为什么结果listBox1中显示的是:System.Data.DataRowView呢?

[myskyfeifei]

listBox1.DataSource=dsEp.Tables["Employees"];;
listBox1.DisplayMember="empname"; //empname是表Employees的字段

为什么结果listBox1中显示的是:System.Data.DataRowView呢?
请指教!

make sure "empname" is indeed Employees的字段, the following works for me


SqlDataAdapter da = new SqlDataAdapter("select * from employees",
"server=localhost;database=northwind;uid=sa;pwd=;");

DataSet ds = new DataSet();
da.Fill(ds,"Employees");

listBox1 = new ListBox();
listBox1.Location = new Point(100,100);
listBox1.DataSource=ds.Tables["Employees"];
listBox1.ValueMember="EmployeeID";
listBox1.DisplayMember="LastName";
Controls.Add(listBox1);
