I am used to VB.Net, and I recently starting using ASP.Net 2.0 with VB.Net. What I do not understand is how to keep my variables. Everytime the page goes back to the server I lose information. It gets lost. I've looked everywhere and read a lot of information and I am just not understanding what to do to keep my variables. For example I am trying to do a calculation in ASP.Net. I put a number in a textbox. Then I press a button and try to enter the next number, but the first number is gone. I've read about Session variables and such, but I do not understand how to use them or where to put them in the code. Can someone please explain to me how to keep variables and maybe give an example?
