How to bind DataGrid Sorting event to Prism ViewModel DelegateCommand

Since Sorting is an event, you cannot bind it directly, but you can use an EventTrigger.

<DataGrid ItemsSource="{Binding ViewModels}"
      <i:EventTrigger EventName="Sorting">
         <i:InvokeCommandAction Command="{Binding ViewModel_SortingCommand}"/>

If you use the legacy blend behaviors shipped with Blend, use this namespace:


If you use the new Microsoft.Xaml.Behaviors.Wpf Nuget package, use this namespace:


If you need to process the event args in your command, set PassEventArgsToCommand to True:

<b:InvokeCommandAction Command="{Binding FavContextMenuEditCmd}" PassEventArgsToCommand="True"/>

Also note, that there is an EventArgsParameterPath property to specify a property in the event args that should be passed to the command and an EventArgsConverter property to use a converter. These are useful to avoid passing UI related types like event args to your view model.
