Dropdown box as a field in an Ultragrid...

Hi,

I have an ultragrid bound to a data source which is pointing to a query handle via a temp table.

DEFINE TEMP-TABLE ttGrid
    FIELD field1 AS CHAR LABEL "Document Grouping".

DEFINE PRIVATE QUERY qu_Grid FOR ttGrid SCROLLING.

    CREATE ttGrid.
    ASSIGN
      ttGrid.field1 = "sdasd".

    CREATE ttGrid.
    ASSIGN
      ttGrid.field1 = "sdasd".

    OPEN QUERY qu_Grid PRESELECT EACH ttGrid NO-LOCK.

    IF TEMP-TABLE ttGrid:HAS-RECORDS THEN
    DO:
      bindingSource1:AllowEdit = FALSE.
      bindingSource1:HANDLE    = QUERY qu_Grid:HANDLE NO-ERROR.   
    END.

I also have a drop-down combo populated in a similar manner. My question is: How do I set my grid field as a combo type and have it display the combo data?

The examples I have found so far on the net don't seem to work or require the filed to be "un-bound".

Any help would be greatly appreciated.

Thanks,

Saquib.
