I get a specified cast not valid error when I trie to move between pages in asp.net. It doesn´t give any row that produces the error and I can´t run any pages that are written in asp.net. It doesn´t matter how simple the page is, the simplest page only contains one button to go to page number 2, even that doesn´t work. It used to work but all of a sudden it didn´t, so the pages themselfes shouldn´t really cause the error. <BR>I think there are some settings that I don´t know of that need some fix. <BR><BR>I have changed settings in machine.config but that´s all, the client has also changed some user-domain settings, any ideas? Because I ran out of them.
