What is the right Answer? some of them said using VF page we can Do... Some of them said using formula fields and Create interview score field with data type of radio button....


Please reply correct answer ... Explain it.....


The current data types in SF doesn't support 'Radio Button' data types. If the requirements needs to be displayed as a radio button then VF page will be my best bet.  And as we have only 5 radio buttons to choose from so we don't need any validation rule on this field. I am still to find out how it works with formula field with 'radio buttons'.
