Usage of CurrPage.SetSelectionFilter()

Neelam_Arya

Hi, I want to use CurrPage.SetSelectionFilter() to pick the current selected record on a lookup page as the page has composite primary keys.
The question is can I do that? And where to write the function? Page? Table? Inside the definition of the lookUp field?

Thanks in advance.

Normally you want that to perform some action, so in that action. Is a page action so on the page.

SETSELECTIONFILTER uses MARKs top mark records selected on the page.

The PK structure of underlying record does not matter, as you would normally use SETSELECTIONFILTER like this:

CurrPage.SETSELECTIONFILTER(a_record_var_of_the_same_type_as_page_source_record);
a_record_var_of_the_same_type_as_page_source_record.MARKEDONLY(TRUE);
IF a_record_var_of_the_same_type_as_page_source_record.FINDSET THEN
REPEAT 
 // do your stuff with selected a_record_var_of_the_same_type_as_page_source_record one by one
UNTIL a_record_var_of_the_same_type_as_page_source_record.NEXT=0

I answered that question in your other thread.

What is "the lookUp field" supposed to be?

Since the function is called through (as a method of) CurrPage, the only place you can call it from is the page, because CurrPage only exists there.

Usually you call the containing code block either from an Action on the page itself, or you call it from a page variable anywhere by way of a global procedure in the page object.

By the way, SETSELECTIONFILTER uses marks in most cases, but not if either only one record was selected, or if all records within the filter were selected. SETSELECTIONFILTER turns MARKEDONLY on or off as needed. So, in generall, don't mess with MARKEDONLY after you have called SETSELECTIONFILTER.

And there's another mistake in Slawek's example code: MARKEDONLY works like a property of an object. Used as in the example code, it just returns it's current value. To set the filter use MARKEDONLY(TRUE) or MARKEDONLY := TRUE

Thank's @Vaprog, I've edited it.

CurrPage - Its clearly saying Page so you cant use it in Table
