On my web page I have a textbox in which the doctor enters a patient ID. A dropdown list is populated with the avaliable test dates when he enters a patient id and hits the Enter key. There are several other buttons on the page that allow him to pull up different test panels based on the patient id and date. Both the patient id and date are set as session variables. I figured out how to display a java box asking to select a date if he forgets(after entering a patient ID)and selects one of the panels first. My question is how do set the Session variable for Patient ID to " " on the initial page load without it resetting to " " every time the page reloads?
Maybe IsPostBack or something along those lines?
Thanks
