'Declaration Public Property LayoutStyle As DockAreaLayoutStyle
public DockAreaLayoutStyle LayoutStyle {get; set;}
When set to Standard, which is the default value, the docked DockAreaPane instances are positioned along the edges of the container.
When set to FillContainer, the innermost DockAreaPane, the last visible DockAreaPane in the DockAreas collection whose DockedState is Docked, fills the remaining space. This means that the dock area pane set to fill the available area may change as controls are docked and undocked since hiding, closing or unpinned all the panes in a dock area hides the associated dock area.
Note: When using FillContainer, if any control has their fill property set to false, there will be no fill pane. Also, since the dock areas implement the Infragistics.Win.UltraWinDock.IDockingArea interface and are designed to be positioned towards the outside of the container, as occurs in Visual Studio, any other docked controls will be positioned above the filled dock area.
