Win.DefaultableBoolean.False

            Me.ug.DisplayLayout.Bands(1).Summaries.Add("WeightTotal", Infragistics.Win.UltraWinGrid.SummaryType.Sum, Me.ug.DisplayLayout.Bands(1).Columns("WeightTotal"), Infragistics.Win.UltraWinGrid.SummaryPosition.UseSummaryPositionColumn)
            Me.ug.DisplayLayout.Bands(1).Summaries.Item(1).DisplayFormat = "{0:" & WeightFormat & Chr(32) & "}"
            Me.ug.DisplayLayout.Bands(1).Summaries.Item(1).Appearance.TextHAlign = Infragistics.Win.HAlign.Right

When I later use the groupby option, and dragging the column ModuleID to the groupby area, I would like to have the weighttotal for all the elements in that Module to be summarized according to the position in the image on the right hand side...

Can this behavior be achived?

Thanks for the help!
