How to Update flowField Automatically when the other field

(0) ShareShare
ReportReport
Posted on by muaz deyab 90

I have flowField in the header which is the sum of the amount in lines but it does not update automatically, it updates  when I refresh the page .

How can I make it update automatically.

I tried doing this 

Header.get(rec."Document Type", rec."Document No.");
HeaderPage.SetRecord(Header);
HeaderPage.SetTableView(Header);
HeaderPage.Close();
HeaderPage.Run();
on validate 
is there any way to make sure that  flowfield is updating automatically without reopening the page ?
and page.close is not working does anyone have any idea about that?

    Hi,

    In earlier version of NAV we have a command which can be Stroke a Refresh button key (F5), using 'Windows Script Host Object Model'.WshShell .Net library

    CREATE(WshShell);

    WshShell.SendKeys('%{v}');

    CLEAR(WshShell);

    but I in SaaS version, as I know this is not available unfortunately. You can either write a code on OnafterGerRecord trigger of header Page or  press F5 manually.

    Hi, did you find no change in this Flowfield value after modifying any field?

    I feel that using Page.Update([Boolean]) Method  can solve this problem.

    More details:

    https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/methods-auto/page/page-update-method

    Or, using Record.CalcFields(Any [, Any,...]) Method directly.

    https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/methods-auto/record/record-calcfields-method

    Hope this helps as well.

    Thanks.

                           Header.CalcFields("HCB-Total Exc. VAT (LCY)", "HCB-Total Incl. VAT (LCY)");

                           // // HeaderPage.Editable := false;

                           // HeaderPage.Run();  I tried this but the page did not close

                       end;

                   }

    Hi,

    Move this code into Subform's OnValidate of Quantity field, and there write a line currpage.update.

    Thanks.
