How is the auto-popup of the list of Items in page 47 "Sales Invoice Subform" ("No." field) achieved? There is an OnValidate trigger (see below) that calls various procedures, none of which, as far as I can see, handle a KeyPress event (as known in .NET) that would load the Items page and filter as the user types the Item-Code. which is what happens.
field("No."; "No.")
{
ApplicationArea = Basic, Suite;
ShowMandatory = Type <> Type::" ";
ToolTip = 'Specifies the number of a general ledger account, item, resource, additional cost, or fixed asset, depending on the contents of the Type field.';
trigger OnValidate()
begin
NoOnAfterValidate();
UpdateEditableOnRow();
ShowShortcutDimCode(ShortcutDimCode);
UpdateTypeText();
DeltaUpdateTotals();
end;
}
I've tried a snapshot debug session and an event recorder session, but I'm still none the wiser. I've used an OnLookup trigger but the user has to click the ellipsis button to display the list of Items. How does it happen automatically?
Any help would be gratefully appreciated.
