Question : Why can't I insert a break point in asp.net backend code?

Hi, I'm using
VS2008, .net 3.5 and C#.  There are line numbers for each LOC.  How can I turn off the option that displays the line number?  Also, why can't I click to the left of the line of code to get a break point like I've done in asp.net mvc?  I tried the Debug menu and there is only option to insert break point to break at function.
Thanks,.

press F9
line numbers are good ;) if you want to turn it off, go to options, advanced, editors, all languages, turn off line numbers
