How to make my entire tab clicakble in WPF - wpf

Question

I have a TabControl Template and style, but i am having some issues with the clickable are in the tabs.
You will notice that my tab (Border below) has a width and height specified, but unfortunately, the entire border is not clickable, it is only the text inside it, so if i have one letter in the tab, you have to point your mouse exactly on the letter to select the tab.
How can i make it that if you click anywhere on inside the border it selects the tab?
Here is my ControlTemplate:
<Style x:Key="MainTabItem" TargetType="TabItem">
<Setter Property="Foreground" Value="White" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TabItem">
<Border Name="Border" BorderThickness="1,1,1,0" BorderBrush="#EAF1F7" CornerRadius="3,3,0,0" Height="60" Width="70" Margin="-2,0,2,0">
<ContentPresenter x:Name="ContentSite" VerticalAlignment="Center" HorizontalAlignment="Center" ContentSource="Header"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Foreground" Value="Black" />
<Setter TargetName="Border" Property="Background">
<Setter.Value>
<LinearGradientBrush EndPoint="0,1" StartPoint="0,0">
<GradientStop Color="#EDF1FA" Offset="0"/>
<GradientStop Color="#EAF1F7" Offset="1"/>
</LinearGradientBrush>
</Setter.Value>
</Setter>
</Trigger>
<Trigger Property="IsSelected" Value="False">
<Setter TargetName="Border" Property="BorderThickness" Value="0" />
<Setter TargetName="Border" Property="BorderThickness" Value="0" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style x:Key="MainTabControl" TargetType="TabControl">
<Setter Property="BorderThickness" Value="2"></Setter>
<Setter Property="BorderBrush" Value="#CFE2F0"></Setter>
<Setter Property="Background" Value="#EAF1F7"/>
<Setter Property="BorderBrush" Value="#EAF1F7"/>
<Setter Property="Effect">
<Setter.Value>
<DropShadowEffect Direction="150" BlurRadius="20" ShadowDepth="5" Opacity=".3"/>
</Setter.Value>
</Setter>
<Setter Property="Background">
<Setter.Value>
<LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
<GradientStop Offset="0" Color="#EAF1F7" />
<GradientStop Offset=".2" Color="#EAF1F7" />
<GradientStop Offset=".6" Color="#C7D7E4" />
<GradientStop Offset="1" Color="#EAF1F7" />
</LinearGradientBrush>
</Setter.Value>
</Setter>
</Style>

Answer 1

To the border add Background="Transparent".
The reason is that default value for background is null, and pixels with 'null' value are not hit test visible. Transparent pixels are hit test visible (and that's the main reason why 'null' and 'Transparent' exist together).
