Usage of CurrPage.SetSelectionFilter()

rcverbeek

Hi,

I have got a question about this standard C/AL code. It is in Page 132 (Posted Sales Invoice):

SalesInvHeader := Rec;
CurrPage.SETSELECTIONFILTER(SalesInvHeader);
SalesInvHeader.PrintRecords(TRUE);

What is the first line of code doing here? It kind of looks like its selectiong only the current record. But if so, why not replace the three lines of code with a single line

PrintRecords(TRUE)

Thanks!

Hello rcverbeek,
only PrintRecords(TRUE) shouldn't work, because u need to apply a filter. That's why you use SETSELECTIONFILTER.

See here:
-> https://docs.microsoft.com/en-us/dynamics-nav/setselectionfilter-function

If you use CurrPage.SETSELECTIONFILTER(Rec), the filter is applied to Rec. So you can't, for example, jump to the next or previous record, because a filter is applied.

The same function should be used in the Page "Posted Sales Invoices (143)".
If you use

Currpage.SETSELECTIONFILTER(Rec);
PrintRecords(TRUE);

The List shows only the selected Records after you trigger that code. You should see that a filter is applied.

Thanks Aluan, this makes sense!

Currpage.SETSELECTIONFILTER(Rec) is same as Record.SETRECFILTER;

It gives you all the filters that is manually selected by the user!
