Assembly: PresentationFramework (in PresentationFramework.dll)
If you set the LastChildFill property to true, which is the default setting, the last child element of a DockPanel always fills the remaining space, regardless of any other dock value that you set on the last child element. To dock a child in another direction, you must set the LastChildFill property to false and must also set an explicit dock direction on the last child element.
