//Initializing:
dTable = new DataTable();
dataAdapter.Fill(this.dTable);
dView = new DataView(dTable);
dataGridView1.DataSource = dView;

private void tsBCopy_Click(object sender, EventArgs e)
{
int copyCount = Convert.ToInt32(tbCopyCount.Text);
DataRowView[] newRows = new DataRowView[copyCount * dataGridView1.SelectedRows.Count];
for (int i = 0; i < dataGridView1.SelectedRows.Count; i++ )
{
newRows[i] = (DataRowView)dataGridView1.SelectedRows[i].DataBoundItem;
}
// And now I will change the primary Key in the newRows and Add it to the DataTable
}
