How to show ToolTips on disabled controls

When you disable a control with IsEnabled=False the tooltip does not show anymore. If you want to have the tooltip appear anyway you have to set the attaached property ToolTipService.ShowOnDisabled to True.

 
<Button IsEnabled="False" 
        ToolTip="Saves the current document"
        ToolTipService.ShowOnDisabled="True"
        Content="Save">
</Button>
 
 

How to change the show duration of a ToolTip

<Button ToolTip="Saves the current document"
        ToolTipService.ShowDuration="20"
        Content="Save">
</Button>
