Add Controllers to <Style> from Code-Behind (WPF)

I'm a beginner in WPF. It's hard as hell just so you know!
ok, i have a little style for my application (Actually i copied it, and really don't know whats happening in the middle so...)
i wanted to add some Hyperlinks and Buttons to header of application. so i edited the style and added those from there.
but now i want to change content of those from code-behind, but as you already know that's not happening!
This is my style in Application.Resources:
<BooleanToVisibilityConverter x:Key="bool2VisibilityConverter" />
<Color x:Key="WindowBackgroundColor">#FF2D2D30</Color>
<Color x:Key="HighlightColor">Orange</Color>

so i don't know how change content of Hyperlinks or even i could replace them with Button if that is necessary. just tell me how i could change those content. of course i have to say i tried FindResource but couldn't find that Hyperlinks or Buttons. Thanks in advance guys.

try this:
1. create a new WpfApplication project
2. remove MainWindow.xaml
3. add pages: startup.xaml, page1.xaml or more, and set diff background
4. change StartupUri="startup.xaml" in App.xaml
5. add NavigationWindow Style in App.xaml
<Style TargetType="{x:Type NavigationWindow}">
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.WindowBrushKey}}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.WindowTextBrushKey}}"/>

Undeclared namespace

I've been trying so hard to find an external package to make my WPF Apps in VS 2010 Express Edition look like Metro UI but this version does not support it, so I found this thread: Making WPF applications look Metro-styled, even in Windows 7? (Window Chrome / Theming / Theme) in which the user creates an own Theme. I have tried to adapt his code to my App (namespace WpfApplication1 and window MainWindow, as it is set by default) but I get an error at this part:
<Style x:Key="MainWindowStyle" TargetType="WpfApplication1:MainWindow">
Where it says that WpfApplication1 is an undeclared namespace.
I don't know why this happens since the namespace has the following shape:
namespace WpfApplication1
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
}
}
And this is the whole code from this other guy adapted to my workspace:

Any ideas where it might be failing? Thanks!

When it says the namespace is not declared, it means that is not declared inside XAML. To declare it in XAML you use xmlns:, append the short name and then define the actual namespace, something like this:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:WpfApplication1="clr-namespace:WpfApplication1"
Title="MainWindow" Height="150" Width="350"
>
You can look at above, there are 3 declared namespaces, I added the one you missed and should fix your problem.
Of course you should use some short name instead.

I'm using these for Mimimize, Restore/Maximize and Close the Window.
The problem is that the mouse identifies the button only bottom half of it.
Does'nt raise Click, MouseOver or wont even show the Tooltip from its top half.
In the Template you can see a blue border, Actually that wasn't there before. I kept that to analyse the problem thinking making it transparent might solve. But didn't.

This style works now
<Style TargetType="Button" x:Key="WindowControlButton">

How to show half-transparent layer in ToggleButton?

I have ToggleButton with image inside. When the button is disabled I want half-transparent layer be shown over the button to indicate that the button is disabled.
I thought to use Canvas that will hold image and the rectangle that will be used as half-transparent layer. But that's what I get
Why the rectangle begins from the center of the button? Is there any other, better approach to do it?
<StackPanel>
<ToggleButton Name="MyButton" Height="39" Width="39">
<Canvas>
<Image />
<Rectangle Fill="Black" Width="39" Height="39" Opacity="0.5" >
<Rectangle.Style>
<Style TargetType="{x:Type Rectangle}">
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=MyButton,Path=IsEnabled}" Value="True">
<Setter Property="Visibility" Value="Hidden" />
</DataTrigger>
<DataTrigger Binding="{Binding ElementName=MyButton,Path=IsEnabled}" Value="False">
<Setter Property="Visibility" Value="Visible" />
</DataTrigger>
</Style.Triggers>
</Style>
</Rectangle.Style>
</Rectangle>
</Canvas>
</ToggleButton>
</StackPanel>

Try defining a path to say where to draw the rectangle. Change values to fit in to your button.
eg:
<Path Data=" M0,0 L10,10 M0,10 L10,0" Stretch="Uniform" ></Path>

Try this
<ToggleButton Name="MyButton">
<ToggleButton.Template>
<ControlTemplate TargetType="ToggleButton">
<ControlTemplate.Resources>
<BitmapImage x:Key="Image" UriSource="ImageRoation.png"></BitmapImage>
</ControlTemplate.Resources>
<Grid Height="39" Width="39" Background="Transparent">
<Grid.ColumnDefinitions>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<Border Name="UpperRect" CornerRadius="3" Background="DimGray" Visibility="Hidden" RenderOptions.BitmapScalingMode="HighQuality" Opacity="0.5" BorderBrush="Black" BorderThickness="1" SnapsToDevicePixels="True" UseLayoutRounding="True" Grid.Row="0" Grid.RowSpan="2" Grid.Column="0" Grid.ColumnSpan="2">
<Image Height="7" Width="7" Source="{StaticResource Image}" Stretch="Fill" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="3,3,0,0"></Image>
</Border>
<Border Grid.Row="1" Grid.RowSpan="2" Grid.Column="1" Grid.ColumnSpan="2" Background="DimGray" SnapsToDevicePixels="True"></Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter TargetName="UpperRect" Property="Panel.ZIndex" Value="1"></Setter>
<Setter TargetName="UpperRect" Property="Visibility" Value="Visible"></Setter>
</Trigger>
<Trigger Property="IsEnabled" Value="True">
<Setter TargetName="UpperRect" Property="Panel.ZIndex" Value="0"></Setter>

Undesired clipping when resizing wpf control under certain tresshold

When developing a custom control in WPF I noticed a strange clipping behavior. When I resize the control under a certain minimum boundaries/tress-hold it decides to clip the top 24 pixels of the control for reasons I don't understand.
It would be much appreciated if somebody could explain how i can achieve the desired graphical effect without clipping behavior as illustrated.
The behavior occurs with the following XAML. Note that the XAML is a stripped down to make the it compliant with standard .net 4.0 controls.
<Style x:Key="{ComponentResourceKey ResourceId=DataGridSelectAllButtonStyle, TypeInTargetAssembly={x:Type DataGrid}}" TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Grid>
<Rectangle x:Name="Border" Fill="{DynamicResource {x:Static SystemColors.ControlBrushKey}}" SnapsToDevicePixels="True"/>

So after a few days of fiddling I found the culprit to be GetLayoutClip method. This method returns clipping geometry only if the bounds of the control is smaller than the minimum bounds.
Easiest solution to override this behavior was to make a custom control inherit from the said base control. And to construct new clipping geometry with the extra margin taken into account.
