6/11/2014 - By Pranav Singh 0

Radiobuttonlist control is an asp.net control. We use this control to show list of item in the form of list. In this article I will show you how you can validate a Radiobuttonlist control in asp.net Using RequiredFieldValidator Validation Control.

In previous article I have shown you RadioButtonList Validation Using jQuery in Asp.Net.



Now or this article first we will create an asp.net application and add a rediobuttonlist control. After adding the control your code will look as shown below:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="RadioButtonValidation.aspx.cs" Inherits="ProjectDemo_Asp.et.RadioButtonValidation" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Asp.Net-Validating Radio Button List using Required Filed Validator
</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
   
       <h3> Validate RadioButtonList </h3>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
            ControlToValidate="RadioButtonList1"
            ErrorMessage="Please select attleast one country" BorderStyle="None"
            ForeColor="Red"></asp:RequiredFieldValidator>
        <asp:RadioButtonList ID="RadioButtonList1" runat="server" RepeatColumns="3"
            BorderColor="#FF0066" BorderStyle="Dotted">
            <asp:ListItem>India</asp:ListItem>
            <asp:ListItem>Pakistan</asp:ListItem>
            <asp:ListItem>America</asp:ListItem>
            <asp:ListItem>Bangla Deah</asp:ListItem>
            <asp:ListItem>Afghanistan</asp:ListItem>
            <asp:ListItem>Afghanistan</asp:ListItem>
        </asp:RadioButtonList>
        <br />
        <asp:Button ID="Button1" runat="server" Text="Click"
            OnClientClick="javascript:return ValidateRedioButtonList();" onclick="Button1_Click"/>
   
    </div>
    </form>
</body>
</html>

For getting the selected value in our code end we have used below mention code

C#.Net
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace ProjectDemo_Asp.et
{
    public partial class RadioButtonValidation : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            string countryname = RadioButtonList1.SelectedValue.ToString();
            Page.ClientScript.RegisterStartupScript(this.GetType(), "Your Selected Country", "alert('You have selected : " + countryname + ".');", true);
        }
    }
}

VB.Net
Imports System
Imports System.Collections.Generic
Imports System.Linq
Imports System.Web
Imports System.Web.UI
Imports System.Web.UI.WebControls

Namespace ProjectDemo_Asp.et
    Partial Public Class RadioButtonValidation
        Inherits System.Web.UI.Page
        Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

        End Sub

        Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)
            Dim countryname As String = RadioButtonList1.SelectedValue.ToString()
            Page.ClientScript.RegisterStartupScript(Me.[GetType](), "Your Selected Country", "alert('You have selected : " + countryname + ".');", True)
        End Sub
    End Class
End Namespace

Now we have done. View the page in browser.
