You already asked where to put the code in your previous thread, Form Input : Convert small letters to Capital letters, and I replied to the question. Please the read the response there.

I'm sorry, but I don't see any question nor a problem description in your reply, just "when the user changes field is also ok .. at the time of saving is also ok...".

"Where can I write the code??" -> in the modified method of the Mac Address field's FormControl, or FormDataSource Field.

"tell me how" -> by right clicking on the Methods node of the 2 options above, selecting the method to override, then typing the code on your keyboard.

Well, the best practice is putting the business logic to table, not to a form, to make it reusable and easier to upgrade. And as I explained in them other thread, the right place depends when the logic is required to run. Doing it immediately when a field is modified is one option I mentioned there, but it's not only possibility.

It would be great if this single discussion wasn't spread to several threads; people either loser information or it must be duplicated. I (or some other moderator) probably should have locked this thread straight away.

You either read it from the form control:

msdn.microsoft.com/.../formstringcontrol.text.aspx

msdn.microsoft.com/.../formcontrol.valuestr.aspx

Or from the FormDataSource table.field, depending on how did you implement it. On the form like I gave one solution for you, or in a more generic place like Martin also suggested.

I suggest you stop your complains and random short questions and switch to a more systematic approach that gives you better chance to understand how to design a technical solution for your business requirement.

Start with explaining what business logic you're actually trying to implement.

If I combine pieces you mentioned in your last four threads, it looks like you want allow users to type in a MAC address, you want to validate it and then storing it in database in a different form. If it's the case, there is no requirement to have two fields and copying between them; there will be just one field in database.

I didn't answer how to "how to copy the field" because you didn't explain what you mean by that it seems to me that you talk about it just because you don't understand how to design the technical solution correctly. Maybe you have a reason for it, but you can't expect to know it if you don't bother to share it with us.
