From: Jeff on 5 Jul 2010 14:01 Hi asp.net 4.0 vs2010 I'm developing an asp.net model -view-presenter, and to my surprise i see that when I click on the linkbutton in the window the Page_Load event is fired again. Is that normal? I'm used to webforms where we could just do a if (!Page.IsPostBack) if statement in the Page_Load. I did that but then no action happend when I clicked the linkbuttons in the window. any suggestions?

And how you would get a string value from a Querystring to the MVP is you would have a string property on the View Interface. On a page event such as Page_Load, you would set the string property on the View Interface with the Querystring value. Then when the application access a method in the MVP, then you can get the value for the string property on the View Interface.
From: Jeff on 5 Jul 2010 15:03 with string property on the view interface I assume you mean something like: public QueryString{ get; set;} right?
