need to send an email only to the records that the user selects in a list page. What is the recommended way to capture the selected lines in a page so I can loop through them and pass the data (e.g., email addresses) into my mail-sending function?

Hi,

Use CurrPage.SetSelectionFilter on an action. It captures only the user‑selected rows into a record variable (same table), which you can loop and pass to your mail function.
actions
{
    action(SendEmails)
    {
        Caption = 'Send Emails';
        Image = Email;
        ApplicationArea = All;
        Promoted = true; PromotedCategory = Process;

        trigger OnAction()
        var
            Sel: Record "Customer"; // use your page's source table
        begin
            CurrPage.SetSelectionFilter(Sel);
            if Sel.IsEmpty() then
                Error('Select at least one row.');

            if Sel.FindSet() then
                repeat
                    if Sel."E-Mail" <> '' then
                        SendCustomerMail(Sel."No.", Sel."E-Mail"); // your function
                until Sel.Next() = 0;
        end;
    }
}
Notes

Ensure the list page allows multi‑select (default is allowed on List pages).

If you want to process elsewhere, pass Sel (with its selection filter) or copy keys to a temp table/list.

Hi,

Use the built-in CurrPage.SetSelectionFilter to capture only the selected records.

Example:

trigger OnAction()
var
RecSelected: Record Customer;
begin
CurrPage.SetSelectionFilter(RecSelected);
if RecSelected.FindSet() then
repeat
// Your email-sending logic here
SendEmail(RecSelected."E-Mail");
until RecSelected.Next() = 0;
end;

This ensures only the records the user selected on the list page are processed.

Thanks

Rishabh

Hi

Use CurrPage.SelectionFilter in a multi-select list page to loop through only the user-selected lines and pass their data to your function.
