Validating radiobuttonlist

The following example shows two panels that contain three radio buttons each.

One radio button from each panel are grouped together.

I tried many different ways but no luck, here is my code. Page Protected Sub Page_Load(By Val sender As Object, By Val e As System. Load End Sub 'Protected Sub Calendar1_Selection Changed(sender As Object, e As Event Args) ' Text Box1. Visible = True 'End Sub 'Protected Sub Calendar2_Selection Changed(sender As Object, e As Event Args) ' Text Box2.

This behavior is the same for the native ASP button components as well and conceptually cannot be validated using a Required Field Validator.

The only button-related components that, by design, should support the Required Field Validator integration are Check Box List and Radio Button List controls.

The setup and validation of radio buttons appears to be the form field that gives many webmasters the most difficulty in setting up.

In actual fact the setup of these fields is the most simple of all form fields to validate as radio buttons set one value that only needs to be tested when the form is submitted.

I am working on a school project which I have to validate the input from the user.

Everytime the page load, it give the server error message.

Simple Form Controller; import com.mkyong.customer.model. Customer; public class Radio Button Controller extends Simple Form Controller package com.mkyong.customer.validator; import org.springframework.validation. Validation Utils; import org.springframework.validation.

Radio Buttons, Checkboxes etc cannot be validated using a traditional Required Field Validator.

The remaining two radio buttons on each panel are not grouped explicitly, which means they are grouped together since they share the same parent control.

Hello, Rad Button and any other components from the button family (like Rad Push Button, Rad Check Box Button and so on) does not support the Required Field Validator.

If you try to assign Control To Validate property of Required Field Validator to a Radio Button ID then it will welcome you with an error message.
