A company uses Dynamics 365 Finance.

You create a batch class for the company by using the SysOpefationFramework. The data contract class contains a Boolean and a date field that are displayed in the dialog as a checkbox and date picker field, respectively.

If the checkbox is selected, the date picker field must default to today ' s date unless users manually select a date.

You need to implement the checkbox functionality.

In which class should you implement the functionality?
