Gets/sets the minimum length (inclusive) allowed for the constrained value. This constraint applies to values of type 'string'. The default value is 0, which means there is no minimum length constraint.
The following code snippet sets the ValueConstraint on a text editor. It sets the MinLength and MaxLength properties of the value constraint. This will ensure that the length of what user enters into the editor is between 2 and 4 characters. If the value entered does not satisfy all the constraints of the value constraint object then the editor will display an error message when the user attempts to leave the editor. The action taken by the editor can be controlled using the InvalidValueBehavior property of the editor.
<!--This editor will make sure that the text entered is between 2 and 4 characters long-->
