using
System.Data;
using
System.Data.SqlClient;

SqlConnection
con = new SqlConnection(ConfigurationManager.ConnectionStrings["connection"].ToString());
protected void Page_Load(object
sender, EventArgs e)
{
if
(!IsPostBack)
{
BindDatalist();
}
}
public void BindDatalist()
{
try
{
SqlDataAdapter
adp = new SqlDataAdapter("Select * from Tb_Product", con);
DataTable
dt = new DataTable();
adp.Fill(dt);
if
(dt.Rows.Count > 0)
{
dlproducts.DataSource = dt;
dlproducts.DataBind();
}
}
catch (Exception ex)
{
}
}
VB:-

con As New SqlConnection(ConfigurationManager.ConnectionStrings("connection").ToString())
Protected Sub Page_Load(sender As
Object, e As
System.EventArgs) Handles
Me.Load
If Not IsPostBack Then
BindDatalist()
End If
End Sub
Public Sub BindDatalist()
Try
Dim
adp As New SqlDataAdapter("Select
* from Tb_Product", con)
Dim
dt As New DataTable()
adp.Fill(dt)
