| Type | Description |
|---|---|
| DockPanelCollection | A DockPanelCollection object. |
Remarks
The RootPanels property provides access to the collection of visible panels which are not owned by other panels. This collection includes:
- visible floating panels which are not owned by any other floating panels. The Parent properties of these panels are represented by FloatForm objects.
- visible panels docked to the dock manager’s DockManager.Form. These panels are not owned by other panels and therefore the Parent properties of these panels refer to the DockManager.Form object.
The RootPanels collection doesn’t include panels which belong to other panels and panels which have their DockPanel.Visibility property set to DockVisibility.Hidden and DockVisibility.AutoHide.
To access hidden panels use the DockManager.HiddenPanels collection. The panels which have their auto-hide functionality enabled can be obtained via the DockManager.AutoHideContainers collection.
Use index notation to get the child panels of a specific panel.
Example
The following code demonstrates how to enable the auto hide feature for all root panels residing on the dock manager’s form. Floating panels are not affected by this code.
using DevExpress.XtraBars.Docking;
// ...
int index = 0;
while(index < dockManager1.RootPanels.Count) {
DockPanel rootPanel = dockManager1.RootPanels[index];
// Enable the auto hide functionality if the panel is not floating.
if(rootPanel.FloatForm == null)
rootPanel.Visibility = DockVisibility.AutoHide;
else
index++;
}
