Solution 1

PHP

autocomplete="off"

is the argument that you are searching for. add it to your textbox and you'll succeed.

Unfortunately not supported in all versions of major browsers (not sure if latest ones support it properly) and it wont stop browsers such as IE and Chrome offering to save passwords which overrides traditional autocomplete - in other words, its the official solution but unofficially there isn't really a proper solution.... Could always use javascript to keep the password box empty until user actually starts typing in it (combination of change and keydown events would do!) Anyway, good answer, my 5.

you mean to implement a custom text? hmm, could be better, yes.
But does the Listener implementation cause the text to flicker around?

Ed Nutting 6-Feb-12 8:34am

It might do...but then again I haven't tried... In something like Chrome I doubt it would because its JavaScript engine and Rendering engine are both incredibly fast (by browser standards). However, something like IE 9 or 8 (not even gonna consider 7 or 6) would flicker - everything seems to flicker in those. But it still might be an improvement upon having stuff appear. Personally I wonder why OP wants to block auto fill - it usually means you are trying to do something the wrong way.... Auto fill is available to users for a reason...

hmm, it's the Username text for a login. I guess he's trying to level up the security in not giving hints on the username.

Ed Nutting 6-Feb-12 11:08am

So how's he going to make user not store details in plain text files I wonder? ;P

Solution 2

Hi,
Just want to add more...
If you want to disable autofill on all controls at the page, use autocomplete="off" on form:

ASP.NET

<form id="Form1" method="post" runat="server" autocomplete="off"></form>

plz find this

Try:
<asp:textbox id="MyTextBox" autocompletetype="Disabled" runat="server" xmlns:asp="#unknown">

this renders as:
