Property Value

Type	Default	Description
DefaultBoolean	Default	A DefaultBoolean enumeration value that specifies whether or not this ValidationHint object should draw a border around its target UI element.

Available values:

Name	Description
True	true. DefaultBoolean.True has a constant value of 0, while the standard true value corresponds to a value of 1. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
False	false. DefaultBoolean.False has a constant value of 1, while the standard false value corresponds to a value of 0. In Visual Basic, do not use implicit conversion of Boolean values to DefaultBoolean, and vice versa, as the conversion may produce incorrect results.
Default	The default behavior determined by the control’s logic.

Remarks

A border drawn around a target UI element can accompany a hint with text and an image (see the figure below). To colorize these elements, use the appearance settings accessed through the ValidationHint.Appearances group.

The ShowBorder and ValidationHintBaseDefaultProperties.ShowHint properties are accessed through the ValidationHint.Properties group, which provides three sets of properties, one for each available control navigation state - valid, invalid and indeterminate. Thus, you can customize the ValidationHint object’s behavior for each validation state separately.

If the ShowBorder property equals DefaultBoolean.Default, this ValidationHint will act based on the global behavior (the ValidationHintBaseProperties.ShowBorder property). Otherwise, the ShowBorder setting will be prioritized.
