<object VerticalOffset="qualifiedDouble"/>

XAML Values

double

Double

The string representation of a Double value that is equal to or greater than 0.0 but smaller than Double.PositiveInfinity. This is interpreted as a device-independent unit (1/96th inch) measurement. Strings do not have to explicitly include decimal points.

qualifiedDouble

A Double value that is followed by one of these unit declaration strings: px, in, cm, pt.

px (default) is device-independent units (1/96th inch per unit)

in is inches; 1in==96px

cm is centimeters; 1cm==(96/2.54) px

pt is points; 1pt==(96/72) px

Property Value

Type: System.Double
A value that specifies a vertical distance. The default value is zero (0).

Identifier field

Metadata properties set to true

None

This property is an attached property. For information about how to get or set the value of this property in code, see the GetVerticalOffset and SetVerticalOffset methods. VerticalOffset behaves similarly to the Popup.VerticalOffset property. For more information, see Popup Placement Behavior.

This example shows how to specify the position of a tooltip on the screen.

You can position a tooltip by using a set of five properties that are defined in both the ToolTip and ToolTipService classes. The following table shows these two sets of five properties and provides links to their reference documentation according to class.

Corresponding tooltip properties according to class

If you define the contents of a tooltip by using a ToolTip object, you can use the properties of either class; however, the ToolTipService properties take precedence. Use the ToolTipService properties for tooltips that are not defined as ToolTip objects.

The following illustrations show how to position a tooltip by using these properties. Although, the Extensible Application Markup Language (XAML) examples in these illustrations show how to set the properties that are defined by the ToolTip class, the corresponding properties of the ToolTipService class follow the same layout rules. For more information about the possible values for the Placement property, see Popup Placement Behavior.

The following example shows how to use the ToolTip properties to specify the position of a tooltip whose content is a ToolTip object.
