Remarks

You can define total summaries in a ViewModel and display them in the GridControl. To do this, follow the steps below:

  1. Create a collection of total summaries in a ViewModel.
  2. Specify a data template that generates summaries:

    <Window.Resources>
        <DataTemplate x:Key="SummaryTemplate">
            <ContentControl>
                <dxg:GridSummaryItem FieldName="{Binding Path=(dxci:DependencyObjectExtensions.DataContext).FieldName, RelativeSource={RelativeSource Self}}"
                                     SummaryType="{Binding Path=(dxci:DependencyObjectExtensions.DataContext).Type, RelativeSource={RelativeSource Self}, Converter={StaticResource SummaryTypeConverter}}"/>
            </ContentControl>
        </DataTemplate>
    </Window.Resources>
    
  3. Assign the total summary collection to the TotalSummarySource property and the summary template to the TotalSummaryGeneratorTemplate property:

    <dxg:GridControl ...
                     TotalSummarySource="{Binding TotalSummary}"
                     TotalSummaryGeneratorTemplate="{StaticResource SummaryTemplate}">
        <dxg:GridControl.View>
            <dxg:TableView ShowTotalSummary="True"/>
        </dxg:GridControl.View>
    </dxg:GridControl>
