How To Show Data In A Label Item?

SqlCeConnection cn = new SqlCeConnection("Data Source=\Program Files\test\tel.sdf");
try
{
SqlCeCommand cmd = cn.CreateCommand();

cmd.CommandText = "SELECT * from phone where PhoneNo = '0912312345'";

SqlCeDataAdapter adp = new SqlCeDataAdapter(cmd);

DataSet ds = new DataSet();

adp.Fill(ds);
this.dataGrid1.DataSource = ds.Tables[0];

label1.Text =Convert.ToString(????????????);

label2.Text =Convert.ToString(????????????);

}

finally
{
if (cn.State != ConnectionState.Closed)
{
cn.Close();
}
}

I can show the result in the DataGrid1

however, I want the label1 to show the Name,

and label2 to show the phoneNo.

how to do in here,

label1.Text =Convert.ToString(????????????);

label2.Text =Convert.ToString(????????????);

thanks
