displays these records to the user in the DataGridView control. The following snippet shows the code for
this example (excluding the form and control definition code):
using System;
using System.Configuration;
using System.Data;
using System.Data.Common;
using System.Data.SqlClient;
using System.Windows.Forms;
namespace DisplayTabularData
{
partial class Form1: Form
{
public Form1()
{
InitializeComponent();
}
private void getData_Click(object sender, EventArgs e)
{
string customers = "SELECT * FROM Customers";
using (SqlConnection con =
new SqlConnection (ConfigurationManager.
ConnectionStrings["northwind"].ConnectionString))
{
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter(customers, con);
da.Fill(ds, "Customers");
dataGridView.AutoGenerateColumns = true;
dataGridView.DataSource = ds;
dataGridView.DataMember = "Customers";
}
}
}
