Binding from a Setter in Codebehind to a brushdefinied in resources

Hey,

i temporaly inside a Style for a control in codebehind. There, i applied a Trigger. This Trigger should bind to a brush, which is definied inside a ResourceDicionary. So, the StaticResource Keyword is the right one. But how is the correct Notation?

i tried:

newSetter(DataGridRow.BorderBrushProperty,newBinding() { Path = newPropertyPath("StaticResource TabItemRowSelectedBorderBrush") }));

but this doesn't work.
