Hi Good Guys,
I am learning how to use C#Net2008 to develop Window Application. I was a VB.NET2008 developer. I need your help, Please Help me.

I am encountering 2 problem trying to fill LISTBOX with DATASET and CATCH to display error message.

In the LISTBOX dropdown list instead of displaying CUSTOMERNAME, it display System.Data.DataViewManagerListItemTypeDescriptor

private void FLoadListBox()
            string strSql  = "Select CustomerID, CompanyName from  Customers Order by CompanyName";
            sqlconn = new SqlConnection(connstr);
            sqlDA = new SqlDataAdapter(strSql, sqlconn);
            DS = new DataSet("DS");

                DS.CaseSensitive = true;

                // fill listbox
                this.listBoxCust.DisplayMember = "CompanyName";
                this.listBoxCust.ValueMember = "CustomerID";
                this.listBoxCust.DataSource = DS;
            catch (SystemException MsgException)

Thank you .

Qualify the fields.

this.listBoxCust.DisplayMember = "Cust.CompanyName";
this.listBoxCust.ValueMember = "Cust.CustomerID";
this.listBoxCust.DataSource = DS;
