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.

Some of my previous articles are as follows: DropDownList Bind By Using XmlDataSource in Asp.Net, Disable jQuery UI DatePicker Calendar On Button Click In Asp.Net,Bind DropDownList Using Entity Framework in ASP.Net MVC Using C#, C# Conversion of DateTime to 24 Hours Time in Asp.Net | Display 24 Hour Time In DropDownList In Asp.net, Load Partial View By Selecting Value in Dropdown Using C# in Asp.net MVC, jQuery DatePicker Calendar With Dropdown Month and Year in Asp.Net,How to Bind xml to DataGridView Using C#.Net In Windows Application, Read XML File into DataSet and Populate in ComboBox Using C# in Windows Application, Gridview Export to XML in Asp.Net Using C#.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>

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">

<title>CheckBoxList Bind By Using XmlDataSource in Asp.Net</title>

</head>

<body>

<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.
