Dynamics 365 Business Central: About the automatic filtering problem after using Page.SetSelectionFilter Method

Hi, Readers.
Today I would like to briefly share a question I saw yesterday in the Dynamics 365 Community, Page – Filter Reset – after printing (dynamics.com).
What is the problem? The developer wants to print the selected assembly orders. Here’s his code.

We have discussed Can we change default options/filters on the request page of Report??? before, he used one of these methods. But there was a problem. When he finished printing and returned to the list page, the list page only showed the row he had just selected (Filters are automatically added). Why? This actually has nothing to do with the printed report, but has to do with the following two factors.

1. Page.SetSelectionFilter(var Record) Method: Notes the records that the user has selected on the page, marks those records in the table specified, and sets the filter to “marked only”.

2. System-defined variables:

Let’s look at a simple example. Add a action to the Item List page to count the selected items.

You will find that the page has been filtered at this time.

So how do we solve this problem? It’s simple. Instead of using the system variable, Rec, declare a new variable.

Great.

And, there is another simple way, which is just to reset the filters of the Rec at the end. This results in the same thing as declaring a variable.
More details: Record.Reset() Method

PS: Dynamics 365 Business Central: How to remove or cancel only one filter (Not Reset All filter)

If the variable you declare is a temporary table, please note that you need to insert data in advance.
Give it a try!!!😁

END

Hope this will help.

Thanks for reading.
