WPF MVVM: How to close a window

Question

I have a Button that closes my window when it\'s clicked:

Ok

Answer 1

I've tried to resolve this issue in some generic, MVVM way, but I always find that I end up unnecessary complex logic. To achieve close behavior I have made an exception from the rule of no code behind and resorted to simply using good ol' events in code behind:

XAML:

Code behind:

private void OnCloseClicked(object sender, EventArgs e)
{
    Visibility = Visibility.Collapsed;
}

Although I wish this would be better supported using commands/MVVM, I simply think that there is no simpler and more clear solution than using events.
