Assembly: PresentationFramework (in PresentationFramework.dll)
A DockPanel determines its size by analyzing the sizing properties and Dock property value of its child elements. A child element can occupy all the space on the side where it is docked. Child elements that are docked to the Left or Right are granted all the vertical space for their entire width. Child elements that are docked to the Top or Bottom are granted all the horizontal space for their entire height.
