[2005] Change tabpage title when user starts editing

[rim78]

Hi all & very good morning!

I have something extra to implement in my form.
You know when you change something in your code in VS, the tab gets a '*' added at the end?
Well, I'd like to do something like that.

I have 4 tabpages; 1 tabpage contains the parent details (textboxes,combobox, etc) and another 3 tabpage with different datagridview.
I'd like the title of the tabpage to change as soon as the user enter something into the controlfield.

What i have so far in my code is not right. I'm sure not implementing the right event for this because when I step through, it didn't go. My questions are:

1) How to know if the user is editing any of the control fields in a tabpage
2) The ideal event to implement this.

Thanks in advance for your time.
