Hi Sadhu,

As promised, I had a look at how to accomplish the
same thing without (too much) scripting. Here's what I
found:

- use the query builder to create the same query twice
(otherwise you get refresh issues) ; name them
PortalQuery and DetailQuery
  SELECT * FROM locations ;

- now create a new field and make it a table object ;
use the database panel to hook it up to the
PortalQuery and for columns pick "Show all"

- now create the other fields and uise the database
panel to hook them up to DetailQuery and pick the
separate columns.

- to round it all off, you'll want to update the
DetailQuery fields whenever you select a different
line in the PortalQuery table field ; so set its
script to (as usual, watch for wrappings):

  on selectionChanged
    put the hilitedLines of me into tNumber
    put the cREVDatabase["queryobject"] of fld
"DetailField1" into tObject
    put revQueryLongName(tObject) into tObject
    if exists(tObject) and the
cREVGeneral["databasequeryobject"] of tObject is true
then send "revGoToRecordOfQuery" && tObject & comma &
tNumber
  end selectionChanged

- of course you'll have to employ in your PortalQuery
field the tricks I mentioned earlier to get the
arrowKeys, etc.

Hope this helped,

Jan Schenkel.
