Problem with Remember password

[Sudhanshu Mani Tripathi]

I am using cookies to remember userid and password .It works fine. I am using ImageButton Conrol instead of simple button. my problem is that when i click image button, remembered password is going to blank (IE) In mozilla it not happened but first time button click event is not fired when i click second time then button event fire.(it means we have to click image button two times )
