How to provide an event that is raised on changing a grid layout

This example demonstrates how to provide an event that is raised as soon as a grid layout is changed.

In this example, we have created a GridLayoutHelper class that handles changes of the GridControl object's necessary properties and columns, and raises a custom event in its handlers.

This class can be easily attached to the GridControl object in the following manner:

[XAML]
<dxg:GridControlx:Name="grid"AutoPopulateColumns="True"><dxmvvm:Interaction.Behaviors><local:GridLayoutHelperLayoutChanged="OnGridLayoutChanged"/></dxmvvm:Interaction.Behaviors></dxg:GridControl>
