WPF XAML resize <infrastructure:Plugin> width to the content in it

I have an interface with some tabs in it on the right side of the screen. I need each tab`s width to be resized by width of the context in it.
All the other tabs do it apart from this one...
Any suggestions, please?
Description
The scales tab in the stackup editor doesn’t resize when selected.
Select the scales tab on the right side of the stackup editor
Right hand tab doesn’t resize
Expected Behaviour
Tab resizes to fit content, as with all other tabs in the stackup
editor

WPF Grid Rows and ResizeGrip do not anchor correctly

once again after hours of struggle with WPF I need your awesome help.
I have read many different StackOverflows, nonetheless, I cannot seem to get my current situation working and I don't understand why. I have chosen to use a Grid in contrast to a DockPanel and I would like to keep it that way as well. According to what I have read the row definitions are ok, the second row of the template grid should automatically stretch. Unfortunately it does not, as it seems that the last row of the grid does not move away.
This is how my window looks at the moment:
As you can see is the blue row not at the bottom of the window. In fact, the window should not be that long in the first place.
This is the code snippet of my Generic.xaml file that is relevant to the problem.
The way it works is, that I have a Skin with a custom control group:
<!-- Window START-->

I cannot explain myself why the "blue bar" is not attached to the bottom. Despite the fact, that the window is so big.

I think you want to change this:
<Grid x:Name="WindowRoot" Margin="0" VerticalAlignment="Top" Background="Blue" MouseDown="Window_MouseDown">
to this:
<Grid x:Name="WindowRoot" Margin="0" VerticalAlignment="Stretch" Background="Blue" MouseDown="Window_MouseDown">

Can anyone tell me where is the problem.Any help would be highly appreciable.

It seems that one of the StaticResources used does not exist:
Either:
AddHwType (Button Style)
AppButtons (Button Style)
BooleanToVisibilityConverter (Converter)
You might miss a merged dictionary somewhere or forgot to add a resource before using it. Review the XAML Resources page on MSDN for more info.

Solved:I was using wrong Static Resource i was writingStyle="{StaticResource AddHwType }" and it should be Style="{StaticResource AppButtons}" :)
