How to write code on modified of a segmented entry control?

(0) ShareShare

Posted on by Bhagyashree Dave 133

Hello all,

I have a requirement, according to which, I have to run some validations while changing the value of a segmented entry control, which is on Vendor payment journal, as shown in the image.VendPaymJour.png

I have been trying to write code on modified of the form control, modified of form data field, event handler of form control, validate method, but it isn't working.

I debugged the code each time, but the debugger isn't triggering.

Am I doing anything wrong? or is there any other way to write code on modified of the segmented entry control?

Thanks in advance,

Bhagyashree Dave

    The behavior is driven by the controller class, e.g. LedgerDimensionAccountController.

    You can either utilize or extend existing capabilities, or you can create create a custom, specialized controller (and override validateCombination(), for example).

    By the way, putting validation to OnModified would be wrong even for normal controls - validation needs to be done before modification.

    Hi,

    Thanks for replying.

    I created extension of the controller class, and wrote my code in validate method, and it worked.

    Thanks again.

    Hi Martin,

    What makes this specific control special?  This is a general question not related to wanting to put validation code here.  This control by itself has modified / lookup methods on the standard form.  What prevents us from using chain of command on the modified method of the control.  When debugging you will hit those methods on the form, just none of the chain of command calls.
