Button click event

I have a procedure that is called when I click on a button. The result of the procedure is to generate an XmlElement, and from the procedure I want to pass the values of each "name" element within the XmlElement to a new page. This new page will display a list of products, which will be retrieved by looking up from a database the list submitted from the previous page. I just cannot figure out how to do this. In ASP I used forms and the "get" method, I cannot figure out despite Google searches how this is done in ASP.net (vb).
Any links or just an explanation of briefly how to do this would be appreciated. Thanks
