WPF Data Grid - Display Data Summaries in Group Footers

This example demonstrates how to display data summaries in group footers.

Implementation

1. Enable the TableView.ShowGroupFooters option.
2. Specify a column that displays the summary. Use the GridSummaryItem.ShowInGroupColumnFooter property to specify the field name of the column.

<dxg:GridControl x:Name="grid" ItemsSource="{Binding}">
    <dxg:GridControl.Columns>
        <dxg:GridColumn FieldName="Text"/>
        <dxg:GridColumn FieldName="Number0"/>
        <dxg:GridColumn FieldName="Number1"/>
        <dxg:GridColumn FieldName="Number2" Fixed="Left"/>
        <dxg:GridColumn FieldName="Group" GroupIndex="0"/>
    </dxg:GridControl.Columns>
    <dxg:GridControl.View>
        <dxg:TableView ShowGroupFooters="True" GroupSummaryDisplayMode="AlignByColumns"/>
    </dxg:GridControl.View>
    <dxg:GridControl.GroupSummary>
        <dxg:GridSummaryItem FieldName="Text" SummaryType="Count" ShowInGroupColumnFooter="Text"/>
        <dxg:GridSummaryItem FieldName="Number0" SummaryType="Sum" ShowInGroupColumnFooter="Number0"/>
        <dxg:GridSummaryItem FieldName="Number1" SummaryType="Sum" ShowInGroupColumnFooter="Number1"/>
        <dxg:GridSummaryItem FieldName="Number2" SummaryType="Max" ShowInGroupColumnFooter="Number2"/>
