The EventToCommand behavior allows you to pass event arguments to a command. Set the PassEventArgsToCommand property to true:
<ListBox>
<dxmvvm:Interaction.Behaviors>
<dxmvvm:EventToCommand EventName="MouseDoubleClick"
Command="{Binding EditCommand}"
PassEventArgsToCommand="True"/>
</dxmvvm:Interaction.Behaviors>
</ListBox>
public class MainViewModel : ViewModelBase {
[Command]
public void Edit(MouseButtonEventArgs parameter) {
// ...
}
}
Public Class MainViewModel
Inherits ViewModelBase
<Command>
Public Sub Edit(ByVal parameter As MouseButtonEventArgs)
' ...
End Sub
End Class
You can also use the EventArgsConverter if you need to maintain a clean MVVM pattern.
