How can a WPF StackPanel fill vertically from bottom to top?

Question

I need to be able to fill a stackpanel with buttons but the buttons must appear at the bottom of the stackpanel first and populate upwards<

Answer 1

Another alternative is to use a DockPanel instead.

Just set the LastChildFill to false on the DockPanel.

Then set the attached Dock property to each button you are adding to Bottom before adding to the DockPanel.

example :

            var button = new Button();
            DockPanel.SetDock(button, Dock.Bottom);
