NativeMdiView Class

Presents MDI child windows as a native MDI.

Namespace: DevExpress.XtraBars.Docking2010.Views.NativeMdi

Assembly: DevExpress.XtraBars.v23.2.dll

NuGet Package: DevExpress.Win.Navigation

Declaration

C#

public class NativeMdiView :
    BaseView

VB.NET

Public Class NativeMdiView
    Inherits BaseView

Remarks

MDI child windows can be presented by a DocumentManager either as a native MDI or tabbed UI. To enable a native MDI, create a NativeMdiView object and assign it to the DocumentManager.View property. To use the tabbed UI, create a TabbedView object and assign it to the DocumentManager.View property.

Operations on documents in a NativeMdiView are encapsulated by a INativeMdiViewController object accessible via the NativeMdiView.Controller property.

Example

This example shows how to enable a native MDI for a DocumentManager where MDI child windows are presented as regular windows within a container.
