DocumentWindow border

Hello,

Could you make a screenshot showing what you see and post a link to that along with some simple XAML that we can paste in a Window to try it and see it here?  Thanks!

Yes, thank you. Just the very basic:

<ribbon:RibbonWindow x:Class="WpfRibbon.RibbonWindow1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:shared="http://schemas.actiprosoftware.com/winfx/xaml/shared"
xmlns:ribbon="http://schemas.actiprosoftware.com/winfx/xaml/ribbon"
xmlns:themes="http://schemas.actiprosoftware.com/winfx/xaml/themes"
xmlns:docking="http://schemas.actiprosoftware.com/winfx/xaml/docking"
ApplicationName="RibbonWindow1" Width="820" Height="620" ResizeMode="CanResizeWithGrip" >
<docking:DockSite Margin="0" BorderThickness="0" Padding="0" >
<docking:Workspace BorderThickness="0" Padding="0" Margin="0" >
<docking:TabbedMdiHost ContainersHaveNewTabButtons="True">
<docking:TabbedMdiContainer>
<docking:DocumentWindow Name="Sess1" Title="Session 1" />
<docking:DocumentWindow Name="Sess2" Title="Session 2" />
</docking:TabbedMdiContainer>
</docking:TabbedMdiHost>
</docking:Workspace>
</docking:DockSite>
</ribbon:RibbonWindow>

Normal window state is fine:

Do not want the left and right border when window is maximized:

Hello,

I believe if you add this under the TabbedMdiHost, it will remove the one pixel border around the tab page content:

<docking:TabbedMdiHost.TabControlStyle>
	<Style TargetType="docking:AdvancedTabControl">
		<Setter Property="BorderThickness" Value="0" />
	</Style>
</docking:TabbedMdiHost.TabControlStyle>

Thanks. That works but is it possible to have that applied to maximized windows only. I like to have the border for normal windows.

Hello,

You'd probably have to dynamically set that property to the Style (store the Style in resources with a x:Key) when the window was maximized to achieve that.

Question is how to detect window was maximized, both for the RibbonWindow and for the case of a floating window?

Well that's true, you couldn't probably change it up properly if you allow floating documents since that root TabbedMdiHost.TabControlStyle property value gets pushed to all TabbedMdiHosts that are on floating MDI areas too.  You'd need to stick with always having it be the standard appearance or always using the Style I mentioned.
