WPF tabcontrol styling

I've got a UI with a fairly standard look and feel. It has a column of icons on the left side which 开发者_如何学JAVAwhen clicked open a different user control on the right side. Currently I'm using separate controls for the selection icons and the usercontrol containment. I'm having strange focus issues that I am tired of trying to mitigate and am wondering if I could style a tabcontrol to look like my UI (under the assumption a tabcontrol would not have focus issues when navigating tabs).

Here is a screenshot of the basic UI. The styling is mostly about how to get the tabcontrols page selection to look like my column of icons. Anyone want to throw their hat in the ring as to how I might accomplish this with a tabcontrol? My xaml is pretty weak at this point.

<TabControl TabStripPlacement="Left">
    ...
</TabControl>

Then you put the icons in the Header property of the TabItems and the UserControls in the Content property. That will get you about halfway there. If you want the exact same look you'll need to retemplate the TabControl and TabItem by copying the current template (use Blend or ShowMeTheTemplate to copy the current template) and modifying it as needed. But just changing those properties will let you test whether a TabControl gets rid of your focus issues.

Edit: Here's an example template that should be pretty close to your screenshot

<Style TargetType="{x:Type TabItem}">
    <Setter Property="Background" Value="Transparent" />

    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type TabItem}">

                <Border x:Name="PART_Border" Background="{TemplateBinding Background}" BorderThickness="1" BorderBrush="LightGray" Margin="2">
                    <ContentPresenter ContentSource="Header" Margin="2" />
                </Border>

                <ControlTemplate.Triggers>
                    <Trigger Property="IsSelected" Value="True">
                        <Setter TargetName="PART_Border" Property="BorderBrush" Value="Black" />
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

It's basically a copy of the normal TabControl with some Borders added and removed. Hope that helps.

How about templating the TabControl with a DockPanel, and binding the DockPanel.Dock property of the TabPanel to the original TabStripPlacement property as shown?

<Style  TargetType="{x:Type TabControl}" >
    <Setter Property="OverridesDefaultStyle" Value="True" />
    <Setter Property="SnapsToDevicePixels" Value="True" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type TabControl}">
                <DockPanel KeyboardNavigation.TabNavigation="Local" LastChildFill="True">
                    <TabPanel DockPanel.Dock="{TemplateBinding TabStripPlacement}"
                        Name="HeaderPanel"
                        Grid.Row="0"
                        Panel.ZIndex="1" 
                        Margin="0,0,4,1" 
                        IsItemsHost="True"
                        KeyboardNavigation.TabIndex="1"
                        Background="Transparent" />
                    <Border 
                        Name="Border" 
                        Background="Transparent" 
                        BorderBrush="Black" 
                        BorderThickness="1" 
                        CornerRadius="2" >
                        <ContentPresenter 
                            ContentSource="SelectedContent" />
                    </Border>
                </DockPanel>

                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
