I have a DataGrid, and I want to populate it with data from a table in my SQL 2005 database.

As this is all rather new to me can anybody provide code as to how I can populate it (columns being created etc)?  I will be calling a select stored procedure I have made.

//C# windows application code, 
 
 //create connection to database
            System.Data.SqlClient.SqlConnection conn = new System.Data.SqlClient.SqlConnection();
            conn.ConnectionString = "Data Source=.;Initial Catalog=AdventureWorks;Integrated Security=True";
            conn.Open();
 
            //setup SqlCommand and assign SQL query in command
            System.Data.SqlClient.SqlCommand command = new System.Data.SqlClient.SqlCommand();
            command.CommandType = System.Data.CommandType.StoredProcedure;
            command.Connection = conn;
            command.CommandText = "spProduct";
 
            //create one data adapter which will execute the command and fill the data into data set
            System.Data.SqlClient.SqlDataAdapter recordAdp = new System.Data.SqlClient.SqlDataAdapter();
            recordAdp.SelectCommand = command;
            System.Data.DataSet recordSet = new System.Data.DataSet();
            recordAdp.Fill(recordSet);
            command.Dispose();
            conn.Close();
            
            //datagridview1 should be on the form
            dataGridView1.DataSource = recordSet.Tables[0].DefaultView;

Hi RiteshShah

I have tried to modify that code (as it's using a different grid, and is ASP whereas I'm making a windows app) to the following:

SqlConnection conn = new SqlConnection(ConfigurationManager.AppSettings["SQLConnectionString"]);
            SqlCommand cmd = new SqlCommand("dbo.[sUsersSelect]", conn);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Connection.Open();
           
            grdAdminResult.DataSource = cmd.ExecuteReader();
            cmd.Connection.Close();
            cmd.Connection.Dispose();

But I get an exception on the ExecuteReader:
Complex DataBinding accepts as a data source either an IList or an IListSource.
