Is there a way to filter on the raw datawindow rowid? I don't want the row number because it changes when you sort etc. I know you can get the rowid by using GetRowFromRowId, but i would like to have a simple filter like this: rowid in (1,5,7,9,25). I don't want to add my own dummy rowid column, I want to use the rowid that already exists on the native datawindow, but how do you access it?

It ends up working with the rownumber:

Here is the code using PFC, I'll fancy up the code and create a service for this - very slick capability.

It is super fast too.


long   ll_qty,ll_row, ll_Selected[]
string ls_filter
IF IsValid(dw_report.inv_RowSelect) THEN
ll_Qty = dw_report.inv_RowSelect.of_SelectedCount( ll_Selected)
ls_filter = 'getrow() in ('
for ll_row = 1 to ll_qty
if ll_row = 1 then
   ls_filter = ls_filter + string(ll_selected[ll_row])
ls_filter = ls_filter + ','+string(ll_selected[ll_row])
end if
ls_filter = ls_filter + ')'

Depending on the database you are using, you might be able to have a rowid in the resultset itself.

Hi Kim;

FYI ....

  • long ll_rowid
  • ll_rowid = dw_emp.GetRowIDFromRow (dw_emp.GetRow())


Regards ... Chris

Yes, but how do I filter on that ID?

Unfortunately Kim, the GetRowIDFromRow function is not available in the DWO as one that you can use within an expression. Thus, you would need to:

Create a Global Function that uses the GetRowIDFromRow method and expects the Row # as an argument

Create a dummy RowID computed column in your DWO`s SQL

Call the external Global Function using the DWO`s expression GetRow() method to return the RowID from the global function to populate the dummy SQL column in the DWO`s primary buffer. Or do the same in the RetrieveRow event and then do a SetItemXxxx () from there.

Now you can filter on the RowID using the dummy column.
