Remarks

The DXGrid allows you to display concise information about groups of rows or individual data columns. For example, you can display the number of records, or maximum value, etc. This is called a summary.

Two summary types are supported: Total Summary and Group Summary. The grid stores its total summary items within the GridControl.TotalSummary collection. Group summary items are stored within the GridControl.GroupSummary collection. Individual summary items are represented by the GridSummaryItem class.
