System.Data.DataViewManagerListItemTypeDescriptor Combobox

Your bindings for the ComboBox are not complete, you want something like
this I believe:

//DataViewManager provided through the DataSet.DefaultViewManager
property
this.comboBox1.DataSource=ds.DefaultViewManager;

//display "someTable.SomeID" value in the ComboBox
this.comboBox1.DisplayMember="someTable.SomeID";


Where 'someTable' and 'someTable.SomeID' are replaced with the value you
require.

No, still comes up with error in combo box.
this.cboPrivilege.DataSource = ds.DefaultViewManager;
this.cboPrivilege.DisplayMember = "SALES_REVENUE.LICENSE_CODE";

Hi Cadel,

Please try to change cboPrivilege.DataSource = ds; to

this.cboPrivilege.DataSource = ds.Tables[0];
this.cboPrivilege.DisplayMember = "SALES_REVENUE.LICENSE_CODE"; //if
SALES_REVENUE.LICENSE_CODE is the column name.

Kevin your right again. I had the table name AND the column name like Ollie
told me, but when I just have the column name it worked.

Thanks.
