WPF Datagrid Double Click Cell MVVM Design

Question

I have a WPF application that contains a datagrid. It is bound to my List object \"Orders\" shown below.

public class OrderBlock
{
  public Settings setting;         


        

Answer 1

Instead of double-clicking on the cell you may double-click on the grid

In ViewModel

    public ICommand Edit { get; private set; }

 Edit = new RelayCommand(EditUser, x => _isAdmin);



 private static void EditUser(object usr)
    {
        if (!(usr is User))
            return;

        new UserEditorViewModel(usr as User);
    }
