while Inherit style in WPF it affect parent style

In WPF i have a style for the control like below,

 <Style TargetType="local:CustomControl">
    <Setter Property="Background" Value="Transparent" />
    <Setter Property="BorderBrush" Value="Gray" />
    <Setter Property="BorderThickness" Value="0,0,0,1" />
    <Setter Property="Padding" Value="3,0,3,0" />
    <Setter Property="IsTabStop" Value="False" />
    <Setter Property="VerticalContentAlignment" Value="Center" />
 </Style>

Now i need to override customcontrol border for some other place like below,

<Style TargetType="local:CustomControl" BasedOn="{StaticResource  {x:Type local:CustomControl}}">
    <Setter Property="BorderThickness" Value="1" />
</Style>

My problem is when i am using above code it override the 1st written code. is my code is correct.

Note: the base style is only written with target type. i need to override that control border in some other place without affect base code.

is it possible ? please help me to resolve this problem.

thanks in advance.

Best How To :

If you declare a Style without an x:Key, it will override the default style for that control.

<Style TargetType="local:CustomControl">

So the code above will effect all CustomControl elements throughout the entire application (or within the scope).

If you do not want to override the base style, you can give your Style an x:Key, like so:

<Style TargetType="local:CustomControl" x:Key="MyAwesomeStyle">

When you create your control, you will then have to reference the Style. Here's an example:

<local:CustomControl Style="{DynamicResource MyAwesomeStyle}" ... />
