I want to set the background property of all the usercontrols of my project.
I tried with
<style TargetType={x:Type UserControl}>
<setter property="Background" Value="Red" />
</style>
It compiles but didn't work.
¿Any Idea?
Thanks!
You can only set a a style to a specific class, so this will work (create a UserControl object, not very useful):
<Window.Resources>
<Style TargetType="{x:Type UserControl}">
<Setter Property="Background" Value="Red" />
</Style>
</Window.Resources>
<Grid>
<UserControl Name="control" Content="content"></UserControl>
</Grid>
But this doesn't (Create a class derived from UserControl):
<Window.Resources>
<Style TargetType="{x:Type UserControl}">
<Setter Property="Background" Value="Red" />
</Style>
</Window.Resources>
<Grid>
<l:MyUserControl Name="control" Content="content"></l:MyUserControl>
</Grid>
What you can do is either explicitly set the style using the Style property:
<Window.Resources>
<Style TargetType="{x:Type UserControl}" x:Key="UCStyle">
<Setter Property="Background" Value="Red" />
</Style>
</Window.Resources>
<Grid>
<l:MyUserControl Name="control" Content="content" Style="{StaticResource UCStyle}"></l:MyUserControl>
</Grid>
or create a style for each derived class, you can use BasedOn to avoid duplicating the style content:
<Window.Resources>
<Style TargetType="{x:Type UserControl}" x:Key="UCStyle">
<Setter Property="Background" Value="Red" />
</Style>
<Style TargetType="{x:Type l:MyUserControl}" BasedOn="{StaticResource UCStyle}" />
</Window.Resources>
<Grid>
<l:MyUserControl Name="control" Content="content"></l:MyUserControl>
</Grid>
I think you're missing some double quotes:
Try this:
<Window.Resources>
<Style TargetType="{x:Type UserControl}">
<Setter Property="Background" Value="Red" />
</Style>
</Window.Resources>
<Grid>
<UserControl Name="control" Content="content"></UserControl>
</Grid>

I want to define the design of my TextBox from static resource, how to apply that?
For now I have:
<TextBox Style="{StaticResource TextBoxHeight }" />
And here Page.Resources:
<Page.Resources>
<Style x:Key="TextBoxHeight" TargetType="{x:Type TextBox}" >
<Setter Property="Height" Value="20"/>
</Style>
<Style x:Key="TextBoxBorder" TargetType="{x:Type Border}" >
<Setter Property="CornerRadius" Value="10"/>
</Style>
</Page.Resources>
But I need that:
<TextBox Style="{StaticResource TextBoxHeight }" Style="{StaticResource TextBoxBorder }" />
But it gives error "The property 'Style' is set multiple times"
You can't set the Style property more than once. And you can't apply a Style with a TargetType of Border to a TextBox. But putting an implicit Border style in the Resources dictionary of the Button style should work:
<Style x:Key="TextBoxHeight1" TargetType="{x:Type TextBox}" >
<Setter Property="Height" Value="20"/>
<Style.Resources>
<Style TargetType="{x:Type Border}">
<Setter Property="CornerRadius" Value="10"/>
</Style>
</Style.Resources>
</Style>
For two TabItems I have two Styles, both use the same ControlTemplate. Now I want styleTabB to show a yellow underline instead of green, but still using the ControlTemplate. How can I modify the Style to accomplish this?

<TabItem Name="tabItem_2" Header="--- Tab B ---" Style="{StaticResource styleTabB}" />
</TabControl>
</Grid>

UPDATE
I tried the proposal of Chris W., but no underline at all is shown:
<ControlTemplate x:Key="ctrlTemplate" TargetType="{x:Type TabItem}">
...
<TextDecoration.Pen>
<Pen Brush="{TemplateBinding Tag}" Thickness="4" />
</TextDecoration.Pen>
...
</ControlTemplate>
<!--Style Tab A-->
<Style x:Key="styleTabA" TargetType="{x:Type TabItem}">
<Setter Property="Tag" Value="Green" />
<Setter Property="Template" Value="{StaticResource ctrlTemplate}" />
</Style>
<!--Style Tab B-->
<Style x:Key="styleTabB" TargetType="{x:Type TabItem}">
<Setter Property="Tag" Value="Yellow" />
<Setter Property="Template" Value="{StaticResource ctrlTemplate}" />
</Style>
You can set the style of the children within the child by targetting particular types. Here all Pen are updated with Yellow color.
<Style x:Key="styleTabB" TargetType="{x:Type TabItem}">
<Style.Resources>
<Style TargetType="{x:Type Pen}">
<Setter Property="Brush" Value="Yellow"></Setter>
</Style>
</Style.Resources>
<Setter Property="Template" Value="{StaticResource ctrlTemplate}" />
</Style>
#CarbineCoder is correct for most instances but for your instance you're right and the error you received from his would be expected since Pen isn't a TargetType. However if we tweak it just a little to hit the actual FrameworkElement of which TextDecorations is a property let's try this...and read the whole thing since the first snippet is just an example explanation.
<Style x:Key="styleTabB" TargetType="{x:Type TabItem}">
<Style.Resources>
<Style TargetType="{x:Type TextBlock}">
<Setter Property="TextDecorations">
<Setter.Value>
<TextDecorationCollection>
<TextDecoration>
<TextDecoration.Pen>
<Pen Brush="Yellow"/>
</TextDecoration.Pen>
</TextDecoration>
</TextDecorationCollection>
</Setter.Value>
</Setter>
</Style>
</Style.Resources>
<Setter Property="Template" Value="{StaticResource ctrlTemplate}" />
</Style>
** *Except that's not going to work because you're hoping for something that you've already provided an explicit property value for to inherit from parent, and it doesn't work that way. How about instead we bring in the handy Tag property (which I abuse all the time) to piggy back in our value and allow a way to talk to our buddy on the inside of that bugger by making some quick edits to your ControlTemplate like;
<!-- In your STYLE Template you would want to add a default setter of;
<Setter Property="Tag" Value="Green"/>
-->
<ControlTemplate x:Key="ctrlTemplate" TargetType="{x:Type TabItem}">
<Grid Margin="0,0,0,0">
<TextBlock Name="_tbTabItemHeaderText"
Text="{TemplateBinding Header}"
Grid.Column="0"
Background="Thistle"
VerticalAlignment="Center"
Margin="3,0,0,3">
<TextBlock.TextDecorations>
<TextDecorationCollection>
<TextDecoration Location="Underline"
PenThicknessUnit="Pixel"
PenOffsetUnit="Pixel"
PenOffset="2">
<TextDecoration.Pen>
<Pen Brush="{TemplateBinding Tag}" Thickness="4" />
</TextDecoration.Pen>
</TextDecoration>
</TextDecorationCollection>
</TextBlock.TextDecorations>
</TextBlock>
</Grid>
</ControlTemplate>
Now we should be able to hit like;
<!-- Style Tab A
: This guy should just keep it green IF you applied the default setter mentioned above to the STYLE template -->
<Style x:Key="styleTabA" TargetType="{x:Type TabItem}">
<Setter Property="Template" Value="{StaticResource ctrlTemplate}" />
</Style>
<!-- Style Tab B
: This guy should turn it Yellow -->
<Style x:Key="styleTabB" TargetType="{x:Type TabItem}">
<Setter Property="Tag" Value="Yellow"/>
<Setter Property="Template" Value="{StaticResource ctrlTemplate}" />
</Style>
I didn't have time to test, but it seems like this should work fine for your scenario. Hope it helps.
I made a little change on Chris W.'s solution and now it's working:
<ControlTemplate x:Key="ctrlTemplate" TargetType="{x:Type TabItem}">
...
<TextDecoration.Pen>
<!--Changed next line from <Pen Brush="{TemplateBinding Tag}" Thickness="4" /> to:-->
<Pen Brush="{Binding Path=Tag, RelativeSource={RelativeSource TemplatedParent}}" Thickness="4" />
</TextDecoration.Pen>
...
</ControlTemplate>
<!--Style Tab A-->
<Style x:Key="styleTabA" TargetType="{x:Type TabItem}">
<Setter Property="Tag" Value="Green" />
<Setter Property="Template" Value="{StaticResource ctrlTemplate}" />
</Style>
<!--Style Tab B-->
<Style x:Key="styleTabB" TargetType="{x:Type TabItem}">
<Setter Property="Tag" Value="Yellow" />
<Setter Property="Template" Value="{StaticResource ctrlTemplate}" />
</Style>
I use a DataGrid (WPF 4.0) control. The style for it is placed in a ResourceDictionary and contains a nested Style element:
<Style x:Key="MyDataGridStyle" TargetType="{x:Type controls:DataGrid}">
<Setter Property="Background" Value="Black"/>
<Setter Property="CellStyle">
<Setter.Value>
<Style TargetType="{x:Type DataGridCell}">
<Setter Property="BorderThickness" Value="0" />
<Setter Property="FocusVisualStyle" Value="{x:Null}" />
</Style>
</Setter.Value>
</Setter>
</Style>
Here, only the Background style is applied. The CellStyle NOT.
It only works when I define the CellStyle directly inside the DataGrid element:
<DataGrid Style="{StaticResource MyDataGridStyle}">
<DataGrid.CellStyle>
<Style TargetType="{x:Type DataGridCell}">
<Setter Property="BorderThickness" Value="0" />
<Setter Property="FocusVisualStyle" Value="{x:Null}" />
</Style>
</DataGrid.CellStyle>
</DataGrid>
Any ideas why?
Update
It seems that there is a problem when mixing styles with PresentationFramework.Aero theme that I have referenced in my ResourceDictionary. If I remove the reference it works!
Doing it the way you suggest works fine for me, I'll paste the code that I used to test your style. (note that I added background = red so I could actually see if the style was being applied)
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<Style x:Key="MyDataGridStyle" TargetType="{x:Type DataGrid}">
<Setter Property="Background" Value="Black"/>
<Setter Property="CellStyle">
<Setter.Value>
<Style TargetType="{x:Type DataGridCell}">
<Setter Property="BorderThickness" Value="0" />
<Setter Property="Background" Value="Red"/>
<Setter Property="FocusVisualStyle" Value="{x:Null}" />
</Style>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<DataGrid Style="{StaticResource MyDataGridStyle}">
<DataGrid.Columns>
<DataGridTextColumn Binding="{Binding Text}"/>
<DataGridTextColumn Binding="{Binding Tag}"/>
</DataGrid.Columns>
<DataGrid.Items>
<TextBlock Text="Item1" Tag="aa"/>
<TextBlock Text="Item2" Tag="bb"/>
<TextBlock Text="Item3" Tag="cc"/>
<TextBlock Text="Item4" Tag="dd"/>
</DataGrid.Items>
</DataGrid>
</Window>

I am beginner on WPF and need your help.
Problem:
I have 4 buttons on the form and need to apply 2 different style on pair of 2 buttons.
Is there any way we can achive this ?
please provide me sample if possible...
Thanks in advance...
You can define named styles and then assign them explicitly to any controls as you wish.
Here is a primer for styling buttons: Getting Started with WPF : Button Control Part 2 – Basic Styling
And here is an example:
<Window x:Class="WpfButtonStyling.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="250" Width="400">
<Window.Resources>
<Style x:Key="ButtonStyle1"
TargetType="{x:Type Button}">
<Setter Property="Foreground"
Value="Red" />
<Setter Property="Margin"
Value="10" />
</Style>
<Style x:Key="ButtonStyle2"
TargetType="{x:Type Button}">
<Setter Property="Foreground"
Value="Blue" />
<Setter Property="Margin"
Value="10" />
</Style>
</Window.Resources>
<Grid>
<StackPanel>
<Button x:Name="FirstButton"
Content="First!"
Style="{StaticResource ButtonStyle1}"/>
<Button x:Name="SecondButton"
Content="Second"
Style="{StaticResource ButtonStyle2}" />
</StackPanel>
</Grid>
</Window>
If someone want to write Style directly in Button, write like below:
<Button>
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="FontFamily" Value="TimesNewRoman" />
<Setter Property="FontSize" Value="50"/>
<Setter Property="Background" Value="Green"/>
</Style>
</Button.Style>
</Button>
Use this Code For different styles for different buttons or any other
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
HorizontalAlignment="Left"
VerticalAlignment="Top">
<Window.Resources>
**<Style x:Key="a" TargetType="{x:Type TextBlock}">
<Setter Property="FontFamily" Value="Verdana" />
<Setter Property="FontSize" Value="50"/>
<Setter Property="Background" Value="Indigo"/>
</Style>
<Style x:Key="b" TargetType="{x:Type TextBlock}">
<Setter Property="FontFamily" Value="Arial"/>
<Setter Property="FontSize" Value="16"/>
</Style>
<Style x:Key="c" TargetType="{x:Type Button}">
<Setter Property="FontFamily" Value="TimesNewRoman" />
<Setter Property="FontSize" Value="50"/>
<Setter Property="Background" Value="Green"/>
</Style>
</Window.Resources>
<Grid>
<TextBlock Margin="26,41,39,0" Style="{StaticResource a}" Height="100" VerticalAlignment="Top">TextBlock with Style1</TextBlock>
<TextBlock Margin="26,77,39,0" Height="32" VerticalAlignment="Top">TextBlock with no Style</TextBlock>
<TextBlock Margin="26,105,67,96" Style="{StaticResource b}">TextBlock with Style2</TextBlock>
<StackPanel Orientation="Horizontal" VerticalAlignment="Top" Margin="26,170,-26,0">
<Button Style="{StaticResource c}">
<Bold >Styles</Bold></Button>
<Button Style="{StaticResource c}">are</Button>
<Button Style="{StaticResource c}">cool</Button>
</StackPanel>
</Grid>
here i declaring the style for both textBlock and button.Use this one..
I want to apply a style to all classes derived from Control. Is this possible with WPF?
The following example does not work. I want the Label, TextBox and Button to have a Margin of 4.
<Window x:Class="WeatherInfo.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Wetterbericht" Height="300" Width="300">
<Window.Resources>
<Style TargetType="Control">
<Setter Property="Margin" Value="4"/>
</Style>
</Window.Resources>
<Grid>
<StackPanel Margin="4" HorizontalAlignment="Left">
<Label>Zipcode</Label>
<TextBox Name="Zipcode"></TextBox>
<Button>get weather info</Button>
</StackPanel>
</Grid>
</Window>
Here's one solution:
<Window.Resources>
<Style TargetType="Control" x:Key="BaseStyle">
<Setter Property="Margin" Value="4"/>
</Style>
<Style BasedOn="{StaticResource BaseStyle}" TargetType="Button" />
<Style BasedOn="{StaticResource BaseStyle}" TargetType="Label" />
<Style BasedOn="{StaticResource BaseStyle}" TargetType="TextBox" />
</Window.Resources>
<Grid>
<StackPanel Margin="4" HorizontalAlignment="Left">
<Label>Zipcode</Label>
<TextBox Name="Zipcode"></TextBox>
<Button>get weather info</Button>
</StackPanel>
</Grid>
This is not possible in WPF. You have a couple of options to help you out:
Create one style based on another by using the BasedOn attribute.
Move the common information (margin, in this case) into a resource and reference that resource from each style you create.
Example of 1
<Style TargetType="Control">
<Setter Property="Margin" Value="4"/>
</Style>
<Style TargetType="TextBox" BasedOn="{StaticResource {x:Type Control}}">
</Style>
Example of 2
<Thickness x:Key="MarginSize">4</Thickness>
<Style TargetType="TextBox">
<Setter Property="Margin" Value="{StaticResource MarginSize}"/>
</Style>
