Fill (Bind) Datatable from Database in Asp.net using C#, VB.NET

Jul 15, 2015
Introduction

Here I will explain how to fill or bind datatable from database
in asp.net using c#, vb.net with example or get data from database and bind it to datatable in asp.net using c#, vb.net with example.


Before implement this example first design one table productinfo in your database as shown below

Column Name
Data Type
Allow Nulls
productid
Int(IDENTITY=TRUE)
Yes
productname
varchar(50)
Yes
price
varchar(50)
Yes
Once table created in database enter some dummy data to test application now open your aspx page and write the code like as shown below


<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>Bind data to gridview in asp.net using c#, vb.net</title>
<style type="text/css">
.GridviewDiv {font-size: 100%; font-family: 'Lucida Grande', 'Lucida Sans Unicode', Verdana, Arial, Helevetica, sans-serif; color: #303933;}
.headerstyle
{
color:#FFFFFF;border-right-color:#abb079;border-bottom-color:#abb079;background-color: #df5015;padding:0.5em 0.5em 0.5em 0.5em;text-align:center;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div class="GridviewDiv">
<asp:GridView runat="server" ID="gvDetails" AllowPaging="true" PageSize="10" AutoGenerateColumns="false" Width="420px" OnPageIndexChanging="gvDetails_PageIndexChanging">
<HeaderStyle CssClass="headerstyle" />
<Columns>
<asp:BoundField DataField="productid" HeaderText="Product Id" />
<asp:BoundField DataField="productname" HeaderText="Product Name" />
<asp:BoundField DataField="price" HeaderText="Price" />
</Columns>
</asp:GridView>
</div>
</form>
</body>
</html>

After completion of aspx page add following namespaces in codebehind

C# Code


using System;
using System.Web.UI.WebControls;
using System.Data;
using System.Data.SqlClient;

After completion of adding namespaces you need to write the code like as shown below


protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGridview();
}
}
protected void BindGridview()
{
DataSet ds = new DataSet();
using (SqlConnection con = new SqlConnection("Data Source=Suresh;Integrated Security=true;Initial Catalog=MySampleDB"))
{
con.Open();
SqlCommand cmd = new SqlCommand("select * from productinfo", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
con.Close();

gvDetails.DataSource = dt;
gvDetails.DataBind();
}
}
protected void gvDetails_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvDetails.PageIndex = e.NewPageIndex;
BindGridview();
}

VB.NET Code


Imports System.Web.UI.WebControls
Imports System.Data
Imports System.Data.SqlClient
Partial Class VBCode
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
If Not IsPostBack Then
BindGridview()
End If
End Sub
Protected Sub BindGridview()
Dim ds As New DataSet()
Using con As New SqlConnection("Data Source=Suresh;Integrated Security=true;Initial Catalog=MySampleDB")
con.Open()
Dim cmd As New SqlCommand("select * from productinfo", con)
Dim da As New SqlDataAdapter(cmd)
Dim dt As New DataTable()
da.Fill(dt)
con.Close()
gvDetails.DataSource = dt
gvDetails.DataBind()
End Using
End Sub
Protected Sub gvDetails_PageIndexChanging(ByVal sender As Object, ByVal e As GridViewPageEventArgs)
gvDetails.PageIndex = e.NewPageIndex
BindGridview()
End Sub
End Class
