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:

   XAML

   <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:

   XAML

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