Can I delay the display of a ToolTip ?

You can set a ‘ToolTipService’ property that causes a brief delay before a ToolTip displays. You set the properties of the ‘ToolTipService’ class by attaching them directly to the element that exposes the tooltip.

[XAML]
 
<TextBox HorizontalAlignment='Left' ToolTipService.InitialShowDelay='1500'
ToolTip='Useful information goes here.'>
     ToolTip with delay
   </TextBox>
