Question

This value:

{Binding Source={x:Static shell:SystemParameters2.Current}, Path=WindowNonClientFrameThickness}

Is usually something like 8,24,8,8 depending on your OS settings. Now, I need to retrieve the “top” value (i.e. 24 in this example) and negate that into -24 and use it for a margin:

<TabControl Margin="0,-24,0,0" />

But how do I retrieve that value, negate it, and place it for the tab’s top margin value?

If it matters, I’m using the https://nuget.org/packages/Microsoft.Windows.Shell

Answer 1

I would probably just create a value converter which contructs the Margin. (Thickness is a struct, so you cannot just bind the Top property only)
