    Hello, I have a RadTabStrip
    This screen calls default.asp
    It contains a button that calls the registration screen
    This registration screen I have to put a message if the user clicks a tab, "you lost data"
    I tried using the function OnClientTabSelecting
    But I have to make sure that the User is in the registration screen, and not in default.aps
    I tried to use session to store the value, but I noticed that javascript does not work
    Would any idea to help me
