Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

Public Property MdiList As Boolean
Dim instance As MenuItem 
Dim value As Boolean 

value = instance.MdiList

instance.MdiList = value

Property Value

Type: System.Boolean
true if a list of the MDI child windows is displayed in this menu item; otherwise, false. The default is false.

When a menu item is selected to display an MDI child window list, the list is displayed as a submenu of the menu item. Only forms that are defined as MDI child forms are displayed in the window list. Only nine child windows can be displayed at a time. If there are more than nine child windows displayed, a "More Windows..." menu item is displayed at the end of the window list. Clicking this menu item displays a dialog box with a complete list of the child windows that are currently active.

The following code example creates a MenuItem that is used to display the list of currently open MDI child forms in an MDI form.

Public Sub SetMDIList()
    ' Create the MenuItem to be used to display an MDI list. 
    Dim menuItem1 As New MenuItem()
    ' Set this menu item to be used as an MDI list.
    menuItem1.MdiList = True 
End Sub
