preview

I have a WPF textbox, and perform the following actions

Enter text as "12345"
Move cursor between 3 and 4 (using arrow or mouseclick)
Enter 0 (so Text is now "123045")

Which event/eventargs can tell me that 0 was typed at location 4. I need to know this at Preview level so that I can reject the character 0 based on the prefixed and suffixed digits.
