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>
<bs:FormGroup LabelText="Password">
<bs:TextBox ID="password" Text="{value: Password}" Type="Password"/>
<bs:HelpText AssociatedControlID="password">
A simple help text for Input Password
</bs:HelpText>
</bs:FormGroup>
</bs:Form>using DotVVM.Framework.ViewModel;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace DotvvmWeb.Views.Docs.Controls.bootstrap.HelpText.sample1
{
public class ViewModel : DotvvmViewModelBase
{
public string Password { get; set; }
