I am trying to make the tabs the same color, regardless of whether it's selected or not, I have triggered and set the color, but it doesnt seem to be working:
<Window.Resources>
<SolidColorBrush x:Key="TabItem.Selected.Background" Color="#424E5A"/>
<SolidColorBrush x:Key="TabItem.Selected.Border" Color="#424E5A"/>
<Style x:Key="TabControlStyle1" TargetType="{x:Type TabControl}">
<Setter Property="Padding" Value="2"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Background" Value="{StaticResource TabItem.Selected.Background}"/>
<Setter Property="BorderBrush" Value="{StaticResource TabItem.Selected.Border}"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabControl}">
<Grid x:Name="templateRoot" ClipToBounds="true" SnapsToDevicePixels="true" KeyboardNavigation.TabNavigation="Local">
<Grid.ColumnDefinitions>
<ColumnDefinition x:Name="ColumnDefinition0"/>
<ColumnDefinition x:Name="ColumnDefinition1" Width="0"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition x:Name="RowDefinition0" Height="Auto"/>
<RowDefinition x:Name="RowDefinition1" Height="*"/>
</Grid.RowDefinitions>
<TabPanel x:Name="headerPanel" Background="#424E5A" Grid.Column="0" IsItemsHost="true" Margin="2,2,2,0" Grid.Row="0" KeyboardNavigation.TabIndex="1" Panel.ZIndex="1"/>
<Border x:Name="contentPanel" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Grid.Column="0" KeyboardNavigation.DirectionalNavigation="Contained" Grid.Row="1" KeyboardNavigation.TabIndex="2" KeyboardNavigation.TabNavigation="Local">
<ContentPresenter x:Name="PART_SelectedContentHost" ContentSource="SelectedContent" Margin="{TemplateBinding Padding}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="TabStripPlacement" Value="Bottom">
<Setter Property="Grid.Row" TargetName="headerPanel" Value="1"/>
<Setter Property="Grid.Row" TargetName="contentPanel" Value="0"/>
<Setter Property="Height" TargetName="RowDefinition0" Value="*"/>
<Setter Property="Height" TargetName="RowDefinition1" Value="Auto"/>
<Setter Property="Margin" TargetName="headerPanel" Value="2,0,2,2"/>
</Trigger>
<Trigger Property="TabStripPlacement" Value="Left">
<Setter Property="Grid.Row" TargetName="headerPanel" Value="0"/>
<Setter Property="Grid.Row" TargetName="contentPanel" Value="0"/>
<Setter Property="Grid.Column" TargetName="headerPanel" Value="0"/>
<Setter Property="Grid.Column" TargetName="contentPanel" Value="1"/>
<Setter Property="Width" TargetName="ColumnDefinition0" Value="Auto"/>
<Setter Property="Width" TargetName="ColumnDefinition1" Value="*"/>
<Setter Property="Height" TargetName="RowDefinition0" Value="*"/>
<Setter Property="Height" TargetName="RowDefinition1" Value="0"/>
<Setter Property="Margin" TargetName="headerPanel" Value="2,2,0,2"/>
</Trigger>
<Trigger Property="TabStripPlacement" Value="Right">
<Setter Property="Grid.Row" TargetName="headerPanel" Value="0"/>
<Setter Property="Grid.Row" TargetName="contentPanel" Value="0"/>
<Setter Property="Grid.Column" TargetName="headerPanel" Value="1"/>
<Setter Property="Grid.Column" TargetName="contentPanel" Value="0"/>
<Setter Property="Width" TargetName="ColumnDefinition0" Value="*"/>
<Setter Property="Width" TargetName="ColumnDefinition1" Value="Auto"/>
<Setter Property="Height" TargetName="RowDefinition0" Value="*"/>
<Setter Property="Height" TargetName="RowDefinition1" Value="0"/>
<Setter Property="Margin" TargetName="headerPanel" Value="0,2,2,2"/>
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="TextElement.Foreground" TargetName="templateRoot" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
</Trigger>
<Trigger Property="IsSelected" Value="True">
<Setter TargetName="templateRoot" Property="Background" Value="#424E5A" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
But as you can see the color is white rather than the blueygrey the rest of my tab sidebar is:
image How can I fix it so the color is always #424E5A
I think you are close, you are just missing that the header is defined in a TabItem, not in TabControl.
Thus you are looking for another style to add, in addition with the one you have already. Something like:
<Style x:Key="TabItemStyle1" TargetType="{x:Type TabItem}">
<Setter Property="HeaderTemplate">
<Setter.Value>
<DataTemplate>
<Border x:Name="grid" Background="{StaticResource TabItem.Selected.Background}">
<ContentPresenter>
<ContentPresenter.Content>
<TextBlock Margin="4" FontSize="15" Text="{TemplateBinding Content}"/>
</ContentPresenter.Content>
</ContentPresenter>
</Border>
<DataTemplate.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type TabItem}},Path=IsSelected}" Value="True">
<Setter TargetName="grid" Property="Background" Value="{StaticResource TabItem.Selected.Background}"/>
</DataTrigger>
</DataTemplate.Triggers>
</DataTemplate>
</Setter.Value>
</Setter>
Hope it helps.
