Specifies the position of a child element that is inside a DockPanel.
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.
The following example creates and uses an instance of DockPanel by using code. The example shows you how to partition space by creating five Rectangle elements and positioning (docking) them inside a parent DockPanel. If you retain the default setting, the final rectangle fills all the remaining unallocated space.
