How to use UserControls as TabbedMDIManager’s children ?

Platform: WinForms |
Control: TabbedMDIManager |
Published Date: April 30, 2011 |
Last Revised Date: July 10, 2014


Normally tabbed-MDI is used in MDI applications where the child forms are the children that get tabbed. But, it is also possible to use tabbed-MDI with UserControls as its children and that are dockable. Please refer the below code snippet which illustrates this:


this.IsMdiContainer = true;


this.userControl11.Parent = this;

this.userControl21.Parent = this;

// Dock the usercontrol11 to the form

this.dockingManager1.DockControl(this.userControl11, this, DockingStyle.Bottom, 200);

// Make userControl11 as other controls parent

this.dockingManager1.DockControl(this.userControl21, this.userControl11, DockingStyle.Tabbed, 200);

// Set the usercontrols to MDI mode

this.dockingManager1.SetAsMDIChild(this.userControl11, true);

this.dockingManager1.SetAsMDIChild(this.userControl21, true);


Me.IsMdiContainer = True


Me.UserControl11.Parent = Me

Me.UserControl21.Parent = Me

' Dock the usercontrol11 to the form

Me.dockingManager1.DockControl(Me.UserControl11, Me, DockingStyle.Bottom, 200)

' Make userControl11 as other controls parent

Me.dockingManager1.DockControl(Me.UserControl21, Me.UserControl11, DockingStyle.Tabbed, 200)

' Set the usercontrols to MDI mode

Me.dockingManager1.SetAsMDIChild(Me.UserControl11, True)

Me.dockingManager1.SetAsMDIChild(Me.UserControl21, True)
