PAVCBC,

If you're after grand-total information for data from child rows, you can add a summary to the root band of the grid based on a column in a child band.  To extend Manoj's examples, you would use something like this:

ultragird.DisplayLayout.Bands[0].Summaries.Add(SummaryType.Sum, ultragird.DisplayLayout.Bands[1].Columns["ColumnName"]);

Notice that this adds a summary to band 0 based on a column in band 1.

To have  a summary of  parent rows 

ultragird.DisplayLayout.Bands[0].Summaries.Add(SummaryType.Sum, ultragird.DisplayLayout.Bands[0].Columns["ColumnName"]);

To have the summary for  Child rows

just you have to change the Band[0] as Band[1]

Like :

ultragird.DisplayLayout.Bands[1].Summaries.Add(SummaryType.Sum, ultragird.DisplayLayout.Bands[1].Columns["ColumnName"]);

Hope this would help you

Regards,

Manoj kumar
