ValueConstraint Property

Gets or sets the constraints for editor input. Default value is null.
Syntax
'Declaration
 
Public Property ValueConstraint As ValueConstraint
public ValueConstraint ValueConstraint {get; set;}
Remarks

Note that the default value of this property is null. You must set the property to an instance of ValueConstraint object.

ValueConstraint is used to limit what the user can input into the editor. More accurately, the editor will consider user input invalid if it doesn't satisfy one or more criteria specified by the ValueConstraint. The IsValueValid property can be used to find out if editor considers current value valid.

When an invalid value is entered into the editor, there are behavioral implications based on various settings. For example, by default the editor doesn't exit edit mode when the current input is invalid. The action taken by the editor can be controlled using the InvalidValueBehavior property.
