# DockPanel The `DockPanel` control is a `Panel` which lays out its children by "docking" them to the sides or floating in the center. ```markup ``` The `LastChildFill` property means that the last child will fill any remaining space in the panel. The `DockPanel.Dock` attached property is used to control which side an element is docked to. The options are `Left`, `Top` , `Right` and `Bottom`.
