CheckBoxList Bind By Using XmlDataSource in Asp.Net

8/15/2014 - By Pranav Singh 5

This article will show you how you can bind a CheckBoxList using  XML data source and how to retrieve the bind text and value on button click event using c#.net in asp.net.

So for this article first we will create a new asp.net application. After creating a new application first we will create a new XML file and put this XML file into App_Data folder.



Here is the XML file data.

xml version="1.0" encoding="utf-8" ?>
<Country>
  <State Name="Uttar Pradesh" Id="1"></State>
  <State Name="Maharastra" Id="2"></State>
  <State Name="Delhi" Id="3"></State>
  <State Name="Bihar" Id="4"></State>
  <State Name="Asam" Id="5"></State>
</Country>

Now we will add an XML data source and a CheckBoxList list into our page and provide the path if the XML file to the XML datasource.





Now here is the complete code of your .aspx page.

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

<!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>CheckBoxList Bind By Using XmlDataSource in Asp.Net</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:CheckBoxList ID="CheckBoxList1" runat="server" DataSourceID="XmlDataSource1"
            DataTextField="Name" DataValueField="Id">
        </asp:CheckBoxList>
         <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Submit" />
    </div>
    <asp:XmlDataSource ID="XmlDataSource1" runat="server" DataFile="~/App_Data/XML/Country.xml">
    </asp:XmlDataSource>
    <p>
        Text:
        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
    </p>
    <p>
        Id:
        <asp:Label ID="Label2" runat="server" Text="Label"></asp:Label>
    </p>
    </form>
</body>
</html>

Now we will add code to get the selected value of the CheckBoxList on button click.

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 XMLDropdown : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            string selectedItemValue = "";
            string selectedItemText = "";
            for (int i = 0; i < CheckBoxList1.Items.Count; i++)
            {
                if (CheckBoxList1.Items[i].Selected == true)
                {
                    selectedItemValue = selectedItemValue + CheckBoxList1.Items[i].Value + ",";
                    selectedItemText = selectedItemText + CheckBoxList1.Items[i].Text + ",";
                }
                Label1.Text = selectedItemText;
                Label2.Text = selectedItemValue;
            }
        }
    }
}

In above code I have assigned the I have assigned DataSourceID to dropdown and the Text field and the data value field to the dropdown. Now we have done run the page.



Now select some item and click on submit button.
