RequiredValidator (Angular)

This guide demonstrates how to use the RequiredValidator component.

Name Type Default Description
Name string ‘requiredValidator’ + index suffix Unique name of RequiredValidator.
Text string ‘Required’ The text that the validator will display.
Component string null The Name of a input component.
Visible boolean/expression true Is the RequiredValidator visible.


The RequiredValidator is used to verify that an input component (e.g. TextBox, DropDown) has value. It is ideally used inside a TemplateForm component.

  1. Drag and drop a RequiredValidator from the Radzen toolbox.
  2. Set its Component property via the dropdown.
  3. Optionally set the Text of the RequiredValidator.
