Question

I have a WPF/MVVM application with a DataGrid on a window. I want to call a method when the user double clicks on a row in the DataGrid.

How can I bind the DblClick event of the DataGrid to my ViewModel?

I prefer to use AttachedCommand Behaviors, which allow you to attach a Command to just about any UI Event

For example,

<Style TargetType="{x:Type DataGridCell}">
    <Setter Property="local:CommandBehavior.Event" Value="MouseDoubleClick" />
    <Setter Property="local:CommandBehavior.Command" Value="{Binding MyDoubleClickCommand" />
    <Setter Property="local:CommandBehavior.CommandParameter" Value="{Binding }" />
</Style>
