Property Value

Type	Description
GridSummaryItemCollection	A collection of group summary items.

Remarks

When you group data against a column, the GridControl displays group summaries in group rows. To add a summary to the GridControl:

1. Create a GridSummaryItem object and assign it to the GroupSummary collection.
2. Specify the FieldName and SummaryType properties to apply the summary:

MainWindow.xaml

<dxg:GridControl AutoGenerateColumns="AddNew" ItemsSource="{Binding Customers}">
    <dxg:GridControl.GroupSummary>
        <dxg:GridSummaryItem FieldName="Visits" SummaryType="Max"/>
    </dxg:GridControl.GroupSummary>
</dxg:GridControl>

The GridSummaryItem objects are summary items. The GroupSummary collection’s methods allow you to add, remove, and access summary items.

You can access a collection of total summary items with the GridControl.TotalSummary property.
