Querystring -> Codebehind?

<i><b>Originally posted by : Bret (bret.vanhorn@tripleteam.com)</b></i><br />Okay, this is probably a silly question, but I'm new to .NET/VB and haven't been able to find an answer to this anywhere. <br /><br />I want to send a variable from an ASPX page querystring/GET form submission and have the codebehind for that page access that variable on postback, preferably without a server control. <br /><br />Classic ASP has that handy request.querystring("foo") method of accessing such variables, but I can't see a way to access that from the codebehind, even if I update the syntax to request.querystring("foo")(0).<br /><br />If anyone has any ideas, I'd gladly give you millions of dollars to ease my suffering mind -- only I don't have a million dollars. So my undying gratitude will have to suffice.<br /><br />Thanks in advance,<br /><br />-Bret<br /><br />
