Tool Tip

The tool tip is a popup that shows its content when the user hovers over the 'host' control to which it is attached.

Useful Properties

You will probably use these properties most often:

Property	Description
ToolTip.Tip	Attached property for the tooltip contents.
ToolTip.Placement	Defines the placement for the tooltip relative to the host or the pointer. Choose from top, bottom, left, right, anchor and gravity, pointer. The default value is pointer which places the tip content at the position where the pointer stops moving.
ToolTip.HorizontalOffset	The tooltip horizontal offset from the placement (default 0).
ToolTip.VerticalOffset	The tooltip vertical offset from the placement (default 20).
ToolTip.ShowDelay	The amount of time the pointer has to be still before the tooltip appears. In microseconds (default 400).

Examples

This is a simple text-based tooltip, using default values for the placement and delay properties; this rectangle is placed in a window with larger dimensions:

<Rectangle Fill="Aqua" Height="200" Width="400"
            ToolTip.Tip="This is a rectangle" />

To provide a richer presentation for a tooltip, use a <ToolTip.Tip> element. For example:

<Rectangle Fill="Aqua" Height="200" Width="400"
    ToolTip.Placement="Bottom">
    <ToolTip.Tip>
      <StackPanel>
        <TextBlock FontSize="16">Rectangle</TextBlock>
        <TextBlock>Some explanation here.</TextBlock>
      </StackPanel>
    </ToolTip.Tip>
</Rectangle>
