My project has a viewmodel class in which I have inherited RelayCommand and ICommand.

A Command called ExecuteCommand is created in this view model as shown below and is working fine.

public class LoginWindowViewModel:WorkSpaceViewModel
    {  
        RelayCommand _executecommand;        
        public ICommand ExecuteCommand
        {
            get
            {
                if (_executecommand == null)
                {
                   _executecommand = new RelayCommand(param => Execute(),param => CanExecute());
                }
                return _executecommand;
            }
        }        

        public virtual void Execute()
        {            
            MainWindow window = new MainWindow();
            window.Show();            
        }

        public virtual bool CanExecute()
        {
            return true;
        }
    }

My question is, how can I create another command in the same view model and how to use it.

Simple. Just create another ICommand property:

C#

RelayCommand _executecommand2;
public ICommand ExecuteCommand2
{
    get
    {
        if (_executecommand2 == null)
        {
            _executecommand2 = new RelayCommand(param => Execute2(), param => CanExecute2());
        }
        return _executecommand2;
    }
}

public virtual void Execute2()
{
    MainWindow window = new MainWindow();
    window.Show();
}

public virtual bool CanExecute2()
{
    return true;
}

For using it, you can just bind the ICommand property to the Command property of your view's element. Something like:

XML

<Button Command="{Binding ExecuteCommand2}" />
