How to return the enum value and description from a base enum and populate a dropdownlist in ASP.Net

(0) ShareShare

Posted on by Robert Herrmann 790

I'm new to AX development.  I am using AX 2012.  I have a class which is used by a web service to expose it's methods to an ASP.Net web site project.  The web service works fine.

On my web page, I have a dropdownlist control.  I want to create a method in my AX class which will return a list that populates my dropdownlist control.  I have not used enums and I'm not sure how to do this.  So I want to return rows of enums / descriptions that will populate my ASP.Net dropdownlist control.  How can I do this?

    Hi Robert

    In the link below, you can find the x++ code for get values of base enums.

    You can create a list of elements to return to your ASP.net application.

    Hi Denis,

    I verified your answer a week or 2 ago but I actually have a syntax error when I use the code in the link you provided.  Here is my code:

    private void getTareTypes()

    {

       EnumId     enumId = enumNum(wfsTareType);

       DictEnum  dictEnum = new DictEnum(enumId);

       int                count   = dictEnum.values();

       int                counter;

       for(counter = 0; counter < count; counter ++)

       {

           dictEnum.name(counter);

       }

    This line is underlined in red and says there is a syntax error:

       int                count   = dictEnum.values();

    So what I am I doing wrong?

    AX 2012 offers the Metadata service for this purpose, namely operations GetEnumMetadataByID and GetEnumMetadataByName. You'll get EnumMetadata object and you'll find enum elements in Entries.
