How to preserve the state of the diagram while switching tabs in the WPF Diagram (SfDiagram)?

In the WPF Diagram, you can preserve the state of the Diagram while switching between tabs by using the DiagramViewModel as the DataContext for each tab. The DiagramViewModel class helps maintain and restore the diagram’s state when tabs are switched. Below is a code example demonstrating how to achieve this.

Code Snippet :

<TabControl>
   <TabItem Header="Tab1">
       <TabItem.DataContext>
           <viewmodel:DiagramVM/>
       </TabItem.DataContext>
       <syncfusion:SfDiagram Nodes="{Binding Nodes}"
                             Connectors="{Binding Connectors}"
                                Theme="{Binding Theme}"/>
   </TabItem>
   <TabItem Header="Tab2">
       <TabItem.DataContext>
           <viewmodel:DiagramVM/>
       </TabItem.DataContext>
       <syncfusion:SfDiagram Nodes="{Binding Nodes}"
                             Connectors="{Binding Connectors}"
                             Theme="{Binding Theme}"/>
   </TabItem>
</TabControl>
