Answer 1

I looking for editing cell on single click in MVVM and this is an other way to do it.

1. Adding behavior in xaml

2. The EditCellOnSingleClickBehavior class extend System.Windows.Interactivity.Behavior;

   public class EditCellOnSingleClick : Behavior
   {
       protected override void OnAttached()
       {
           base.OnAttached();
           this.AssociatedObject.LoadingRow += this.OnLoadingRow;
           this.AssociatedObject.UnloadingRow += this.OnUnloading;
       }
   
       protected override void OnDetaching()
       {
           base.OnDetaching();
           this.AssociatedObject.LoadingRow -= this.OnLoadingRow;
           this.AssociatedObject.UnloadingRow -= this.OnUnloading;
       }
   
       private void OnLoadingRow(object sender, DataGridRowEventArgs e)
       {
           e.Row.GotFocus += this.OnGotFocus;
       }
   
       private void OnUnloading(object sender, DataGridRowEventArgs e)
       {
           e.Row.GotFocus -= this.OnGotFocus;
       }
   
       private void OnGotFocus(object sender, RoutedEventArgs e)
       {
           this.AssociatedObject.BeginEdit(e);
       }
   }
   

Voila !
