Add the Style on your App.xaml, it should work

i could not find answers on SO anywhere - how do i make hover effect for each "item"
i want that when i hover over canvas (data template, positioned inside grid) to change color on both rectangles that are inside canvas - only place where IsMouseOver works is where i set ContentPresenter, and there i can change size of Grid, and thats all. I cannot get IsMouseOver on canvas to change color of rectangles inside. Anyhow, i am just begginer, so, i know something is wrong, ContentPresenter maybe is the one that takes style trigger, i just do not know how to fix this.

You've actually already done it properly, the problem is that you're setting Fill explicitly in the Rectangle declarations:
<Rectangle ... Fill="#5D606D" ...></Rectangle>
<Rectangle ... Fill="#5D606D" ...></Rectangle>
Those fields have precedence over what you've set in your style, remove them and your code works fine.
I have a Menu Item that won't change its background when I put my mouse over it.
<ControlTemplate x:Key="DropItemStyle" TargetType="MenuItem">
<DockPanel HorizontalAlignment="Left" Background="#FF101315" Height="40" Width="250" Margin="-1,-1,0,0">
<Image Source="{Binding Icon, RelativeSource={RelativeSource TemplatedParent}}" Height="15" Width="15" Margin="12,0" VerticalAlignment="Center" />
<Label Content="{TemplateBinding Header}" FontFamily="Segoe UI Semibold" FontSize="14" Foreground="White" VerticalAlignment="Center" Margin="-12,-1,0,0" />
<Image Source="Images/icon_right.png" Visibility="{Binding HasItems, Converter={StaticResource btv}, RelativeSource={RelativeSource TemplatedParent}}" />
<DockPanel.Style>
<Style TargetType="DockPanel">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="#FF1A1D1F" />
<Setter Property="Opacity" Value="0.5" />
<Setter Property="Cursor" Value="Hand" />
</Trigger>
</Style.Triggers>
</Style>
</DockPanel.Style>
</DockPanel>
</ControlTemplate>
<MenuItem Header="Logout" Template="{StaticResource DropItemStyle}" Icon="Images/logoutIcon.png" Click="logoutButtonClick" />
Please edit this if there is any mistakes
Setting Background="#FF101315" on the DockPanel has a greater priority than the trigger's setter. Move it to the Style instead:
<DockPanel HorizontalAlignment="Left" Height="40" Width="250" Margin="-1,-1,0,0">
<!-- Skipped for readability -->
<Style TargetType="DockPanel">
<Setter Property="Background" Value="#FF101315"/>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="#FF1A1D1F" />
<Setter Property="Opacity" Value="0.5" />
<Setter Property="Cursor" Value="Hand" />
</Trigger>
</Style.Triggers>
</Style>
I would like to change the fill of a rectangle based on a Textblock text
My Textblock
<TextBlock Name="lblOk" Text="OK" Foreground="Black" FontSize="20" FontWeight="Medium" />
My Datatrigger:
<Style x:Key="RectangleFill" TargetType="Rectangle">
<Setter Property="Fill" Value="Blue"></Setter>
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName="lblOk, Path=Text}" Value="OK">
<Setter Property="Fill" Value="#FF008C00" />
</DataTrigger>
</Style.Triggers>
</Style>
My Datatrigger doesnt work, seems the Path=Text is wrong. What is the correct Path?
Please check this code, it is working
<Window.Resources>
<Style x:Key="RectangleFill" TargetType="Rectangle">
<Setter Property="Fill" Value="Blue" />
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=lblOk, Path=Text}" Value="OK">
<Setter Property="Fill" Value="Red" />
</DataTrigger>
</Style.Triggers>
</Style>
</Window.Resources>
<StackPanel>
<TextBlock Name="lblOk" Text="OK" Foreground="Black" FontSize="20" FontWeight="Medium" />
<Rectangle Width="100"
Height="50" Style="{StaticResource RectangleFill}">
<Rectangle.Resources>
</Rectangle.Resources>
</Rectangle>
</StackPanel>
My code is working. I had typo mistake as shwon in comment.
<Style x:Key="RectangleFill" TargetType="Rectangle">
<Setter Property="Fill" Value="Blue"></Setter>
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=lblOk, Path=Text}" Value="OK">
<Setter Property="Fill" Value="#FF008C00" />
</DataTrigger>
</Style.Triggers>

I have the following WPF textbox with Style associated with it. Is there any way by which I can push the TextBox.Style into resources so it can be reused?
<TextBox HorizontalContentAlignment="Center" Text="{Binding IpAddress, Mode=TwoWay}" ToolTip="Ip Address of camera">
<TextBox.Style>
<Style TargetType="TextBox" xmlns:sys="clr-namespace:System;assembly=mscorlib">
<Style.Resources>
<VisualBrush x:Key="CueBannerBrush" AlignmentX="Center" AlignmentY="Center" Stretch="None">
<VisualBrush.Visual>
<Label Content="Camera Ip Address" Foreground="Gray" Opacity="0.5" FontStyle="Italic" />
</VisualBrush.Visual>
</VisualBrush>
</Style.Resources>
<Style.Triggers>
<Trigger Property="Text" Value="{x:Static sys:String.Empty}">
<Setter Property="Background" Value="{StaticResource CueBannerBrush}" />
</Trigger>
<Trigger Property="Text" Value="{x:Null}">
<Setter Property="Background" Value="{StaticResource CueBannerBrush}" />
</Trigger>
<Trigger Property="IsKeyboardFocused" Value="True">
<Setter Property="Background" Value="White" />
</Trigger>
</Style.Triggers>
</Style>
</TextBox.Style>
</TextBox>
Create a Resource Dictionary put your style in it and add it to App.xaml
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:metroChart="clr-
>
<Style TargetType="TextBox" >
<Style.Resources>
<VisualBrush x:Key="CueBannerBrush" AlignmentX="Center" AlignmentY="Center" Stretch="None">
<VisualBrush.Visual>
<Label Content="Camera Ip Address" Foreground="Gray" Opacity="0.5" FontStyle="Italic" />
</VisualBrush.Visual>
</VisualBrush>
</Style.Resources>
<Style.Triggers>
<Trigger Property="Text" Value="{x:Static sys:String.Empty}">
<Setter Property="Background" Value="{StaticResource CueBannerBrush}" />
</Trigger>
<Trigger Property="Text" Value="{x:Null}">
<Setter Property="Background" Value="{StaticResource CueBannerBrush}" />
</Trigger>
<Trigger Property="IsKeyboardFocused" Value="True">
<Setter Property="Background" Value="White" />
</Trigger>
</Style.Triggers>
</Style>
and in your App.xaml
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary Source="YourStyleDictionary.xaml"/>
</ResourceDictionary>
</Application.Resources>
This will create a global style applied on all TextBoxes if you just want to use it for specific TextBoxes add a x:Key to your Style
I'm implementing a search textbox; could you please help me with binding to TextBox.Tag?
Style
<Style x:Key="SearchTextBox" TargetType="{x:Type TextBox}">
<Style.Resources>
<VisualBrush x:Key="CueBannerBrush" AlignmentX="Left" AlignmentY="Center" Stretch="None">
<VisualBrush.Visual>
<Label Content="{Binding RelativeSource={RelativeSource Mode=Self}, Path=Tag}" Foreground="{StaticResource SearchTextBox.Foreground}" FontSize="{StaticResource SearchTextBox.FontSize}"/>
</VisualBrush.Visual>
</VisualBrush>
</Style.Resources>
<Setter Property="FontSize" Value="{StaticResource SearchTextBox.FontSize}" />
<Setter Property="Foreground" Value="{StaticResource SearchTextBox.TextForeground}" />
<Setter Property="MinWidth" Value="200" />
<Style.Triggers>
<Trigger Property="Text" Value="{x:Static sys:String.Empty}">
<Setter Property="Background" Value="{StaticResource CueBannerBrush}" />
</Trigger>
<Trigger Property="Text" Value="{x:Null}">
<Setter Property="Background" Value="{StaticResource CueBannerBrush}" />
</Trigger>
<Trigger Property="IsKeyboardFocused" Value="True">
<Setter Property="Background" Value="White" />
</Trigger>
</Style.Triggers>
</Style>
Usage
<TextBox Style="{StaticResource SearchTextBox}" Tag="Search templates" />
How can I get the binding to work?
This article here is extremely similar to yours: WPF Bind to parent property from within nested element using style
Though, it doesn't really give a code sample, so here's some xaml you can use as an alternative to your current approach.
<Style x:Key="SearchTextBox" BasedOn="{StaticResource {x:Type TextBox}}" TargetType="{x:Type TextBox}">
<Style.Setters>
<Setter Property="Tag" Value=""/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Grid>
<ScrollViewer x:Name="PART_ContentHost" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
<TextBlock x:Name="textBlock" Opacity="0.345" Text="{TemplateBinding Tag}" TextWrapping="Wrap" Visibility="Hidden" />
</Grid>
<ControlTemplate.Triggers>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsFocused" Value="False" />
<Condition Property="Text" Value="" />
</MultiTrigger.Conditions>
<Setter Property="Visibility" TargetName="textBlock" Value="Visible" />
</MultiTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style.Setters>
</Style>
And you'll still write your textbox code the same way you already had it:
<TextBox Style="{StaticResource SearchTextBox}" Tag="Search templates" />
