I have been able to use data reader to populate gwCategory (a grid view control) using a data reader variable. But I need some help to do the same using a data adapter.

Question: How can I make the attached code work?

This is in vs 2010 for winForm.

Thank you.

using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Configuration;
using System.Data.SqlClient;

namespace ado01_Connection
{
    public partial class Form10 : Form
    {
        public Form10()
        {
            InitializeComponent();
        }

        private void Form10_Load(object sender, EventArgs e)
        {
            string cs = ConfigurationManager.ConnectionStrings["csDatabase"].ConnectionString;
            SqlConnection con = new SqlConnection(cs);

            using(con)
            {
                //SqlCommand cmd = new SqlCommand("SELECT [CategoryName],[Description],[Picture] FROM [Northwind].[dbo].[Categories];", con);
                SqlDataAdapter da = new SqlDataAdapter("SELECT [CategoryName],[Description],[Picture] FROM [Northwind].[dbo].[Categories];", con);
                DataSet ds = new DataSet();
                da.Fill(ds);

                //BindingSource source = new BindingSource();
                //source.DataSource = ds;
                gwCategory.DataSource = da;// source;
            }
        }
    }
}

Can you try:
gwCategory.DataSource = ds.Tables[0];

Hi eghtebas;

The code snippet should load the control for you.

BindingSource source = new BindingSource();

private void Form1_Load(object sender, EventArgs e)
{
    string cs = ConfigurationManager.ConnectionStrings["csDatabase"].ConnectionString;

    using (var con = new SqlConnection(cs))
    {
        SqlDataAdapter da = new SqlDataAdapter("SELECT [CategoryName],[Description],[Picture] FROM [Categories];", con);
        DataSet ds = new DataSet();
        da.Fill(ds);
        source.DataSource = ds.Tables[0];
        gwCategory.DataSource = source;
    }
}

That is fantastic. I will try shortly but what if I have more than one data adapter?

How can I make reference to an specific data adapter? Perhaps by name?

gwCategory.DataSource = ds.Tables(rdr1);
