Posted on by Community Member

Hi EveryOne,

I have an enum field in my table and that field is having values (None,A,B,C) respectively.

When I open the table and hit (CTRL+N) the enum field by default is selecting the value as (None). But I want it to be go blank when I do the same (CTRL+N). However Should be able to select values manually into the enum field.

Can Some body help me with the x++ code or steps by which I can Accomplish the scenario mentioned above.

with thanks & regards ,

Nishath Salman N.

The default value is the enum element with value 0 (which is None in your case). If you don't want to see an empty string instead of "None", simply change label of the None element.

If the empty value and None represent two different things, create an additional enum element.

It's technically possible to set the field to a value not valid for the given enum (displayed as empty value), but it should be obvious that using invalid values isn't a good practice.

Can you please give me bit more explanation. I am really sorry but very new to ax 2012.

So it is not possible to make the enum field go blank when I hit (CTRL+N) ?.

If possible please give me some sample code ...

I already gave you more than one solution and I don't know which one meets your requirements, because I don't know them.

For example, open the enum in AOT and set Label property of the None element to an empty string.

No, not exactly the same things. Enum element labels are defined at design time and then used by AX kernel.

You could use some workarounds, such as building the combobox control by yourself, but it doesn't look like a good idea.

Since I have added an empty field it is holding three values ( 'Blank Space',Yes, No).

But now I want it to hold just two values YES and NO. However newly added blank Labeled element should also be there but should be displayed in the enum field combo box. Only YES or No should Pop Up ?.

Is there any method to do it ?

If you want to display a different enum than what you want to store in the actual database field, an edit method may be a good solution.

Simply assign a value to the field of the active record, such as MyDatasource.MyEnumField = MyEnum::No;.
