Hi,

When event handlers will be better to use than CoC?

One example i can think of, is if let's say for a certain form, i want to add code for 5 different form controls. In this case creating one event handler class with 5 events is better than creating 5 different classes with CoC. As I will have logic for them in one place.

But if it was only one form control to change, then i can use CoC directly as it's easier to implement in terms i

of code. But still there could come more modifications in the future where i might end with 4 CoCs because i first started with CoC when it was one change only. (Where maybe i can revert back to event handlers or stick with CoC)

What else?

Hi @CU22120935-0

If it's possible you can implement your business logic in table level with COC instead of form control events, so that we can reuse the same for the future customization.

If you are using event handler it will be availble to specific forms control events only.

Hi @Subra,

Thank you, i know that putting code on table level is better than form control. (but i could still use both CoC or event handlers to put code on table level)

My question was when would using event handlers be better than CoC. i could put code on form control using CoC for 5 different form controls or i can do it using event handlers for 5 controls.

i said one advantage might be for event handlers in this case is i could create 1 class for all of those 5 changes while for CoC it will be 5 classes (so that might be a win for event handlers)

In general when would event handlers be better than CoC? other than my example

Also is there a case where event handlers is a must and CoC won't work?
