Re: Page_Load method issues with Back Button

Sridhar,

Off the top of my head here's the way I think I'd try first:

Create a hidden filed on the form that can hold a value which will tell your
startup script if it should run or not. Just before the script does the
redirect set the hidden field to a different value. I believe that when the
back button is clicked the hidden field will retain the new value and may be
used to keep the script from running.
