WPF TabItem HeaderTemplate style applying inconsistently - c#

I am getting some strange behavior when I follow the steps provided by other SO answers to how to style tab item headers.
With
<Style TargetType="{x:Type TabItem}">
<Setter Property="HeaderTemplate">
<Setter.Value>
<DataTemplate DataType="{x:Type TabItem}">
<buttons:MyButtonControl Content="{TemplateBinding Content}" />
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
And a tab control as follows
<TabControl>
<TabItem Header="Buttons">
<local:Buttons />
</TabItem>
<TabItem Header="Labels">
<local:Labels />
</TabItem>
</TabControl>
I get a tab control that looks like this
How do I get the style to apply to all tab headers? How do I remove the default tab header style around my datatemplate?
EDIT
If I style the Template rather than the header template the content stops showing up but at least the border goes away on the header that works.
<Style TargetType="{x:Type TabItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<buttons:MyButtonControl Content="{TemplateBinding Content}" />
</DataTemplate>
</Setter.Value>
</Setter>
</Style>

The missing part appears to have been a ContentPresenter with the ContentSource property set to Header.
(Also using a button in the header prevents the tab from being clicked on because the button eats the click event.)
This code displays correctly.
<Style TargetType="TabItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Border>
<ContentPresenter ContentSource="Header">
<ContentPresenter.ContentTemplate>
<DataTemplate>
<TextBlock Text="{TemplateBinding Content}" />
</DataTemplate>
</ContentPresenter.ContentTemplate>
</ContentPresenter>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

Reste telerik Theme after add <Style>

I want to change my WPF & C# code to telerik. Before change i have HeaderContentControl with some Workspaces
My XAML code
<HeaderedContentControl
Content="{Binding Workspaces}"
ContentTemplate="{StaticResource WorkspacesTemplate}"
Style="{StaticResource MainHCCStyle}"
/>
My Resources
<Style x:Key="MainHCCStyle" TargetType="{x:Type HeaderedContentControl}>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type HeaderedContentControl}>
<DockPanel>
<ContentPresenter
ContentSource="Content"
ContentTemplate="{TemplateBinding ContentTemplate}"
/>
</DockPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<DataTemplate x:Key="WorkspacesTemplate">
<TabControl
IsSynchronizedWithCurrentItem="True"
ItemsSource="{Binding}"
ItemTemplate="{StaticResource ClosableTabItemTemplate}"
Margin="4"
/>
</DataTemplate>
After modify code to Telerik my code looks like
My XAML code
<telerik:RadTabbedWindow
Content="{Binding Workspaces}"
ContentTemplate="{StaticResource WorkspacesTemplate}"
telerik:StyleManager.Theme="Office2016"
Style="{StaticResource MainHCCStyle}"
/>
My Resources
<Style x:Key="MainHCCStyle" TargetType="{x:Type telerik:RadTabbedWindow}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type telerik:RadTabbedWindow}">
<DockPanel>
<ContentPresenter
ContentSource="Content"
ContentTemplate="{TemplateBinding ContentTemplate}"
/>
</DockPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<DataTemplate x:Key="WorkspacesTemplate">
<TabControl
IsSynchronizedWithCurrentItem="True"
ItemsSource="{Binding}"
ItemTemplate="{StaticResource ClosableTabItemTemplate}"
Margin="4"
/>
</DataTemplate>
Workspaces wors ok, but Telerik theme doesn't work ( telerik:StyleManager.Theme="Office2016"). Styles only activate if I delete them Style="{StaticResource MainHCCStyle}", however then workspaces doesn't work
The custom Style that targets RadTabbedWindow is overriding its ControlTemplate (via the Template property). This means that the default look and feel of the control is replaced with the Dock panel defined in the Style.
To make this work, set the ContentTemplate of RadTabbedWindow, instead of its Template property.

Custom control and additional style in generic.xaml for it

I have created custom control and a default style for it.
My XAML is simple:
<Style TargetType="{x:Type local:MyControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border CornerRadius="10" BorderThickness="1" Background="Transparent" BorderBrush="Black"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I connect to this style using DefaultStyleKey:
DefaultStyleKey = typeof(MyControl);
And it works. But now I want to create other style for my control. It's because my control can have some modes defined as enums, like:
public enum ControlMode
{
Mode1,
Mode2
}
Now, when my control is in Mode1 I want it to have its default style. But when it's in Mode2 I want it to have another style, like:
<Style TargetType="{x:Type local:MyControl}" x:Key"styleForMode2>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border BorderThickness="1" Background="White" BorderBrush="Black"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
How can I achieve that? DefaultStyleKey works only for type name, so the only thing I came up with is to create another class for my control: MyControlWithMode2. But I'm sure there is more proper way. Right?
(this is library not an application, so I cannot use application's resources)
Assuming your control has a Mode property, the default Style could declare Triggers to set different ControlTemplates for different modes:
<Style TargetType="local:MyControl">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border CornerRadius="10" BorderThickness="1"
Background="Transparent" BorderBrush="Black"/>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="Mode" Value="Mode2">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border BorderThickness="1" Background="White"
BorderBrush="Black"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>

Make use of WindowStyle from resource dictionary and add Buttons to a ControlPresenter in an application

I make use of a resource dictionary with all my styles, icons and more.
Now I'd like to add my own titlebar implementing the title of the solution, my image and a ContentPresenter.
When using the WindowStyle I'd like to add application specific items inside this ContentPresenter, but I don't know how to proceed.
This is my WindowStyle. Inside the Grid you'll find the ContentPresenter I'd like to fill.
<Style TargetType="{x:Type Window}" x:Key="tkDarkWindowStyle">
<Setter Property="AllowsTransparency" Value="True"></Setter>
<Setter Property="Foreground" Value="{StaticResource tkBrandBlueBrush}"></Setter>
<Setter Property="Background" Value="{StaticResource exQuiteDarkBrush}"></Setter>
<Setter Property="WindowStyle" Value="None"></Setter>
<Setter Property="BorderThickness" Value="0"></Setter>
<Setter Property="BorderBrush" Value="{StaticResource exQuiteDarkBrush}"></Setter>
<Setter Property="WindowChrome.WindowChrome">
<Setter.Value>
<WindowChrome CaptionHeight="80" />
</Setter.Value>
</Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Window">
<DockPanel LastChildFill="True">
<Border Background="{TemplateBinding Background}" DockPanel.Dock="Top"
Height="80" x:Name="titlebar">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<DockPanel Grid.Column="0">
<Path DockPanel.Dock="Left" Margin="10" Stretch="Uniform" Fill="{TemplateBinding Foreground}" Data="{Binding Source={StaticResource tkPrimaryLogo}}" VerticalAlignment="Center">
</Path>
<Label Content="{TemplateBinding Title}" Foreground="{TemplateBinding Foreground}" Margin="10" DockPanel.Dock="Left" FontSize="26" VerticalAlignment="Center"/>
</DockPanel>
<ContentPresenter Grid.Column="1"/>
</Grid>
</Border>
<Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="1" Padding="4">
<ContentPresenter/>
</Border>
</DockPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I used the style like this and tried to edit the template and add for example some buttons to the titlebar.
<Window.Resources>
<Style TargetType="{x:Type Window}" x:Key="newWindow" BasedOn="{StaticResource tkDarkWindowStyle}">
<!--here add application specific items? -->
</Style>
</Window.Resources>
How can I use the WindowStyle in my application and add specific items to the space i left at the titlebar?
Since the Window only has a single Content property, it makes no sense to include more than one <ContentPresenter /> element in the ControlTemplate.
You may want to create a custom class that inherits from Window and adds a dependency property called "TitleBarContent" or something. You can then add a ContentControl to the template that binds to this property:
<ContentControl Content="{TemplateBinding TitleBarContent}" />
You can set the value of the dependency property in a style setter as usual:
<Style TargetType="{x:Type local:YourWindowClass}" x:Key="newWindow" BasedOn="{StaticResource tkDarkWindowStyle}">
<Setter Property="TitleBarContent">
<Setter.Value>
<TextBlock>title...</TextBlock>
</Setter.Value>
</Setter>
</Style>

Auto scrolling on TextBox ControlTemplate

I'm using the TextBox below, which in order to apply a DropShadowEffect on its text, uses a ControlTemplate. I managed to get the TextWrapping to work, but once the TextBox fills up, it's content goes out of view. How do I replicate the Auto scrolling to the bottom feature of a native TextBox?
<TextBox TextWrapping="Wrap"
Foreground="LimeGreen"
Background="Black"
Margin="10,40,10,40"
FontSize="40"
HorizontalAlignment="Stretch"
x:Name="Inp"
FontFamily="Courier New"
CaretBrush='LimeGreen'>
<TextBox.Resources>
<Style TargetType="{x:Type TextBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TextBox">
<Grid x:Name="RootElement">
<ScrollViewer>
<ContentPresenter Content="{TemplateBinding Text}">
<ContentPresenter.Effect>
<DropShadowEffect ShadowDepth="4"
Direction="330"
Color="LimeGreen"
Opacity="1"
BlurRadius="5" />
</ContentPresenter.Effect>
<ContentPresenter.Resources>
<Style TargetType="{x:Type TextBlock}">
<Setter Property='TextWrapping'
Value='Wrap' />
</Style>
</ContentPresenter.Resources>
</ContentPresenter>
</ScrollViewer>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</TextBox.Resources>
</TextBox>
This solution is a bit different that what you might expect. I think using the ContentPresenter is the wrong way because in the end you still want the functionality of the TextBox. So my solution focuses on getting rid of the border and focus indicator that mess up the drop shadow effect:
<TextBox x:Name="Inp"
Height="100"
HorizontalAlignment="Stretch"
Background="Transparent"
BorderBrush="Transparent"
BorderThickness="0"
CaretBrush="LimeGreen"
FontFamily="Courier New"
FontSize="40"
Foreground="LimeGreen"
TextWrapping="Wrap">
<TextBox.Effect>
<DropShadowEffect BlurRadius="5"
Direction="330"
Opacity="1"
ShadowDepth="4"
Color="LimeGreen" />
</TextBox.Effect>
<TextBox.FocusVisualStyle>
<Style>
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate/>
</Setter.Value>
</Setter>
</Style>
</TextBox.FocusVisualStyle>
</TextBox>
I set the Background, BorderBrush to be transparent (=> no shadow). I removed the ContentPresenter; it's a 'regular textbox now. And to remove the focus border I set the FocusVisualStyle to an empty Template.

WPF: Styling ContentControl

I would like to create a style that could be applied to any ContentControl which would take the ToolTip and add an image to the ContentControl and apply the tool tip text from the object to the image. I have about a hundred of these that need to be done (in various projects) so being able to create a style would save a lot of typing.
What I am trying to recreate is this (ToolTip text is on the blue 'i' and not the 'Reload Employee Data':
which is accomplished via the following:
<StackPanel Orientation="Horizontal">
<CheckBox Content="Reload Employee Data"
IsChecked="{Binding AdjustmentSettings.ReloadEmployeeData}"
Grid.Row="0"
Grid.Column="0">
</CheckBox>
<Image Source="/DelphiaLibrary;Component/Resources/info.ico"
ToolTip="Check if you want to re-upload ..."/>
</StackPanel>
What I am trying to avoid is creating a new stack panel each time I want to add the blue 'i' with the tool tip text on the 'i' and not on the text of the object.
I was able to create the following that works for a Label:
<!-- Works for just Label -->
<Style x:Key="LabelToolTipStyle"
TargetType="{x:Type Label}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Label">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{TemplateBinding Content}" />
<Image Source="info.ico" ToolTip="{TemplateBinding ToolTip}"/>
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
And I can call this simply by adding the style to the label like so:
<Label Content="First Text" Style="{StaticResource LabelToolTipStyle}" ToolTip="Label with LabelToolTipStyle" />
I then tried to make this more generalized by creating a style targeting ContentControl but obviously doesn't work because this overrides the entire template (in the case of CheckBox control, the checkbox is missing):
<!-- Works on Label but not CheckBox -->
<Style x:Key="ContentToolTipStyle"
TargetType="{x:Type ContentControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ContentControl">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{TemplateBinding Content}" />
<Image Source="info.ico" ToolTip="{TemplateBinding ToolTip}"/>
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Is there a way that I could create a style for ContentControls that would allow me to ADD to the template without redefining the entire template? If it cannot be done to ContentControl I wouldn't be opposed to creating a separate style for each control type but would like to avoid redefining the entire template to do so.
You are almost there. You need to create a custom control template for a ContentControl:
<Style x:Key="ToolTipWrapper" TargetType="{x:Type ContentControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ContentControl}">
<StackPanel Orientation="Horizontal">
<StackPanel.ToolTip>
<ToolTip Visibility="Hidden" />
</StackPanel.ToolTip>
<ContentPresenter />
<Image Source="info.ico" ToolTip="{TemplateBinding ToolTip}" />
</StackPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Then wrap your elements in a ContentControl and apply the style:
<ContentControl Style="{StaticResource ToolTipWrapper}" ToolTip="Hello world">
<CheckBox Content="I am a check box" />
</ContentControl>
What you can't do is to automatically apply the custom style to all "content" controls: you will always need the extra ContentControl wrapped around each element you want to style in this way.
