Binding data to comboBox question

Hello everybody

Why I try to binding data from sqlserver to a comboBox that display System.data.dataRowView in the comboBox?

Using following codes
string sQueryDetailCatalog = "Select dname from DetailCatalog where gcode = '"+sGenCode+"'"
PMda1.SelectCommand.CommandText = sQueryDetailCatalog

try
PMConnection.Open()
PMda1.TableMappings.Add("Table1","DetailCatalog")
PMda1.Fill(PMds1);
comboBox2.DataSource = PMds1.Tables["DetailCatalog"]
comboBox2.DisplayMember = "dname";
}Catch(Exception E_SQLEEOR

er.vWrLog(E_SQLERROR); // Write error messages to log file

finall

PMConnection.close()
I don't know why or how can I display correct value in the comboBox ? Surprising , the things doesn't happen in every form. Can you help me ? Thankyou
