In this article I will explain how to bind data to datatable and display it on our aspx page using JQuery or JSON in asp.net.
Description:
In previous article I explained how to bind data to gridview with JQuery. Now I am using same concept to explain how to bind data to datatable using JQuery/JSON and display it on aspx page in asp.net.
To implement this concept first we need to design table in database give name as UserInformation to save user details in database.

Column Name
|
Data Type
|
Allow Nulls
|
UserId
|
int(set
identity property=true)
|
No
|
UserName
|
varchar(50)
|
Yes
|
Location
|
nvarchar(max)
|
Yes
|
After completion
table design enter some of user details in database to work for our sample.
Now create new
website and write the following code in your
aspx page
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"
runat="server">
<title>Asp.net Bind Data to Datatable using JQuery or JSON</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
$.ajax({
type: "POST",
contentType: "application/json;
charset=utf-8",
url: "Default.aspx/BindDatatable",
data: "{}",
dataType: "json",
success: function(data)
{
for (var i = 0; i <
data.d.length; i++) {
$("#tbDetails").append("<tr><td>" +
data.d[i].UserId + "</td><td>"
+ data.d[i].UserName + "</td><td>"
+ data.d[i].Location + "</td></tr>");
}
},
error: function(result)
{
alert("Error");
}
});
});
</script>
<style type="text/css">
table,th,td
{
border:1px solid black;
border-collapse:collapse;
}
</style>
</head>
<body>
<form id="form1"
runat="server">
<table id="tbDetails"
cellpadding="0"
cellspacing="0">
<thead style="background-color:#DC5807; color:White; font-weight:bold">
<tr style="border:solid 1px #000000">
<td>UserId</td>
<td>UserName</td>
<td>Location</td>
</tr>
</thead>
<tbody>
</tbody>
</table>
</form>
</body>
</html>

If
you observe above code in header section I added script file link by using that
file we have a chance to interact with JQuery and if you want to know the
script function declared in header section check these posts JQuery UI AutoComplete textbox with
database and call asp.net pagemethods in JQuery. Here I explained that
function clearly.
Now
open code behind file and add the following namespaces
using System;
using System.Data;
using System.Data.SqlClient;
using System.Web.Services;
using System.Collections.Generic;
|
After
that write the following code in code behind
C#.NET Code
protected void
Page_Load(object sender, EventArgs e)
{
}
[WebMethod]
public static UserDetails[] BindDatatable()
{
DataTable dt = new DataTable();
List<UserDetails>
details = new List<UserDetails>();
using (SqlConnection
con = new SqlConnection("Data Source=SureshDasari;Initial
Catalog=MySampleDB;Integrated Security=true"))
{
using (SqlCommand
cmd = new SqlCommand("select TOP 10 UserId,UserName,Location from
UserInformation", con))
{
con.Open();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
foreach (DataRow
dtrow in dt.Rows)
{
UserDetails user = new UserDetails();
user.UserId = dtrow["UserId"].ToString();
user.UserName = dtrow["UserName"].ToString();
user.Location = dtrow["Location"].ToString();
details.Add(user);
}
}
}
return details.ToArray();
}
public class UserDetails
{
public string
UserId { get; set;
}
public string
UserName { get; set;
}
public string
Location { get; set;
}
}
|
VB.NET Code:
Imports System.Collections.Generic
Imports System.Data
Imports System.Data.SqlClient
Imports System.Web.Services
Partial Class
VBSample
Inherits System.Web.UI.Page
Protected Sub
Page_Load(ByVal sender As Object, ByVal e As
EventArgs) Handles Me.Load
End Sub
<WebMethod()> _
Public Shared Function BindDatatable() As
UserDetails()
Dim dt As New DataTable()
Dim details As New List(Of
UserDetails)()
Using con As New SqlConnection("Data
Source=SureshDasari;Initial Catalog=MySampleDB;Integrated Security=true")
Using cmd As New SqlCommand("select
TOP 10 UserId,UserName,Location from UserInformation", con)
con.Open()
Dim da As New SqlDataAdapter(cmd)
da.Fill(dt)
For Each dtrow As DataRow In
dt.Rows
Dim user As New UserDetails()
user.UserId = dtrow("UserId").ToString()
user.UserName = dtrow("UserName").ToString()
user.Location = dtrow("Location").ToString()
details.Add(user)
Next
End Using
End Using
Return details.ToArray()
End Function
Public Class
UserDetails
Public Property
UserId() As String
Get
Return m_UserId
End Get
Set(ByVal value As String)
m_UserId = Value
End Set
End Property
Private m_UserId As String
Public Property
UserName() As String
Get
Return m_UserName
End Get
Set(ByVal value As String)
m_UserName = Value
End Set
End Property
Private m_UserName As
String
Public Property
Location() As String
Get
Return m_Location
End Get
Set(ByVal value As String)
m_Location = Value
End Set
End Property
Private m_Location As
String
End Class
End Class
