Expander.Header ToolTip active even with Expander.IsEnabled=false

Question

If the Expander.IsEnabled=false then the tooltip on the header is not active.
Is there a way to have a ToolTip even if Expander.IsEnabled=false?

 <Expander.Header>
      <TextBlock Text="Export" ToolTip="ToolTip - I don't show up if Expander.IsEnabled=false" 
                 Style="{StaticResource TabItemHeaderSemiBold11}"/>
 </Expander.Header>

Answer 1

Try setting ToolTipService.ShowOnDisabled="True":

<Expander IsEnabled="False">
    <Expander.Header>
        <TextBlock Text="Export" ToolTip="ToolTip - I don't show up if Expander.IsEnabled=false"
                ToolTipService.ShowOnDisabled="True"/>
    </Expander.Header>
</Expander>
