How to show a value which is not bound by the CategoryPath or ValuePath inside the Telerik's RadCartesianChart's Tooltip?

I'm working with a telerik RadCartesianChart. And I'm supposed to show a tooltip which conveys the information about the series inide the chart (such as the date, the value, the title of the series). I was able to show the date and value which were already bound in the CategoryPath and the ValuePath of the chart respectively. But I have no clue how to show the title of the series which belongs to the same data source but not bound by either the CategoryPath or the ValuePath.
Below is what I have done so far.

</telerik:ChartSeriesProvider>
</telerik:RadCartesianChart.SeriesProvider>
</telerik:RadCartesianChart>

To achieve your requirement, you can use the Presenter property of the DataPoint object.
The DataPoint object is the data context passed to the TooltipTemplate.
The Presenter is a property of DataPoint which holds a reference to the series object that hosts the concrete data point.
<telerik:RadCartesianChart.TooltipTemplate>
<DataTemplate>
<TextBlock Text="{Binding Presenter.DataContext.MySeriesNameProperty}" />
</DataTemplate>
</telerik:RadCartesianChart.TooltipTemplate>
You can read a bit more about the DataPoint class in the RadChartView documentation.

I got it working by adding a new property called LegendName to the data source object. And changed the binding path like this <TextBlock Text="{Binding Path=DataItem.LegendName}"/>. Not sure whether this is the proper way but it's working as intended.

ListView Virtualization with FlowDocument as DataTemplate

As a self-set himself the task of writing the messenger (like Telegram, Viber, etc). To display the messages in the chat, I use ListView with FlowDocument as ItemTemplate . This control was chosen because:
1) It is necessary to display images (emoticons);
2) Hyperlinks;
3) It should be possible to select text to copy.
But the application consumes lots of memory, a feeling that FlowDocument not deleted from the memory.
It's my View:

Please help me understand this problem, and I'm sorry for my english!

Unable to resize StackPanel when IDataErrorInfo is triggered

When a TextBox element has an error The custom adorner doesn't resize the StackPanel the Textbox control lies in:
Using DockPanel.Bottom causes the adorner to overlap on the Textbox below.
The code I shamelessly lifted off http://hirenkhirsaria.blogspot.ie/2013/05/wpf-input-validation-using-mvvm.html:
<ControlTemplate.Resources>
<Style x:Key="textblockErrorTooltip" TargetType="TextBlock">
<Setter Property="HorizontalAlignment" Value="Center" />
<Setter Property="VerticalAlignment" Value="Center" />
<Setter Property="FontWeight" Value="Bold" />
<Setter Property="Foreground" Value="White" />
<Setter Property="Margin" Value="10 0 10 0" />
</Style>
</ControlTemplate.Resources>
<DockPanel LastChildFill="true">
<Border Height="Auto" Margin="5,0,0,0" Background="#DC000C" CornerRadius="3" DockPanel.Dock="Right">
<TextBlock Style="{StaticResource textblockErrorTooltip}" Text="{Binding ElementName=customAdorner, Path=AdornedElement.(Validation.Errors)[0].ErrorContent}" />
</Border>
<AdornedElementPlaceholder Name="customAdorner">
<Border BorderBrush="#DC000C" BorderThickness="1.3" />
</AdornedElementPlaceholder>
</DockPanel>
</ControlTemplate>
Sure, I could use Z Index but I don't like it.
Is there a way to cause the StackPanel to resize on error?
I was thinking of adding a ContentTemplate after each Textbox control:
<StackPanel>
<TextBox/>
<ContentTemplate/>
</StackPanel>
<StackPanel>
<TextBox/>
<ContentTemplate/>
</StackPanel>
The ContentTemplate generates an error info DataTemplate which I believe should cause the StackPanel to resize.
But I can't figure out how the binding to (Validation.Errors)[0].ErrorContent} should be done.
My terrible attempt:
<UserControl.Resources>
<DataTemplate x:Key="errorinfo">
<TextBlock>Hello World</TextBlock>
</DataTemplate>
</UserControl.Resources>
<StackPanel Orientation="Horizontal" Grid.Row="4">
<Label Padding="0,0,20,0">Name:</Label>
<StackPanel>
<TextBox Padding="0,0,10,0" Width="150" x:Name="name" Text="{Binding Path=Name, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}"></TextBox>
</StackPanel>
<ContentControl >
<ContentControl.Style>
<Style TargetType="ContentControl">
<Setter Property="ContentTemplate" Value="{x:Null}"/>
<Style.Triggers>
<DataTrigger Binding="{Binding ElementName=name, Path=(Validation.HasError)}" Value="True">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<TextBlock Text="{Binding ElementName=name, Path=(Validation.Errors)[0].ErrorContent}"> </TextBlock>
</DataTemplate>
</Setter.Value>
</Setter>
</DataTrigger>
</Style.Triggers>
</Style>
</ContentControl.Style>
</ContentControl>
</StackPanel>
I can't reuse the datatemplate though!
My question is similar to: WPF- Validation -The validation error message goes behind the other controls because of AdornerDecorator
I just want a different solution.
Any ideas? Thanks

Adorner layers sit separate from the main rendering layers in WPF. A good way to think of an Adorner is simply as a graphical overlay layer which encompasses the shape of the Control it's element tags surround (similar to the behaviour of a Border for example).
You don't need a separate AdornerDecorator for every Control. This means the ideal solution would be to add the AdornerDecorator at the highest level possible such as your Window so that you are always guaranteed an Adorner scope.

I can't believe it! Figured it out myself :D

If you have ideas to improve it please let me know. I'm not sure how efficient it is but it works.

Can you make a style with Buttons like the ones in the picture with an text over the image marked with a color?

I am wondering if its possible in WPF to make a Button style where you have a text, an image and text over the image (upon the image) with a color mark as illustrated on the picture below?
Until now i only got this
<Style TargetType="{x:Type Button}" x:Key="CatProBtn">
<Setter Property="Background" Value="#373737" />
<Setter Property="Foreground" Value="White" />
<Setter Property="FontSize" Value="15" />
<Setter Property="SnapsToDevicePixels" Value="True" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border CornerRadius="4" Background="{TemplateBinding Background}">
<Grid>
<!--<Path x:Name="PathIcon" Width="15" Height="25" Stretch="Fill" Fill="#4C87B3" HorizontalAlignment="Left" Margin="17,0,0,0" Data="F1 M 30.0833,22.1667L 50.6665,37.6043L 50.6665,38.7918L 30.0833,53.8333L 30.0833,22.1667 Z "/>-->
<ContentPresenter x:Name="MyContentPresenter" Content="{TemplateBinding Content}"
HorizontalAlignment="Right" VerticalAlignment="Center"
/>
</Grid>
</Border>
<ControlTemplate.Triggers>
<EventTrigger RoutedEvent="PreviewMouseDown">
<SoundPlayerAction Source="C:\Users\shaban\Downloads\Cash_register_beep_sound_.wav" />
</EventTrigger>
<Trigger Property="Button.IsPressed" Value="True">
<Setter Property="BorderBrush" Value="Transparent" />
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="#E59400" />
<Setter Property="Foreground" Value="White" />
<!--<Setter TargetName="PathIcon" Property="Fill" Value="Black" />-->
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Background" Value="OrangeRed" />
<Setter Property="Foreground" Value="White"/>
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Background" Value="White"/>
<Setter Property="BorderBrush" Value="Wheat"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
....
<Button
Style="{StaticResource CatProBtn}"
Margin="1,1,0,3"
Name="Shaban"
Height="Auto"
Width="Auto"
Grid.Row="1"
Grid.Column="1"
Click="Button_Click">
<StackPanel VerticalAlignment="Bottom" HorizontalAlignment="Center">
<TextBlock Text="Ispinde"></TextBlock>
<Image Source="C:\Users\shaban\Pictures\Picture5.png" Stretch="Uniform"></Image>
<TextBlock Text="Ispinde" HorizontalAlignment="Right"/>
</StackPanel>
</Button>

Inspire from code like this in your Button and modify the values to achieve your desired result.
Use a Grid to layout your content. Superimpose the price on the Image.
<Button MinHeight="50" HorizontalAlignment="Center">
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Text="Title" TextAlignment="Center"/>
<!-- This is where your image is in your code -->
<TextBlock Grid.Row="1" Text="Your
image
here..." FontSize="14" Background="Gray" TextAlignment="Center"/>
<TextBlock Grid.Row="2" Text="Description Description Description" TextAlignment="Center" TextWrapping="Wrap" FontSize="8" MaxWidth="100"/>
<!-- Superimpose price on top of image with some opacity -->
<TextBlock Grid.Row="1" Text="20,00 kr." Background="Yellow" Foreground="Red" HorizontalAlignment="Right" VerticalAlignment="Bottom" Margin="0,0,0,12" Opacity="0.6" FontSize="8"/>
</Grid>
</Button>
Result

You can overlay a Control over another Control by using Grids. It will be something like:
<Button>
<Grid>
<StackPanel VerticalAlignment="Bottom" HorizontalAlignment="Center">
<TextBlock Text="Ispinde"/>
<Image Source="C:\Users\shaban\Pictures\Picture5.png"" Stretch="Uniform"/>
</StackPanel>
<Grid Width="100" Height="40" HorizontalAlignment="Right">
<Grid Background="Red" Opacity="0.6"/>
<TextBlock Foreground="White" Text="Overlay"/>
</Grid>
</Grid>
</Button>

WPF TabItem - Image Binding

Issue
I am trying to bind an Image from my TabItem to my TabControlResource section but I cannot seem to do this. The Header text is fine as the TabItem has a Header attribute but there is nothing I can add my image to.
Code
Here is the whole of my TabControl code:
<TabControl Margin="10" BorderBrush="#c83620" BorderThickness="4" Background="#e37e6e" FontFamily="Segoe UI" FontSize="14" >
<TabControl.Resources>
<Style TargetType="TabItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabItem">
<Border Name="Border" BorderThickness="4,4,4,0" BorderBrush="#c83620" CornerRadius="4,4,0,0" Padding="6,4,6,4" Margin="6,0">
<StackPanel Orientation="Horizontal" Margin="6,4,6,4">
<Image Name="img" Height="15" Width="15" Margin="0,0,4,0" Source="../Images/delete.png" />
<Label Grid.Row="0" Name="Text" Foreground="Black" Content="{TemplateBinding Header}"/>
</StackPanel>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter TargetName="Border" Property="Background" Value="#e37e6e" />
<Setter TargetName="Text" Property="TextBlock.Foreground" Value="White"/>
<Setter TargetName="Text" Property="TextBlock.FontWeight" Value="Bold"/>
<Setter TargetName="Border" Property="Margin" Value="1,1,1,-4"/>
<Setter TargetName="Border" Property="Padding" Value="2"/>
</Trigger>
<Trigger Property="IsSelected" Value="False">
<Setter TargetName="Text" Property="TextBlock.Foreground" Value="#c83620"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</TabControl.Resources>
<TabItem Margin="-3,0,0,0" Header="Login">
</TabItem>
<TabItem Header="General" >
<Label Content="Content goes here..." />
</TabItem>
<TabItem Header="Security" />
<TabItem Header="Details" />
</TabControl>
As you can see from the section below I am binding the content of the label to the header of the TabItem and it works fine:
<Border Name="Border" BorderThickness="4,4,4,0" BorderBrush="#c83620" CornerRadius="4,4,0,0" Padding="6,4,6,4" Margin="6,0">
<StackPanel Orientation="Horizontal" Margin="6,4,6,4">
<Image Name="img" Height="15" Width="15" Margin="0,0,4,0" Source="../Images/delete.png" />
<Label Grid.Row="0" Name="Text" Foreground="Black" Content="{TemplateBinding Header}"/>
</StackPanel>
</Border>
But I want different images for each of the TabItems. Where can i bind the Image to on the TabItem to get the correct image?

You can do that by using other properties of the Template, for example Tag property. So the image binding should look like this.
<Image Name="img" Height="15" Width="15" Margin="0,0,4,0"
Source="{Binding RelativeSource={RelativeSource Mode=TemplatedParent}, Path=Tag.Source}" />
And you should define in the resources all images like that.
<Image x:Key="testImage" Source="/WPFTest;component/Images/Reload.png" />
And bind it to the Tag property of TabItem.
<TabItem Header="General" Tag="{StaticResource testImage}" >
