Text field property

I have a text field i nmy app. If I write "10" in the text field and close the app, then I reload the application and when I focus on the text field I can see all prior entered valued in this text field in a list. I don't like that! How do I prevent this? Is there a property to the textbox which "cleans" the list?i dont know why this would be happening, and im no expert.
i believe it is you own settings in internet explorer

tools
internet options
content
auto complete
:ehh:
This is what I mean:
yes , i believe that is your own setting of internet exploroer.
i.e. if you type in googles search bar, are you greeted with the same drop down list qith ll your previous searches...
Ok, I was not aware of this. Now I have changed the mark in Autocomplete under Forms and everything is ok. But I have to inform all of my users of this :-(
it may be it can be programmed but i am unaware of how,,
perhaps the pragma no cache or something may help,
may be worth a googling if no expert gets back to you here
I don't think this can be changed programmatically. I for one like the feature :D
