WPF Data Grid - Create an Event Raised on Layout Changes

This example demonstrates how to create an event that is raised when a user changes the GridControl's layout.

In this example, the GridLayoutHelper class handles changes of the GridControl and GridColumn layout properties and raises a custom event. The event's handler logs layout changes in the Output window:

The following code sample demonstrates how to attach the GridLayoutHelper class to the GridControl:

<dxg:GridControl x:Name="grid" AutoGenerateColumns="AddNew">
    <dxmvvm:Interaction.Behaviors>
	<local:GridLayoutHelper LayoutChanged="GridLayoutHelper_Trigger"/>
    </dxmvvm:Interaction.Behaviors>
</dxg:GridControl>
