10) Form Data Source Field Method Override D365FO

Form Data Source Field Method Override D365FO

In this demo I will show to create extension class of form data source Field class and override method thorough COC.

Here is the annotation code to create COC

[ExtensionOf(formDataFieldStr(FormName, DataSourceName,DataFieldName))]

In this demo we are using HcmWorker form and creating Extension of DirPerson Data source field Personal Title..

[ExtensionOf(formDataFieldStr(HcmWorker, DirPerson,PersonalTitle))]

In actual code you can find the method in Hcmworker form 

 [DataField]

        class PersonalTitle

        {

            public Common lookupReference(FormReferenceControl _formReferenceControl)

            {

                return DirUtility::buildAffixReferenceControlLookup(_formReferenceControl, DirNameAffixType::PersonalPrefix);

            }

        }

Here is the code through this we create extension.

[ExtensionOf(formDataFieldStr(HcmWorker, DirPerson,PersonalTitle))]

final class Demo_Extension

{

}

Here is the code through this we override the method.

[ExtensionOf(formDataFieldStr(HcmWorker, DirPerson,PersonalTitle))]

final class Demo_Extension

{

    public Common lookupReference(FormReferenceControl _formReferenceControl)

    {

        next lookupReference(_formReferenceControl);

        return DirUtility::buildAffixReferenceControlLookup(_formReferenceControl, DirNameAffixType::PersonalPrefix);

    }

}
