this is the code:
(tianDataSet is the Dataset created using the designer) (roleBindingSource if the Binding Source created using the designer) tianDataSet.country is the table of countries.
roleBindingSource.DataSource = tianDataSet.country;
dataGridView1.DataSource = roleBindingSource;
dataGridView1.Refresh();
dataGridView1.Update();
It is refreshed but there is no rows there when it happened.
Can you help?
