How to Change the Background Color of a Symbol in WPF SfDiagram?

In the WPF Diagram, you can change the background color of a symbol that is in the disabled state by defining triggers within the style of the symbol. The IsEnabled property is used to check the symbol’s enabled state. Based on this condition, you can apply the necessary changes to the background color. Here is a code example to show how to achieve this:

Code Snippet

<Style TargetType="Stencil:Symbol">
   <!-- Binding the IsEnabled property with a custom property. -->
   <Setter Property="IsEnabled" Value="{Binding IsSymbolEnabled}"/>
   <Setter Property="Width" Value="100" />
   <Setter Property="Height" Value="110" />
   <Setter Property="Padding" Value="1" />
   <Setter Property="BorderThickness" Value="1" />
   <Setter Property="Background" Value="Transparent" />
   <Setter Property="BorderBrush" Value="Transparent" />



   <!-- DataTrigger to change Background and Cursor when IsEnabled is false -- >
   <Style.Triggers>
       <Trigger Property="IsEnabled" Value="False">
           <Setter Property="Background" Value="Gray" />
           </Trigger>
   </Style.Triggers>
</Style>
