Remarks

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

1. Create a collection of grid bands in a ViewModel.

2. Specify a data template that generates bands:

   XAML

   <Window.Resources>
       <DataTemplate x:Key="ColumnTemplate">
           <dxg:GridColumn FieldName="{Binding Path=(dxci:DependencyObjectExtensions.DataContext).FieldName, RelativeSource={RelativeSource Self}}" />
       </DataTemplate>
       <DataTemplate x:Key="MultiColumnBandTemplate">
           <dxg:GridControlBand Header="{Binding Path=(dxci:DependencyObjectExtensions.DataContext).Header, RelativeSource={RelativeSource Self}}" 
                                ColumnsSource="{Binding Path=(dxci:DependencyObjectExtensions.DataContext).ChildColumns, RelativeSource={RelativeSource Self}}" 
                                ColumnGeneratorTemplate="{StaticResource ColumnTemplate}" />
       </DataTemplate>
   </Window.Resources>
   

3. Assign the band collection to the BandsSource property and the band template to the BandGeneratorTemplate property:

   XAML

   <dxg:GridControl ...
                    BandsSource="{Binding Bands}" 
                    BandGeneratorTemplate="{StaticResource MultiColumnBandTemplate}"/>
   

If you have multiple band templates, use the DataControlBase.BandGeneratorTemplateSelector property to specify a template selector that chooses a template based on the band type.
