How to create closed (hidden) panels

The following example shows how to create closed (hidden) panels.

To create closed panels, panel objects are added to the DockLayoutManager.ClosedPanels collection.

In the example, the built-in Closed Panels bar is visible (the DockLayoutManager.ClosedPanelsBarVisibility property is set to Auto). It allows closed panels to be restored on the fly.

<dxdo:DockLayoutManager Margin="12" Name="dockManager1" ClosedPanelsBarVisibility="Auto" dxcore:ThemeManager.ThemeName="Office2007Blue">
    <dxdo:DockLayoutManager.ClosedPanels>
        <!--Create three closed (hidden) panels-->
        <dxdo:LayoutPanel x:Name="paneProperties" Caption="Properties">
            <RichTextBox />
        </dxdo:LayoutPanel>
        <dxdo:LayoutPanel x:Name="paneMessages" Caption="Messages">
            <RichTextBox />
        </dxdo:LayoutPanel>
        <dxdo:LayoutPanel x:Name="paneFindResults" Caption="Find Results">
            <RichTextBox />
        </dxdo:LayoutPanel>
    </dxdo:DockLayoutManager.ClosedPanels>
</dxdo:DockLayoutManager>
