Declaration

Public Class DocumentGroup
    Inherits TabbedGroup

Remarks

DocumentGroup objects are used within the DockLayoutManager to create a tabbed or MDI interface for your documents. Individual pages in a DocumentGroup are represented by DocumentPanel objects.

To switch between the tabbed and MDI styles, use the DocumentGroup.MDIStyle property.

In MDI mode, it's possible to:

• set the location and size of child panels via the DocumentPanel.MDILocation and DocumentPanel.MDISize properties.
• maximize, minimize or restore a specific child panel via a corresponding method provided by the DockLayoutManager.MDIController object.
• tile child panels vertically or horizontally via the methods provided by the DockLayoutManager.MDIController object.

Example 1

This example shows how to create a DocumentGroup with two tabs, represented by DocumentPanel objects.

<dxdo:DocumentGroup x:Name="documentGroup1" ItemHeight="2*" SelectedTabIndex="1">
    <dxdo:DocumentPanel x:Name="document1" Caption="Document 1">
        <RichTextBox />
    </dxdo:DocumentPanel>
    <dxdo:DocumentPanel x:Name="document2" Caption="Document 2">
        <RichTextBox />
    </dxdo:DocumentPanel>
</dxdo:DocumentGroup>

Example 2

In this example, MDI mode is enabled for a DocumentGroup via the MDIStyle property. In this mode, the DocumentGroup's panels are represented as floating windows.

The following image shows the result:

<dxdo:DocumentGroup x:Name="documentGroup1" ItemWidth="2*" MDIStyle="MDI">
    <dxdo:DocumentPanel x:Name="document1" Caption="Document 1" MDISize="200,100" >
        <RichTextBox/>
    </dxdo:DocumentPanel>
    <dxdo:DocumentPanel x:Name="document2" Caption="Document 2" MDISize="200,100" MDILocation="50,120" >
        <RichTextBox/>
    </dxdo:DocumentPanel>
</dxdo:DocumentGroup>
