WinForm 2.0 有代码两个DataGridView实现Master/Details

private void GetData()

// Specify a connection string. Replace the given value with a

// valid connection string for a Northwind SQL Server sample

// database accessible to your system.

// Add data from the Orders table to the DataSet.

SqlDataAdapter detailsDataAdapter = new

SqlDataAdapter("select * from Orders", connection);

detailsDataAdapter.Fill(data, "Orders");

// Establish a relationship between the two tables.

DataRelation relation = new DataRelation("CustomersOrders",

data.Tables["Customers"].Columns["CustomerID"],

data.Tables["Orders"].Columns["CustomerID"]);

data.Relations.Add(relation);

// Bind the master data connector to the Customers table.

}

catch (SqlException)

"connectionString variable with a connection string that is " +

"valid for your system.");
