layoutgroup tab headers on the left

Hi Lymber,

Thank you for your inquiry.

As for DXLayoutControl LayoutGroup, you can customize the LayoutGroup.TabsStyle property to accomplish this task in the following manner:

	
[XAML]
<dxlc:LayoutGroup View="Tabs">
                <dxlc:LayoutGroup.TabsStyle>
                    <Style TargetType="dx:DXTabControl">
                        <Setter Property="View">
                            <Setter.Value>
                                <dx:TabControlMultiLineView HeaderLocation="Left"/>
                            </Setter.Value>
                        </Setter>
                    </Style>
                </dxlc:LayoutGroup.TabsStyle>
                <dxlc:LayoutGroup Header="Header 1"/>
            </dxlc:LayoutGroup>

As for DXDocking DocumentGroup, set the DocumentGroup.CaptionLocation property. For instance:

	
[XAML]
<dxdo:DocumentGroup CaptionLocation="Left">
                    <dxdo:DocumentPanel Caption="Header1"/>
                </dxdo:DocumentGroup>
