| GridSummaryCalculationMode | A mode that specifies by which rows the summary value is calculated. |
Remarks
The GridControl can calculate summaries against selected rows and cells:
Set the DataViewBase.SummaryCalculationMode property to SelectedRows / Mixed to make the GridControl calculate all summaries within its view against selected rows:
<dxg:GridControl x:Name="grid" SelectionMode="Row">
<dxg:GridControl.View>
<dxg:TableView x:Name="view"
SummaryCalculationMode="SelectedRows"
ShowTotalSummary="True" />
</dxg:GridControl.View>
<dxg:GridControl.TotalSummary>
<dxg:GridSummaryItem FieldName="Total" SummaryType="Sum" DisplayFormat="Sum={0:$0.00}" />
</dxg:GridControl.TotalSummary>
<dxg:GridControl.GroupSummary>
<dxg:GridSummaryItem FieldName="Total" SummaryType="Sum" DisplayFormat="Sum={0:$0.00}" />
</dxg:GridControl.GroupSummary>
</dxg:GridControl>
You can create an individual summary for selected rows/cells and set its SummaryItemBase.CalculationMode property to SelectedRows / Mixed:
<dxg:GridControl x:Name="grid" SelectionMode="Row">
<!-- -->
<dxg:GridControl.View>
<dxg:TableView x:Name="view" ShowTotalSummary="True" ShowGroupedColumns="True" />
</dxg:GridControl.View>
<dxg:GridControl.TotalSummary>
<!-- The first summary against selected rows -->
<dxg:GridSummaryItem FieldName="Total" SummaryType="Sum" ShowInColumn="Total"
DisplayFormat="Selection Total=${0:N}" CalculationMode="SelectedRows" />
<!-- The second summary against all rows -->
<dxg:GridSummaryItem FieldName="Total" SummaryType="Sum" ShowInColumn="Total"
DisplayFormat="Total=${0:N}" />
</dxg:GridControl.TotalSummary>
<dxg:GridControl.GroupSummary>
<dxg:GridSummaryItem FieldName="Total" SummaryType="Sum"
DisplayFormat="Grand Total=${0:N}" CalculationMode="SelectedRows" />
</dxg:GridControl.GroupSummary>
</dxg:GridControl>
NOTE
The GridControl in Server Mode or bound to ICollectionView does not calculate summaries for selection.
