怎么取comboBox的ValueMember里面的值

[buzhidao]

DataView dv=db.SqlDataView("select mc,bm from bmk where lb='A'");
this.comboBox1.DataSource=dv;
this.comboBox1.DisplayMember="mc";
this.comboBox1.ValueMember="bm";


我怎么取出来的值是"bm" 而不是001 002 003呀

[panyee]

MessageBox.Show(comboBox1.SelectedValue.ToString());

[雪狼1234567]

private void showSelectedButton_Click(object sender, System.EventArgs e) {
int selectedIndex = comboBox1.SelectedIndex;
Object selectedItem = comboBox1.SelectedItem;

MessageBox.Show("Selected Item Text: " + selectedItem.ToString() + "\n" +
"Index: " + selectedIndex.ToString());
}

[storm97]

comboBox1.SelectedValue.ToString() //ValueMember
comboBox1.SelectedText.ToString() //DisplayMember

[susanyw]

comboBox1.SelectedValue.ToString().Trim();
