Populate a datagrid view using SQL C#

Question

Hi,

I have a database with a few tables in, one being "Customers"

I don't know how to fill the datagrid with the Customers table contents
I need to be able to display that table in a datagrid view on the click of a button on my customers search form

I will eventually be able to search by name, post code, city and ALL which is what i need to do first

I think I have tp use data adapters and data sets but I'm not exactly sure how to use them with SQL to get the results I want

I am using SQL Server 2005, Visual Studio 2008 and C#

Any help would be appreciated

Thanks

        private void cmdSearch_Click(object sender, EventArgs e)
        {
            SqlConnection sqlNWConn = new SqlConnection();
            SqlDataAdapter daCustomers;
            DataSet dsCustomers;
            String tableName = "Customers";

            sqlNWConn = new SqlConnection(@"Data Source=DANS-MAC--WIN7\SQLEXPRESS;Initial Catalog=Northwind;Integrated Security=True");

                    if (radioAll.Checked == true)
                    {
                        try
                        {
                            sqlNWConn.Open();
                            dsCustomers = new DataSet();                                                // Creates a new DataSet
                            daCustomers = new SqlDataAdapter("select * from Customers", sqlNWConn);     // Creates a new SqlDataAdapter with select command and connection
                            SqlCommandBuilder cmdBldr = new SqlCommandBuilder(daCustomers);             // Fills in insert, update, and delete commands
                            daCustomers.Fill(dsCustomers, tableName);                                   // Fills the dataset
                            dataGridCustomers.DataSource = dsCustomers;
                            dataGridCustomers.DataMember = tableName;
                        }
                        catch
                        {
                            MessageBox.Show("there was an error and your code is crap"); // error will be changed when working
                        }
                    }

                    if (radioName.Checked == true)
                    {
                          // Searches value in txtSearch in table Customer ContactName
                    }
          }

You seem to be feeling panicked. Have a little fun with Database Table Update in a DataGridView without Writing Code.
