how do make a letter pop out of the border?
I want to express it like this picture
I wrote a letter in the text on Border,
The letters are covered like in the picture.
Can you make this stick out like the picture below?
How can solve this?
this is my xaml code

If you put the textblock in a canvas, that will not clip.

<TextBlock

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.

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.

collapsed a ListItem from a listView

and some of the data will collapsed. (and rest of the data will go up) for any list view Item

You should set the ItemContainerStyle for the targettype ListViewItem instead of targeting your item content (StackPanel).
In Resources section, define your style
<Style x:Key="ShowHideStyle" TargetType="ListViewItem">
...
</Style>
Then use it
<ListView ItemContainerStyle="{StaticResource ShowHideStyle}" .../>
Ofcourse, I assume that your converter/trigger thing is actually working and you just have the problem of properly hiding the whole list entry.

Put the StackPanel in an Expander and apply the style to the latter.
<ListView x:Name="LV" ItemsSource= "{Binding Lggv}" SelectionChanged="dataGridData_SelectionChanged"
ItemContainerStyle="{StaticResource ListViewItemStyle}">
<ListView.ItemTemplate>
<DataTemplate x:Name="DT" >
<Expander Header="..." Style="{StaticResource ShowHideStyle}">
<StackPanel x:Name="LVSP" DataContextChanged="LVSP_DataContextChanged" SourceUpdated="LVSP_SourceUpdated">
<Border...></Border...>
<Grid...></Grid...>
</StackPanel>
</Expander>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
Instead of setting the Visbility property to Collapsed/Visible you set the IsExpanded property of the Expander to false/true:
<Style x:Key="ShowHideStyle" TargetType="Expander" >
<Style.Setters>
<Setter Property="IsExpanded" Value="False" />
</Style.Setters>
<Style.Triggers>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Value="True">
<Condition.Binding>
<MultiBinding Converter="{StaticResource V_converter }">
<Binding Path="Type"></Binding>
<Binding Path="NodeID"></Binding>
<Binding Path="TLV"></Binding>
</MultiBinding>
</Condition.Binding>
</Condition>
</MultiDataTrigger.Conditions>
<MultiDataTrigger.Setters>
<Setter Property="IsExpanded" Value="True" />
</MultiDataTrigger.Setters>
</MultiDataTrigger>
</Style.Triggers>
</Style>

DataBinding ListView creating components if a certain condition is met

I am working on a C# WPF project and I have a list view which uses data binding and a collection view.
Below is how my ListView is currently populated.
<ListView HorizontalAlignment="Left" Margin="547,12,0,41" Name="lstCallLogInformation" Width="320">
<ListView.Style>
<Style TargetType="ListView">
<Style.Triggers>
<Trigger Property="HasItems" Value="False">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListView">
<TextBlock Text="No items in your devices call log" FontWeight="Bold" HorizontalAlignment="Center" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
</ListView.Style>
<ListView.GroupStyle>
<GroupStyle>
<GroupStyle.ContainerStyle>
<Style TargetType="{x:Type GroupItem}">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Expander IsExpanded="True">
<Expander.Header>
<StackPanel Orientation="Horizontal">
<TextBlock FontWeight="Bold" Foreground="Gray" Text="{Binding Name}" VerticalAlignment="Bottom" />
</StackPanel>
</Expander.Header>
<ItemsPresenter />
</Expander>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</GroupStyle.ContainerStyle>
</GroupStyle>
</ListView.GroupStyle>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="Control.HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>
<ListView.ItemTemplate>
<DataTemplate>
<DockPanel Style="{StaticResource onmouseover}">
<StackPanel HorizontalAlignment="Stretch" Orientation="Horizontal" Tag="{Binding logID}">
<Image Height="30" Source="{Binding base64ImageString, Converter={StaticResource ImageConverter}}" Width="30" />
<StackPanel Margin="10" Orientation="Vertical">
<TextBlock FontWeight="Bold" Text="{Binding contactNameOrPhoneNumber}" />
<StackPanel HorizontalAlignment="Stretch" Orientation="Horizontal">
<TextBlock HorizontalAlignment="Left" Text="{Binding dateString}" />
<TextBlock Margin="15, 0, 0, 0" Text="Duration: " />
<TextBlock HorizontalAlignment="Right" Text="{Binding humanReadableCallDuration}" />
</StackPanel>
</StackPanel>
<StackPanel Orientation="Vertical">
<Button Background="Transparent" BorderThickness="0" BorderBrush="Transparent" Tag="{Binding logID}" Name="btnAddAsContact" Click="btnAddAsContact_Click">
<Image Width="15" Height="15" Source="/BoardiesSMSServer;component/images/add.png" Tag="{Binding logID}" />
</Button>
<Button Background="Transparent" BorderThickness="0" BorderBrush="Transparent" Tag="{Binding logID}" Name="btnDeleteContactFromLog" Click="btnDeleteContactFromLog_Click">
<Image Width="15" Height="15" Source="/BoardiesSMSServer;component/images/delete.png" Margin="0,0,0,5" Tag="{Binding logID}" />
</Button>
</StackPanel>
</StackPanel>
</DockPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
Within my DockPanel within the DataTemplate I have a StackPanel which contains various TextBlocks from the array that is passed into the binding.
In one of the StackPanels you will see you will see a TextBlock that binds to the element of contactNameOrPhoneNumber.
What I want to be able to do is if another value from the binding is null then I add a TextBlock for the contactNameOrPhoneNumber` element and alongside it have another TextBlock which contains another element of number``, if the other binding value is not null then this extra textblock of number is not added.
So in simple terms, what I want to be able to do is within the DataTemplate have a conditional if statement of if binding value == null add textblock to stackpanel else don't add textblock.

You can do that with Style + Triggers something like this:
<TextBlock>
<TextBlock.Style>
<Style TargetType="TextBlock">
<Style.Triggers>
<DataTrigger Binding="{Binding PropertyName}" Value="{x:Null}">
<Setter Property="Visibility" Value="Collapsed"/>
</DataTrigger>
</Style.Triggers>
</Style>
</TextBlock.Style>
</TextBlock>
Also you can create IValueConverter say ObjectToVisibilityConverter which will take input your property and if property is null return Visibility.Collapsed else return Visibility.Visible.
You can then bind property with Visibility value of TextBlock via Converter.
<TextBlock Visibility="{Binding PropertyName,
Converter={StaticResource ObjectToVisibilityConverter}}"/>

StackPanel visiblity "visible" on mouseOver

There are two stackpanels on in the other.
So the first stackpanel is always visible and has a barcode.
I want the second stackpanel x:Name="Verborgen" with Visiblity "Collapsed" to have Visibility "Visible" when mouseOver, the now visible stackpanel needs to have z-Index 9999.
This is the dropbox link to the project:
https://www.dropbox.com/s/8w8horclhfwy4ub/Oefening2.zip
It doesn't work when I add this code to Window.Resources but this is kinda what I want:
<ControlTemplate x:Key="panelControl" TargetType="StackPanel">
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="Verborgen" Property="Visibility" Value="Visible"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
This is the xaml
<Window.Resources>
<model:LocationType x:Key="LocationTypeInstance"/>
<DataTemplate x:Key="WastebinTemplate">
<ContentControl map:MapLayer.Position="{Binding GeoLocation}">
<ContentControl.Content>
<StackPanel Name="form">
<TextBlock Background="{StaticResource Blue}" Text="{Binding Barcode}"/>
<StackPanel Visibility="Collapsed" x:Name="Verborgen" Background="{StaticResource Orange}">
<Button Name="btnRemove" Content="Remove wastebin" Click="btnRemove_Click">
</Button>
<Label>Adres</Label>
<TextBox Name="txbAdres" Text="{Binding Address}"/>
<Label>Location type</Label>
<ComboBox ItemsSource="{Binding Source={StaticResource LocationTypeInstance}, Path=LocationTypes}"
DisplayMemberPath="Description" SelectedItem="{Binding LocationType}" SelectedValuePath="ID" SelectedValue="{Binding LocationType.ID}" />
<Label>Capaciteit</Label>
<Slider Minimum="0" Maximum="100" TickFrequency="10" Value="{Binding Capacity}"></Slider>
</StackPanel>
</StackPanel>
</ContentControl.Content>
</ContentControl>
</DataTemplate>
</Window.Resources>

Try this:
<Window.Resources>
<Style x:Key="Expandable" TargetType="StackPanel">
<Setter Property="Visibility" Value="Collapsed" />
<Style.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource AncestorType=StackPanel}, Path=IsMouseOver}" Value="True" >
<Setter Property="Visibility" Value="Visible" />
</DataTrigger>
</Style.Triggers>
</Style>
<model:LocationType x:Key="LocationTypeInstance"/>
<DataTemplate x:Key="WastebinTemplate">
<ContentControl>
<ContentControl.Content>
<StackPanel Name="form">
<TextBlock Background="{StaticResource Blue}" Text="{Binding Barcode}"/>
<StackPanel x:Name="Verborgen" Background="{StaticResource Orange}" Style="{StaticResource Expandable}">
<Button Name="btnRemove" Content="Remove wastebin" Click="btnRemove_Click">
</Button>
<Label>Adres</Label>
<TextBox Name="txbAdres" Text="{Binding Address}"/>
<Label>Location type</Label>
<ComboBox ItemsSource="{Binding Source={StaticResource LocationTypeInstance}, Path=LocationTypes}"
DisplayMemberPath="Description" SelectedItem="{Binding LocationType}" SelectedValuePath="ID" SelectedValue="{Binding LocationType.ID}" />
<Label>Capaciteit</Label>
<Slider Minimum="0" Maximum="100" TickFrequency="10" Value="{Binding Capacity}"></Slider>
