MaxLength Property

Gets/sets the maximum length (inclusive) allowed for the constrained value. This constraint applies to values of type 'string'. The default value is 0, which means that there is no limit.

Syntax

Visual Basic

'Declaration
 
Public Property MaxLength As Integer

C#

public int MaxLength {get; set;}

Remarks

MaxLength constraint will ensure that the data value being validated has a length that's less than or equal the value of this property.

Note: If the data value being validated is not a string object then it will be converted to string before performing this validation.

Example

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.

XAML

<!--This editor will make sure that the text entered is between 2 and 4 characters long-->
<igEditors:XamTextEditor x:Name="textEditor3" InvalidValueBehavior="DisplayErrorMessage" >
    <igEditors:XamTextEditor.ValueConstraint>
        <igEditors:ValueConstraint MinLength="2" MaxLength="4" />
    </igEditors:XamTextEditor.ValueConstraint>
</igEditors:XamTextEditor>
