Did you figure this out?

Hi Ian,

We ended up doing this manually in Commerce Manager in all environments.

Administration -> System Settings -> Business Foundation -> Contact -> Forms tab -> View Form.

After adding the metafields to the metaclass you can add the field to the desired form by code as well.

The function to use is:
FormController.AddMetaPrimitive(string metaClassName, string formName, string fieldName)
(Mediachase.BusinessFoundation.MetaForm.FormController)

The Form names are:

Edit Form -> [MC_BaseForm]
Short Info Form -> [MC_ShortViewForm]
View Form -> [MC_GeneralViewForm]

If you wish to do it in a more controlled manner, for example deciding where in the form to put the field, its span, border, label etc you can use the FormDocument instead.

var forms = SqlFormDocumentManager.GetFormDocuments(className) will load all forms for a meta class

var theForm = forms.FirstOrDefault(x => x.DocumentType == "[MC_BaseForm]") 

DocumentType can be used to determine which form you wish to edit, and the form object you end up with will give you access to all rows, columns, sections, controls and items.

SqlFormDocumentManager.Save(theForm) will save your changes.

So to add a meta field to a form you'd need to do something like this.

var newField = new FormItem()
        {
            RowIndex = 0, // Will be placed first
            CellIndex = 1,
            RowSpan = 1,
            ColSpan = 1,
            BorderType = 0,
            ShowLabel = true,
            LabelWidth = "120px",
            Uid = Guid.NewGuid().ToString("N")
        };

        newField.Labels.Add(new FormLabel("My label:", "en")); // Add a label
        newField.Control = new FormControl("MetaPrimitive") // Add the control for the field
        {
            Source = "SourceFieldName",
            ReadOnly = false,
            Uid = Guid.NewGuid().ToString("N")
        };

        theForm.FormTable.Rows[0].Cells[0].Sections[0].Control.Items.Add(newField); // Adding the field to the first section, first cell, first row
        SqlFormDocumentManager.Save(theForm);

Just a note:

var forms = SqlFormDocumentManager.GetFormDocuments(className) 

will return 0 elements, if you still have default form and only starts returning it if there are some modifications in form(at least for Organization in epi comm 13.19)

Hello,

We recently had a support case related to this area. The following steps will be resolved it. 

        private void CreateMetaField(string metaClassName, string metaFieldName, string friendlyName,
            bool isNullable = true, int maxLength = 255, bool isUnique = false)
        {
            var metaClass = DataContext.Current.GetMetaClass(metaClassName);
            if (metaClass == null)
            {
                return;
            }
            var fieldExists = metaClass.Fields.Contains(metaFieldName);
            if (fieldExists)
            {
                return;
            }
            using (var metaFieldBuilder = new MetaFieldBuilder(metaClass))
            {
                metaFieldBuilder.MetaClass.AccessLevel = AccessLevel.Customization;
                metaFieldBuilder.CreateText(metaFieldName, friendlyName, isNullable, maxLength, isUnique);
                metaFieldBuilder.SaveChanges();
            }

            //Add metafield to form.
            AddMetaFieldToForms(metaClassName, metaFieldName);
        }

        private static void AddMetaFieldToForms(string metaClassName, string metaFieldName)
        {
            string[] formNames = { FormController.BaseFormType, FormController.GeneralViewFormType, FormController.ShortViewFormType };
            foreach (var formName in formNames)
            {
                FormController.AddMetaPrimitive(metaClassName, formName, metaFieldName);
            }
        }

Then you call to CreateMetaField() method where you want like this:

            //Add custom meta field to contact form programmatically.
            CreateMetaField(ContactEntity.ClassName, "ContactTest_Name", "ContactTest_FriendlyName");

The new control with labeled "ContactTest_FriendlyName" will be showed in "Contact" form in CommerceManager.
