Sample 1: HelpText Usage

Use the AssociatedControlID property to specify the ID of the control which the help text is applied to.

This will ensure that assistive technologies, such as screen readers, will announce this help text when the user focuses or enters the control.

<bs:Form Type="Vertical">
  
    <bs:FormGroup LabelText="Email">
    <bs:FormStaticValue>[email protected]</bs:FormStaticValue>
  </bs:FormGroup>
  
  <bs:FormGroup LabelText="Input Password">
    <dot:TextBox ID="inputHelpBlock" Text="{value: Password}" Type="Password"/>
    <bs:HelpText ID="help" AssociatedControlID="inputHelpBlock">
      A simple help text for Input Password
    </bs:HelpText>
  </bs:FormGroup>
