I have a next style:
<Style x:Key="Style_MainButtons" TargetType="ToggleButton">
<Setter Property="Width" Value="110" />
<Setter Property="Height" Value="110" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ToggleButton}">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock x:Name="Text" HorizontalAlignment="Center" />
<Image x:Name="Image" Grid.Row="1" />
</Grid>
<ControlTemplate.Triggers>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Because there are few toggle buttons using this style and each have different text and image, so how can I call “TextBlock” and “Image” from style in the next code?
<ToggleButton x:Name="btnHorizontal"
Style="{StaticResource Style_MainButtons}"
Grid.Column="0"
Grid.Row="1"
Checked ="SetVersion"
Unchecked ="SetVersion"
IsChecked="True" >
</ToggleButton>
You can do something like this:
Style
<Style TargetType="ToggleButton">
<Setter Property="Width" Value="110" />
<Setter Property="Height" Value="110" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ToggleButton}">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock x:Name="Text" HorizontalAlignment="Center" Text="{TemplateBinding Content}"/>
<Image x:Name="Image" Grid.Row="1" Source="{TemplateBinding Tag}" />
</Grid>
<ControlTemplate.Triggers>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Usage
<ToggleButton Content="Text" Tag="{Binding Path=Source, Source={StaticResource Image}}"></ToggleButton>
<ToggleButton Content="Another Text" Tag="{Binding Path=Source, Source={StaticResource Image}}"></ToggleButton>
Note: Replace my Tag-Binding with an valid Binding to your actual ImageSource

I'm trying set backcolor for all grid layout in my project using resource dictionary. This is code of file where i modify my grid.
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:Theme">
<SolidColorBrush x:Key="GridBackColor" Color="Red"/>
<Style TargetType="Grid">
<Setter Property="Background" Value="{StaticResource GridBackColor}"/>
<Setter Property="Opacity" Value="0.5"/>
</Style>
</ResourceDictionary>
After set Background property all controls on grid were disappear, but when i set opacity i can only say that all controls are under grid layout and any mouse events not work.
Here how it's look like:
this is my window code.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="10*"/>
<ColumnDefinition Width="125"/>
<ColumnDefinition Width="20"/>
<ColumnDefinition Width="125"/>
<ColumnDefinition Width="10*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="10*"/>
<RowDefinition Height="40"/>
<RowDefinition Height="40"/>
<RowDefinition Height="20"/>
<RowDefinition Height="30"/>
<RowDefinition Height="10*"/>
</Grid.RowDefinitions>
<Label Content="Name" Grid.Column="1" Grid.Row="1" Grid.ColumnSpan="3" FontSize="20"
HorizontalAlignment="Stretch" VerticalAlignment="Center"/>
<TextBox Name="TbName" Grid.Column="1" Grid.Row="2" Grid.ColumnSpan="3" FontSize="20"
HorizontalAlignment="Stretch" />
<Button Content="Add" Name="BtAdd" Grid.Column="1" Grid.Row="4" IsDefault="True"
HorizontalAlignment="Right" VerticalAlignment="Center" Width="100" Click="BtAdd_Click"/>
<Button Content="Close" Name="BtClose" Grid.Column="3" Grid.Row="4" IsCancel="True"
HorizontalAlignment="Left" Width="100" Click="BtClose_Click"/>
</Grid>
When you applied you style globally to all the Grids in your application, the ones used inside other controls will also be affected. For instance take a look at the Window control (from the vs designer, left click on the window > Edit Template > Edit a copy)
<Window.Resources>
<ControlTemplate x:Key="WindowTemplateKey" TargetType="{x:Type Window}">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}">
<Grid>
<AdornerDecorator>
<ContentPresenter/>
</AdornerDecorator>
<ResizeGrip x:Name="WindowResizeGrip" HorizontalAlignment="Right" IsTabStop="false" Visibility="Collapsed" VerticalAlignment="Bottom"/>
</Grid>
</Border>
<ControlTemplate.Triggers>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="ResizeMode" Value="CanResizeWithGrip"/>
<Condition Property="WindowState" Value="Normal"/>
</MultiTrigger.Conditions>
<Setter Property="Visibility" TargetName="WindowResizeGrip" Value="Visible"/>
</MultiTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
<Style x:Key="WindowStyle1" TargetType="{x:Type Window}">
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.WindowTextBrushKey}}"/>
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.WindowBrushKey}}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Window}">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}">
<AdornerDecorator>
<ContentPresenter/>
</AdornerDecorator>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="ResizeMode" Value="CanResizeWithGrip">
<Setter Property="Template" Value="{StaticResource WindowTemplateKey}"/>
</Trigger>
</Style.Triggers>
</Style>
</Window.Resources>
Notice the Grid defined in the Border inside the ControlTemplate.
An easy fix to your issue is to assign a key to your style and assign it to the Grid manually:
<Style TargetType="Grid" x:Key="GridStyle">
<Setter Property="Background" Value="{StaticResource GridBackColor}"/>
<Setter Property="Opacity" Value="0.5"/>
</Style>
To use it:
<Grid Style="{StaticResource GridStyle}">
...
</Grid>
Is it possible to create some sort of base expander style and override the background color of the header in a derived style?
In my application I'm using expanders a lot and I would like to change the background color of the header. I know I could just copy&paste my style and edit the color, but it would be nicer to just create a new style based on the "base style" and setting the header's background color.
But I do not know how to access this color.
It's the color of this line: below I'd like to change (the border in the header): Border Name="border"... I cannot access "border" in the setter of the derived style...
This is my (base) style:
<Style TargetType="Expander" x:Key="ExpanderStyle">
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.ControlDarkBrushKey}}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextColor}}"/>
<Setter Property="Template">
<Setter.Value>
<!-- Control template for expander -->
<ControlTemplate TargetType="Expander" x:Name="exp">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Name="ContentRow" Height="0"/>
</Grid.RowDefinitions>
<Border Name="border" Grid.Row="0" Background="{DynamicResource {x:Static SystemColors.ControlDarkBrushKey}}" BorderThickness="1" CornerRadius="4,4,0,0" >
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="20" />
</Grid.ColumnDefinitions>
<ToggleButton x:Name="tb" FontFamily="Marlett" FontSize="9.75" Background="{DynamicResource {x:Static SystemColors.ControlDarkBrushKey}}" Foreground="Black" Grid.Column="1" Content="u" IsChecked="{Binding Path=IsExpanded,Mode=TwoWay,RelativeSource={RelativeSource TemplatedParent}}" />
<ContentPresenter x:Name="HeaderContent" Grid.Column="0" Margin="4" ContentSource="Header" RecognizesAccessKey="True" />
</Grid>
</Border>
<Border x:Name="Content" Grid.Row="1" BorderThickness="1,0,1,1" CornerRadius="0,0,4,4" >
<ContentPresenter Margin="4" />
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsExpanded" Value="True">
<Setter TargetName="ContentRow" Property="Height" Value="{Binding ElementName=Content,Path=Height}" />
<Setter Property="Content" TargetName="tb" Value="t"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>

I would like to do something like this:
<Style x:Key="ExpanderStyleRed" BasedOn="{StaticResource ExpanderStyle}" TargetType="Expander">
<Setter Property="???" Value="Red"/>
<Style>
Use TemplateBinding:
<Style TargetType="Expander" x:Key="ExpanderStyle">
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.ControlDarkBrushKey}}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextColor}}"/>
<Setter Property="Template">
<Setter.Value>
<!-- Control template for expander -->
<ControlTemplate TargetType="Expander" x:Name="exp">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Name="ContentRow" Height="0"/>
</Grid.RowDefinitions>
<Border Name="border" Grid.Row="0" Background="{TemplateBinding Background}" BorderThickness="1" CornerRadius="4,4,0,0" >
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="20" />
</Grid.ColumnDefinitions>
<ToggleButton x:Name="tb" FontFamily="Marlett" FontSize="9.75" Background="{DynamicResource {x:Static SystemColors.ControlDarkBrushKey}}" Foreground="Black" Grid.Column="1" Content="u" IsChecked="{Binding Path=IsExpanded,Mode=TwoWay,RelativeSource={RelativeSource TemplatedParent}}" />
<ContentPresenter x:Name="HeaderContent" Grid.Column="0" Margin="4" ContentSource="Header" RecognizesAccessKey="True" />
</Grid>
</Border>
<Border x:Name="Content" Grid.Row="1" BorderThickness="1,0,1,1" CornerRadius="0,0,4,4" >
<ContentPresenter Margin="4" />
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsExpanded" Value="True">
<Setter TargetName="ContentRow" Property="Height" Value="{Binding ElementName=Content,Path=Height}" />
<Setter Property="Content" TargetName="tb" Value="t"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style x:Key="ExpanderStyleRed" BasedOn="{StaticResource ExpanderStyle}" TargetType="Expander">
<Setter Property="Background" Value="#2fff0000"/>
</Style>
And then:
<Grid>
<Expander x:Name="expander1" Style="{DynamicResource ExpanderStyle}" Header="Expander" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="7,10,0,0" Height="108">
<TextBlock Width="250" Height="150" TextWrapping="Wrap">

</Expander>
<Expander x:Name="expander2" Style="{DynamicResource ExpanderStyleRed}" Header="Expander" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="12,126,0,0" Height="133">
<TextBlock Width="250" Height="150" TextWrapping="Wrap">
asklsaklsa saaskklsaklas alsaklalkjd

</TextBlock>
</Expander>
</Grid>

In your XAML there are no functions bound to the click event (or any other event). In other words: From the programs point of view there is nothing to do, when any of your buttons get clicked. Is this your problem?
In this case add event handlers and modify the counter in your model accordingly.
I'm using MahApps Metro Styling in WPF and trying to add a style to the TreeViewItem so that the nodes have a folder icon next to them. (http://mahapps.com/MahApps.Metro/)
This is fairly straight forward, all I have to do is override the TreeViewItem header template and add in the image.
The problem is that for some reason the new template is not applied to the first entry in the tree as you can see blow:
All other tree nodes work fine but the first one refuses to have the style applied.
I have confirmed that this is something to do with the MahApps TreeView styling contained in Controls.TreeView.xaml (a new project without MahApps but with the same custom style works as expected) but I cannot see exactly what is going on.
Does anyone have any experience styling TreeViewItems when using MahApps?

I've found the solution :
You need to disable MahApps Metro style like this : Style="{x:Null}"
<TreeView Style="{x:Null}" Grid.Column="0" Grid.Row="1" >
<TreeView.Resources>
<Style TargetType="{x:Type TreeViewItem}">
<Setter Property="HeaderTemplate">
<Setter.Value>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Image Width="20" Height="20" Stretch="Fill" Source="/Resources/folder.png" />
<TextBlock Text="{Binding}" />
</StackPanel>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
</TreeView.Resources>
</TreeView>
