MultiLineTextBoxValidator component released

Fluent.MultiLineTextBoxValidator is a validator control which will restrict the length of MultiLine TextBox controls. The MaxLength property of the .NET TextBox control does not have any effect if the TextMode property is set to MultiLine. This is because MultiLine TextBox controls are rendered in HTML as TEXTAREA tags, which cannot have a restricted length. This control adds Javascript support to achieve the length restriction. In addition it can provide feedback of the number of characters remaining before the MaxLength cutoff will be reached. Demo and download now!
