Command of ToggleButton does not fire when using a style - wpf

The following ToggleButton works as expected:
<ToggleButton Command="{Binding ToggleCommand}"
RenderOptions.BitmapScalingMode="HighQuality"
ToolTip=".."
VerticalAlignment="Stretch"
Focusable="False" IsChecked="False" Margin="2" Padding="0"
Style="{StaticResource {x:Static ToolBar.ToggleButtonStyleKey}}">
<Image Source="/..;component/Resources/...png" Height="26"/>
</ToggleButton>
When clicked the implementation of ToggleCommand is executed.
Then I decided to use a style like this:
<Style x:Key="ButtonToggle" TargetType="ToggleButton">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<ToggleButton RenderOptions.BitmapScalingMode="HighQuality"
VerticalAlignment="Stretch"
Focusable="False" IsChecked="False" Margin="2" Padding="0"
Style="{StaticResource {x:Static ToolBar.ToggleButtonStyleKey}}">
<Image Source="/..;component/Resources/...png" Height="26"/>
</ToggleButton>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Together with:
<ToggleButton DockPanel.Dock="Right" Command="{Binding ToggleCommand}" ToolTip=".."
Style="{StaticResource ButtonToggle}" />
The display is ok.
The binding with ToggleCommand is ok.
Just when I click the button the implementation of ToggleCommand is not executed.
Can anybody explain why that is?

you need to bind the command of the control in the controlTemplate
add Command="{TemplateBinding Command}" in the togglebutton within the style as:
<Style x:Key="ButtonToggle" TargetType="ToggleButton">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<ToggleButton RenderOptions.BitmapScalingMode="HighQuality"
Command="{TemplateBinding Command}"
VerticalAlignment="Stretch"
Focusable="False" IsChecked="False" Margin="2" Padding="0"
Style="{StaticResource {x:Static ToolBar.ToggleButtonStyleKey}}">
<Image Source="/..;component/Resources/...png" Height="26"/>
</ToggleButton>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

Why cant I write and Display text in my TextBox what is made with an Style and an ControlTemplate?

so I got an TextBox and i made the Style in my Ressource Dictionary like that:
<Style x:Key="TextBoxTemplateBrowser" TargetType="{x:Type TextBox}">
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Border Background="White" CornerRadius="0 0 5 5" BorderBrush="Black" BorderThickness="1">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
And my TextBox himself like that:
<TextBox TextWrapping="Wrap" x:Name="tb" Style="{DynamicResource TextBoxTemplateBrowser}"
Text="{Binding Inhalt, RelativeSource={RelativeSource AncestorType=local:ArtikelBezPanel}, UpdateSourceTrigger=PropertyChanged,Mode=TwoWay}"
TextChanged="TextBox_TextChanged"
Height="{Binding Height, RelativeSource={RelativeSource AncestorType=local:ArtikelBezPanel}, UpdateSourceTrigger=PropertyChanged,Mode=TwoWay}" AcceptsReturn="True" BorderBrush="Black" AcceptsTab="True" VerticalAlignment="Top" BorderThickness="1">
</TextBox>
The Problem what I got now is that, when i try to write in that TextBox I can write anything and there cant be Text displayed what I declare before.
When templating TextBox you need the PART_ContentHost:
eg:
<ScrollViewer Margin="0" x:Name="PART_ContentHost" />
See DOCS for more info!
Replace
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
with
<ScrollViewer Margin="0" x:Name="PART_ContentHost" HorizontalAlignment="Center" VerticalAlignment="Center"/>
and it should work!

Template not working, not showing anything on screen

Any clues what's happening or what I am getting wrong with templates??
Change background of DockPanel, this will use Background property set in Expander in DockPanel. You have set it to Violet.
<DockPanel Background="{TemplateBinding Background}">
Change ToggleButton Content property to <ToggleButton Content="{TemplateBinding Header}".
This will show your Header content of Expander in ToggleButton. You have set it to 'Administrar Cuentas'.
Change control template of your Expander from
<ToggleButton.Template>
<ControlTemplate TargetType="ToggleButton">
<TextBlock Text="{TemplateBinding Content}"/>
</ControlTemplate>
to
<ToggleButton.Template>
<ControlTemplate TargetType="ToggleButton">
<Border BorderBrush="Yellow" BorderThickness="3" CornerRadius="5" Background="{TemplateBinding Background}" Height="24">
<ContentPresenter/>
</Border>
</ControlTemplate>
</ToggleButton.Template>
You are trying to put TextBlock of your Header content(set in XAML) inside TextBlock(template). Now, after change TextBlock of Header content will appear within border. Note here <ContentPresenter/> is pointing to
Header.
These changes are enough. I have also changed Horizontal properties of Expander like :
HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch"

I have touched only your ResourceDictionary, and added background to your second expander.
Output after modifying your styles only.

Changing font size of a button

In my .xaml file these are my resources:
<DataTemplate DataType="{x:Type vm:KeyModel}">
<TextBlock DataContext="{Binding RelativeSource={RelativeSource TemplatedParent}}" FontFamily="Verdana" FontSize="26" Margin="0" >
<Run Text="{Binding Content.Text, Mode=OneWay}" />
</TextBlock>
</DataTemplate>
And here's the style:
<Style x:Key="RoundCorner" TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border CornerRadius="8" BorderBrush="#006AB6" BorderThickness="1" Name="border" Background="{TemplateBinding Background}">
<Grid x:Name="grid" >
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"></ContentPresenter>
</Grid>
</Border>
<ControlTemplate.Triggers>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="FontSize" Value="18"/>
</Style>
And in code I have:
<Button Name="btn_Q" FontSize="8" Content="{Binding KB.Key_Q}" Grid.Column="1" Style="{DynamicResource RoundCorner}"/>
<Button Name="btn_A" Content="{Binding KB.Key_A}" Grid.Column="1" Style="{DynamicResource RoundCorner}"/>
But the FontSize for btn_Q doesn't get to be 8. How can I fix it? I need to make only btn_Q to have a fontsize of 8. All of my other buttons, like btn_A are fine with the style's fontsize.

MenuItem shortcut in ControlTemplate

I've got next makrup:
<Style TargetType="{x:Type MenuItem}">
<Setter Property="MinWidth" Value="65" />
<Setter Property="MinHeight" Value="30" />
<Setter Property="IsTabStop" Value="False" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type MenuItem}">
<Border x:Name="MainBorder" BorderThickness="1" Background="Black">
<TextBlock Margin="5" Text="{TemplateBinding Header}" Foreground="{TemplateBinding Foreground}" />
<Popup x:Name="SubMenuPopup" IsOpen="{Binding Path=IsSubmenuOpen, RelativeSource={RelativeSource TemplatedParent}}" Placement="Right"
AllowsTransparency="True" Focusable="False">
<Border Background="Gray">
<Grid x:Name="SubMenu" Grid.IsSharedSizeScope="True" Background="Transparent">
<StackPanel Margin="0" IsItemsHost="True" KeyboardNavigation.DirectionalNavigation="Cycle" Background="Gray" />
</Grid>
</Border>
</Popup>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
When I create MenuItem somewhere and set it's Header property with "_" symbol - it doesn't create shortcut for this menu item.
Example - letter 'F' is not underlined and shortcut doesn't work.
How to support shortcuts in ControlTemplates in MenuItems?
Thanks.
It is not the complete template but instead of the TextBlock put a ContentPresenter that can recognize access keys:
<ContentPresenter Margin="5" Content="{TemplateBinding Header}" TextBlock.Foreground="{TemplateBinding Foreground}" RecognizesAccessKey="True" />
I suppose the xaml you have pasted here is only part of your implementation, so my solution is onl y a continuation of yours with the access key working...
You can find entire templates just like this one: http://msdn.microsoft.com/en-us/library/ms747082%28v=vs.85%29.aspx
If you want you menu item letter to underline itself of keypress then you have to set the InputGesture on menuitem like this:
<MenuItem Header="_File"
InputGestureText="Ctrl+F"
Commmand={Binding NewFileCommand}/>
But if you want to create shortcut for the menuitem command then you will have to create the commandbindings like below on your window:
<Window.CommandBindings>
<CommandBinding Command="local:MyCommands.NewFile" Executed="NewFile_Executed" />
</Window.CommandBindings>
<Window.InputBindings>
<KeyBinding Key="F" Modifiers="Control" Command="local:MyCommands.NewFile"/>
</Window.InputBindings>

WPF ComboBox Residing in a ListBox Click Event

I have a little issue.
I have a a ListBox that is bound to a list of object. These Objects have a property that can be set. I have in the LIstBox ItemTemplate (a datatemplate) a combobox that is about to the objects property and the combobox has some hardcoded values.
My problem is that when the list box is displayed and I click ont he combo, only the ListBoxItem is selected, The click never makes it to the combobox!
just to give you an idea.

Make sure you don't have IsHitTestVisible="False" on the ComboBox's style. Can you please post here the styles you're using?
I found the problem.
My ItemContainerStyle Template had a rectangle and i guess it was implying zindex somehow. When I expclicity told it to draw the content before the border and it's rectangle, it worked. i just had to add Panel.ZIndex="1" and it worked.
