comboBox数据绑定问题。

private void Form1_Load(object sender, EventArgs e)
{
OleDbConnection con = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Documents and Settings\danzhao\My Documents\db1.mdb");
con.Open();
OleDbDataAdapter adr = new OleDbDataAdapter("select Province from Province",con);
DataSet da = new DataSet();
adr.Fill(da,"adr");
comboBox1.DataSource = da.Tables[0].DefaultView;
comboBox1.DisplayMember = "Province";
con.Close();
}

private void button1_Click(object sender, EventArgs e)
{
textBox1.Text = comboBox1.SelectedItem.ToString();
}
单击按扭后，为什么textBox1中显示的是System.Data.DataRowView而不显示绑定数据的字段？

获取值应该使用 SelectedValue
