How to mark a ComboBox field as mandatory

Posted on by delarosaau

Dear Dynamics community,

I have (hopefully) a simply-answered question:
In the below form I have a field "Freight Responsibility" that has an enum backing the field on the table. I've made the field on the table required, the field on the data source required, tried to make the field mandatory through code, and I still cannot get the field (a combobox) to highlight with a red surround when the form loads as 'required.'

Any suggestions?

Hi delarosaau,

With version 10.0.0.12 it is possible to make fields mandatory using personalisation.

You can refer to:

henrikmarxlarsen.wordpress.com/.../

or you can add the datasource.object(fieldnum(table,field1)).mandatory(true) in the validataWrite() method of your form datasource;

regards

Enum shouldn't ever be empty - it always has one of its element as the value.
