Form Data Source Field Method Override D365FO

Form Data Source Field Method Override D365FO

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

Here is the annotation code to create COC

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

In this demo, we are using the 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 the Hcmworker form 

 [DataField]

        class PersonalTitle

        {

            public Common lookupReference(FormReferenceControl _formReferenceControl)

            {

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

            }

        }

Here is the code through which we create extensions.

[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);

    }

}

Now perform build in sync on your module. enjoy

Form Data Source Method override COC D365FO

Form Data Source Method override COC D365FO

Here is the sample how can you override the form data-source event.

In this demo we have created the extension of HcmWorker form data-source (HcmWorker).

Here is the original method  of HcmWorker data-source 

    public boolean validateWrite()

        {

            boolean ret;

            ret = super();

            if (ret)

            {

                partyForm.validateWrite();

            }

            return ret;

        }

Here is the  code to create form data-source extension class 

[ExtensionOf(formdatasourcestr(HcmWorker, HcmWorker))]

final class Demo_Extension

{

}

Here is the code to override the data-source method through COC.

[ExtensionOf(formdatasourcestr(HcmWorker, HcmWorker))]

final class Demo_Extension

{

    public boolean validateWrite()

    {

        boolean ret;

        ret  =  next validateWrite();

        if (ret)

        {

                    

           /// do your code here

        }

        return ret;

    }

}

In last perform Build & Sync.
