如何以编程方式从窗口中删除控件？

Question

I have a window with a button in it, and I need to remove it OR not depending on the argument passed to the window:

    public MainWindow(bool removeControl)
    {
        InitializeComponent();
        if (removeControl)
        {
            //code to remove the button
        }
    }

In the XAML file I declare a normal button:

<Button Width="120" Height="25" Content="Click" Name="ClickButton"></Button>

I know this can be done by doing the reverse thing which means add the button depending of the Boolean parameter, but I need to do so.

You can do:

mybutton.Visibility = Visibility.Collapsed;

...or if you really want it to be removed from the "logical tree"...then it all depends what "container"/parent that Button is in, in how you remove it.
