In this article I will explain with an example, how to bind / fill/ populate DataTable from Database in ASP.Net using C# and VB.Net.
Database
I have made use of the following table Customers with the schema as follows.
![Bind / Fill / Populate DataTable from Database in ASP.Net using C# and VB.Net]()
I have already inserted few records in the table.

Namespaces
You will need to import the following namespaces.
C#
using System.Data;
using System.Configuration;
using System.Data.SqlClient;
VB.Net
Imports System.Data
Imports System.Configuration
Imports System.Data.SqlClient
Bind / Fill / Populate DataTable from Database
Inside the Page Load event of the page, the DataTable is populated with the records of the Customers Table.
C#
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
using (SqlConnection con = new SqlConnection(constr))
{
using (SqlCommand cmd = new SqlCommand("SELECT CustomerId, Name, Country FROM Customers"))
{
cmd.Connection = con;
using (SqlDataAdapter sda = new SqlDataAdapter(cmd))
{
DataTable dt = new DataTable();
sda.Fill(dt);
}
}
}
}
}
VB.Net
Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
If Not Me.IsPostBack Then
Dim constr As String = ConfigurationManager.ConnectionStrings("constr").ConnectionString
Using con As New SqlConnection(constr)
Using cmd As New SqlCommand("SELECT CustomerId, Name, Country FROM Customers")
cmd.Connection = con
Using sda As New SqlDataAdapter(cmd)
Dim dt As New DataTable()
sda.Fill(dt)
End Using
End Using
End Using
End If
End Sub
Screenshot
