Hi all,

Thanks in advance!!!

I have a requirement where I want to make a field for a particular record non editable based on another field value. The form name is LedgerPeriodCloseProjectTaskListPage
and the data source used is LedgerPeriodCloseProjectTask. But the catch is the combo box (Tick mark) control which I want to make editable/noneditable is not having a field at table level and the data filled in it is based on the form data source method of the same table; The name of the control is 'IsComplete'. And field on which the editable/noneditable property of the 'IsComplete' control should be dependent is my custom field of BaseEnum type where if the element value of the Enum is 'Submitted' then only the 'IsComplete' should be non editable or else editable!

This is the form where the Completed tick value for a particular record should be non editable if the Workflow status value for the same record is Approved!

Thanks in advance!!!

Do you have any particular problem or are you saying that you don't know anything - how to use enums, how to access a field value, how to make a control read-only and so on?

Before you explain your actual problem, let me give you a few hints:

Call your code from active() method of the data source (create a CoC extension of the data source) or from a more specific method called from active() (it depends on the form implementation).

Get the control you're interested in by name: element.IsComplete.

Use its allowEdit() method to make it editable or non-editable.

Your condition will be something like ledgerPeriodCloseProjectTask.MyField == MyEnum::Approved.
