How do change the Background color on one ListBox item? - Continued #4

1. "The property 'Value' is missing."
   • This error occurred because you used Condition instead of Value within the Trigger. In XAML, triggers use Value to specify the condition for activation.
2. "The property 'Condition' does not exist in XML namespace."
   • This is a direct consequence of using the incorrect property name Condition. It doesn't exist within the relevant XML namespaces for XAML triggers.

• Within the Trigger element, change Condition="True" to Value="True". This accurately sets the condition for the trigger to activate when the IsSelected property of the ListBoxItem is true.
