Call Command from Code Behind

Question

So I\'ve been searching around and cannot find out exactly how to do this. I\'m creating a user control using MVVM and would like to run a command on the \'Loaded\' event.

Answer 1

Try this:

private void UserControl_Loaded(object sender, RoutedEventArgs e)
{
    //Optional - first test if the DataContext is not a MyViewModel
    if( !this.DataContext is MyViewModel) return;
    //Optional - check the CanExecute
    if( !((MyViewModel) this.DataContext).MyCommand.CanExecute(null) ) return;
    //Execute the command
    ((MyViewModel) this.DataContext).MyCommand.Execute(null)
}
