wpf - Expander button on the right side: how to do it?

Question

i want to position the Expander button on the right side of the label. How to do this?

Answer 1

You can also set the FlowDirection to RightToLeft, but that may cause other problems. For example it also changes the flow direction for the content of the expander so you may need to set it back.

<Expander FlowDirection="RightToLeft">
     <StackPanel FlowDirection="LeftToRight">
     </StackPanel>
</Expander>
