ADO.NET Data Binding Examples

An example shows how you can create a DataTableReader and bind it to a DataGridView

using (SqlConnection cn = new SqlConnection(cnStr)) {
SqlCommand cmd = new SqlCommand(sqlAllCustomers, cn); SqlDataAdapter adpt = new
SqlDataAdapter(cmd); DataTable dtCustomers = new DataTable("Customers");
adpt.Fill(dtCustomers); DataTableReader dtRdr = ds.CreateDataReader();
dgvCustomers.DataSource = dtRdr;
}

Load method of a DataSet or a DataTable, you can pass in a DataTableReader or any reader class that implements the IDataReader interface.

DataTableReader dtRdr = dt1.CreateDataReader();
DataTable dt2 = new DataTable();
dt2.Load(dtRdr);

DataSet can be filled from the Products table of the Northwind database.
string sSQL = "SELECT * FROM Products";
string sConnString = "Server=(local);Database=Northwind;Integrated Security=SSPI;";
SqlDataAdapter oDa = new SqlDataAdapter();
DataSet oDs = new DataSet();
using(SqlConnection oCn = new SqlConnection(sConnString))
{
SqlCommand oSelCmd = new SqlCommand(sSQL, oCn);
oSelCmd.CommandType = CommandType.Text;
oDa.SelectCommand = oSelCmd; oDa.Fill(oDs, "Products");
}
