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
{
publicCommon lookupReference(FormReferenceControl_formReferenceControl)
{
returnDirUtility::buildAffixReferenceControlLookup(_formReferenceControl, DirNameAffixType::PersonalPrefix);
}



}




Here is the code through this we create extension.


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

}




Here is the code through this we override the method.




[ExtensionOf(formDataFieldStr(HcmWorker, DirPerson,PersonalTitle))]
finalclassDemo_Extension
{
publicCommon lookupReference(FormReferenceControl_formReferenceControl)
{
next lookupReference(_formReferenceControl);
returnDirUtility::buildAffixReferenceControlLookup(_formReferenceControl, DirNameAffixType::PersonalPrefix);
}



}


Now perform build in sync on your module. enjoy
