Database
For this blog i have created a Database and Simple Table with the two column “HobbiesId “, “HobbiesName “.
[php]
create database CheckBoxList_Demo
use CheckBoxList_Demo
create table tblHobbies(
HobbiesId int primary key identity(1,1),
HobbiesName varchar(40)
)
[/php]
Insert record into Table “tblHobbies”.
[php]
insert into tblHobbies(HobbiesName)values(‘Cricket’),(‘Dancing’),(‘Reading’),(‘Swimming’),(‘Singing’),(‘Comedy’)
[/php]
Create Stored procedure for Get Record from Database.
[php]
create proc sp_tblHobbies_Select
as
begin
select * from tblHobbies
end
[/php]
Now Open Visual Studion and create the project as:
“Start” –> “All Programs”- “Microsoft Visual Studio 2012”.
“File” – “New Project” – “C#” – “Empty Project” (to avoid adding a master page).
Give the Project name such as “CheckBoxList_Demo” or another as you wish and specify the location.
Then right-click on Solution Explorer – “Add New Item” – “Default.aspx” page.
Open Default.aspx page and write this code.
In “Default.aspx” page drag and drop one of an ASP.Net CheckBoxList control .Open “Default.aspx” page put this code.
Default.aspx/HTML
[php]
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="CheckBoxList_Demo.Default" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<table>
<tr>
<td>Select Hobbies:</td>
<td>
<asp:CheckBoxList ID="cblhobbies" runat="server" RepeatColumns="3"></asp:CheckBoxList></td>
</tr>
</table>
</div>
</form>
</body>
</html>
[/php]
Open web.config file and Establish a connection with database
Key Point:
- In initial catalog write Database Name
- In data source you can simply write (.) /your server name/(local)
- Integrated security for Authentication
[php]
<connectionStrings>
<add name="DBCS" connectionString="data source=.;initial catalog=CheckBoxList_Demo;integrated security=true"/>
</connectionStrings>
[/php]
Open “Default.aspx.cs” page to write code for How to Bind CheckBoxList from Database in ASP.Net C#.
Default.aspx.cs
[php]
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
//Need to import the following Namespaces
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
namespace CheckBoxList_Demo
{
public partial class Default : System.Web.UI.Page
{
//Establish Connection
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString);
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
//The BindHobbies() method is called up in the page load event.
BindHobbies();
}
}
//Create one method "BindHobbies" for populate hobbies from Database
public void BindHobbies()
{
con.Open();
SqlCommand cmd = new SqlCommand("sp_tblHobbies_Select", con);
cmd.CommandType = CommandType.StoredProcedure;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
con.Close();
if (ds.Tables[0].Rows.Count > 0)
{
cblhobbies.DataValueField = "HobbiesId"; //"HobbiesId" is the tblHobbies Column Name
cblhobbies.DataTextField = "HobbiesName";//"HobbiesName" is the tblHobbies Column Name
cblhobbies.DataSource = ds;
cblhobbies.DataBind();
}
}
}
}
[/php]
