How to group all the SymbolViewModels into the same group in the WPF Diagram (SfDiagram)?

In the WPF Diagram, you can group all the SymbolViewModels into the same group by using the GroupMappingName property. This property groups elements into a single SymbolGroup based on the provided property. We have provided the code example for how to achieve this.

Code Snippet:

<Stencil:Stencil x:Name="stencil"
                Grid.Column="0"
                Grid.Row="1"
                GroupMappingName="Key"
                ExpandMode="ZeroOrMore">
   <Stencil:Stencil.SymbolSource>
       <Syncfusion:SymbolCollection>
           <Syncfusion:SymbolViewModel Symbol="Node" Key="Nodes"
                                       SymbolTemplate="{StaticResource NodeTemplate}" />
           <Syncfusion:SymbolViewModel Symbol="Line" Key="Lines"
                                       SymbolTemplate="{StaticResource LineTemplate}" />
       </Syncfusion:SymbolCollection>
   </Stencil:Stencil.SymbolSource>
</Stencil:Stencil>
