suppose customer_name is displaymember and customer_id is valuemember ...........
you can have it by..........

 
Dim custid As String =CType(cmyCombo.SelectedValue,String)
 

if valuemember is not set.....then you can have it by .........

 Dim custid As String = CType(myCombo.SelectedItem, DataRowView).Row("customer_id ")

Sometimes (as is the case with a dataset)
the SelectedValue property returns an entire Row instead of just what is defined as the "valuemember".
You could check this by saying:

MessageBox.Show(mycombobox.SelectedValue.GetType().Name);
 

That will tell you the name of the object it is returning, which frequently sheds some light on the problem.
