EmailValidator component

This article demonstrates how to use RadzenEmailValidator.

Basic usage

RadzenEmailValidator checks if the user input is a valid email address.

To use it perform these steps:

1. Add an input component and set its Name. Data-bind its value to a model property via @bind-Value=@model.Email.
2. Add RadzenEmailValidator and set its Component property to the Name of the input component.

Important

RadzenEmailValidator works only inside RadzenTemplateForm.

Here is a typical user registration form which checks if the user entered the same password.

<RadzenTemplateForm TItem="Registration" Data=@model>
    <p>
      <RadzenLabel Text="Email" />
      <RadzenTextBox Name="Email" @bind-Value=@model.Email />
      <RadzenEmailValidator Component="Email" Text="Enter email" />
    </p>
    <RadzenButton ButtonType="ButtonType.Submit" Text="Submit"></RadzenButton>
</RadzenTemplateForm>
@code {
    class Registration
    {
        public string Email { get; set; }
    }

    Registration model = new Registration();
}

Conditional validation

To make the validator conditional you can set its Visible property. When set to false the validator will not run.

Appearance

By default RadzenEmailValidator appears next to the component it validates.

To make it appear below set its Style to "display:block".

<RadzenTextBox Name="Email" @bind-Value=@model.Email />
<RadzenEmailValidator Component="Email" Text="Enter email" Style="display:block" />

To make it appear as a styled popup set its Popup property to true and set its CSS position to absolute. The validated component should have display: block so the validation message appears right below it.

<RadzenTextBox Name="Email" @bind-Value=@model.Email Style="display:block" />
<RadzenEmailValidator Component="Email" Text="Enter email" Style="position:absolute" Popup="true" />
