How to enable MDI mode for a DocumentGroup
In this example, the documentGroup1 DocumentGroup is in MDI mode (MDIStyle property is set to MDI ). The DocumentGroup’s panels are displayed as floating windows:
<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>
