Use textfield subclass in place of activecell


I have a text field subclass (used to enter dates or times) that I’d like to use in place of an active cell on a listbox.

I have moved most of the functionality to the listbox using cell key down, cell click, cell lost focus etc… but it’s just not working the same.

Is it even possible to use a subclass of textfield like this? Or should I keep working at making it work in the listbox itself?

Thank you!

The problem is I am having difficulty accessing the SelChanged event of the active cell. Does anyone have experience making that work?
