You should apply the attached property KeyboardNavigation.DirectionalNavigation to the ListBox and set it to KeyboardNavigationMode.Cycle:
<ListBox ItemsSource="{Binding Values}"
KeyboardNavigation.DirectionalNavigation="Cycle" />

Remove lines between rows in WPF grid

Listbox ItemTemplate not rendering correctly

I have a listbox as defined below. Any idea what I need to do to get the border to display? Currently it looks like:
When it should look like:
<ListBox
Grid.Row="1"
ItemsSource="{Binding Path=ProfessionalsView}"
Style="{x:Null}">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>

<TextBlock Grid.Row="3" Text="Mobile Phone"></TextBlock>
<TextBlock Grid.Row="4" Text="Email"></TextBlock>
<TextBlock Grid.Column="1" Grid.Row="0" Margin="9,5,9,2.5" Text="{Binding Path=Surname}"></TextBlock>
<TextBlock Grid.Column="1" Grid.Row="1" Text="{Binding Path=Forenames}"></TextBlock>

<TextBlock Grid.Column="1" Grid.Row="4" Text="{Binding Path=EmailAddress}"></TextBlock>
</Grid>
</HeaderedContentControl>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>

Your border:
<Border BorderThickness="4">
Has no BorderBrush defined. Therefore there's nothing to paint the outlines with. Try
<Border BorderThickness="4" BorderBrush="Black">

You need to set the background Linear Gradiant color for Header. and a Border for you Contents. try below one.
<ListBox
Grid.Row="1"
ItemsSource="{Binding Path=ProfessionalsView}"
Style="{x:Null}">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>

How to add spacing between the listview.items?

I would like to add distance between its items, so I can lead my bind operation on it.
<ListView Margin="0,22,0,0" x:Name="ListViewImages" MouseLeftButtonDown="ListViewImages_MouseLeftButtonDown"
SelectionMode="Extended" ScrollViewer.CanContentScroll="True" ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.HorizontalScrollBarVisibility="Disabled" local:ListBoxExtention.IsRectSelectionEnabled="True">
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Name="WraPanel1" Margin="5" />
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="5" ></RowDefinition>
<RowDefinition Height="150"></RowDefinition>
<RowDefinition Height="15" ></RowDefinition>
<RowDefinition Height="5" ></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="7" x:Name="columnLeft"></ColumnDefinition>
<ColumnDefinition Width="100" x:Name="columnImage"></ColumnDefinition>
<ColumnDefinition Width="7" x:Name="columnRight"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Image Name="Grid_Images" AllowDrop="True" Width="Auto" Height="Auto" Tag="{Binding Id}" Source="{Binding Converter={StaticResource imageConverter}}" Grid.Row="1" Grid.Column="1"
DragEnter="Grid_Images_DragEnter" MouseLeftButtonDown="Grid_Images_MouseLeftButtonDown" MouseLeftButtonUp="Grid_Images_MouseLeftButtonUp"
MouseMove="Grid_Images_MouseMove" Drop="Grid_Images_Drop" KeyUp="Grid_Images_KeyUp" />
<TextBlock Name="Grid_Descrition" AllowDrop="True" TextAlignment="Center" Text="{Binding Id}" Grid.Row="2" Grid.Column="1"/>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>

Hopefully this will save someone else time. I found there are multiple properties that have to be set to 0 in order to completely remove the spacing between ListViewItems in a ListView control. In addition to Margin and Padding I had to set the BorderThickness to 0.
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="Margin" Value="0"/>
<Setter Property="Padding" Value="0"/>
</Style>
</ListView.ItemContainerStyle>

You can just add some Margin to your grid
<Grid Margin="5">
<Grid.RowDefinitions>
<RowDefinition Height="5" ></RowDefinition>
<RowDefinition Height="150"></RowDefinition>
<RowDefinition Height="15" ></RowDefinition>
<RowDefinition Height="5" ></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="7" x:Name="columnLeft"></ColumnDefinition>
<ColumnDefinition Width="100" x:Name="columnImage"></ColumnDefinition>
<ColumnDefinition Width="7" x:Name="columnRight"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Image Name="Grid_Images" AllowDrop="True" Width="Auto" Height="Auto" Tag="{Binding Id}" Source="{Binding Converter={StaticResource imageConverter}}" Grid.Row="1" Grid.Column="1"
DragEnter="Grid_Images_DragEnter" MouseLeftButtonDown="Grid_Images_MouseLeftButtonDown" MouseLeftButtonUp="Grid_Images_MouseLeftButtonUp"
MouseMove="Grid_Images_MouseMove" Drop="Grid_Images_Drop" KeyUp="Grid_Images_KeyUp" />
<TextBlock Name="Grid_Descrition" AllowDrop="True" TextAlignment="Center" Text="{Binding Id}" Grid.Row="2" Grid.Column="1"/>
</Grid>

Add a ListView.ItemContainerStyle and create a Setter that applies a Margin of whatever size you prefer.

Style each datagrid column header

I want to add another row to the HeaderRow and for each column insert specific control.
This is my code where add this row, but I can only set same control (in this case textbox) for every column, but I want to set specific control for specific column.
(like it's done in ASP.NET repeater)
<Style x:Key="DataGridColumnHeaderStyle1" TargetType="{x:Type DataGridColumnHeader}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridColumnHeader}">
<Grid x:Name="grid" VerticalAlignment="Center" HorizontalAlignment="Stretch" Background="{TemplateBinding Background}">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBlock Name="ColumnHeader" Grid.Row="0" Text="{TemplateBinding Content}" HorizontalAlignment="Center" VerticalAlignment="Center" Height="18" />
<Grid Grid.Row="1">
<TextBox Text="" HorizontalAlignment="Stretch" BorderThickness="0,1,1,1" />
</Grid>
</Grid>
</Style>

You can Make use of the HeaderTemplate to specify different datatemplates for each Column
Sample
<Window.Resources>
<DataTemplate x:Key="Template1">
<Grid x:Name="grid" VerticalAlignment="Center" HorizontalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBlock Name="ColumnHeader" Text="Student Id" Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Center" Height="18" />
<Grid Grid.Row="1">
<TextBox Text="" HorizontalAlignment="Stretch" BorderThickness="0,1,1,1" />
</Grid>
</Grid>
</DataTemplate>
<DataTemplate x:Key="Template2">
<Grid x:Name="grid" VerticalAlignment="Center" HorizontalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBlock Name="ColumnHeader" Text="Student Name" Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Center" Height="18" />
<Grid Grid.Row="1">
<TextBox Text="" HorizontalAlignment="Stretch" BorderThickness="0,1,1,1" />
</Grid>
</Grid>
</DataTemplate>
</Window.Resources>
<Grid>
<DataGrid Name="dataGrid" >
<DataGrid.Columns>
<DataGridTextColumn HeaderTemplate="{StaticResource Template1}" Width="90*" MinWidth="120" Binding="{Binding StudentId}"/>
<DataGridTextColumn HeaderTemplate="{StaticResource Template2}" Width="90*" MinWidth="120" Binding="{Binding Name}"/>
<DataGridTextColumn Header="Score" Width="100*" MinWidth="150" Binding="{Binding Score}"/>
</DataGrid.Columns>
</DataGrid>
</Grid>

I approached this a little bit different, I styled DataGridColumnHeadersPresenter, it allows me to syle the column headers row (instead of column header).
There I add my new row and all the controls I need, I alsoe set the width of every cell to match the width of it's header .
<Style x:Key="DataGridColumnHeadersPresenterStyle1" TargetType="{x:Type DataGridColumnHeadersPresenter}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type DataGridColumnHeadersPresenter}">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<DataGridColumnHeader x:Name="PART_FillerColumnHeader" IsHitTestVisible="False"/>
<ItemsPresenter/>
<Grid Grid.Row="1" VerticalAlignment="Top" HorizontalAlignment="Left" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="{Binding ActualWidth, ElementName=Col1}"/>
<ColumnDefinition Width="{Binding ActualWidth, ElementName=Col2}"/>
<ColumnDefinition Width="{Binding ActualWidth, ElementName=Col3}"/>
</Grid.ColumnDefinitions>
<TextBox Grid.Column="0" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Bottom" Width="Auto" Height="25" BorderThickness="1,2,0,2"/>
my other controls go here
</Grid>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
