How to change screen's in windows phone 7?

Problem with the UriMapper. The 开发者_如何转开发flaw is when i am navigating to my EULA page which navigates to first page which navigates to Main Page.xaml but, this navigates back to EULA.xaml, here i mapped the MainPage.xaml and toggled between EULA.xaml and MainPage.xaml. So, the problem is after EULA->firstpage->EULA but i want it like EULA->firstpage->MaiNPage. How to achive this? Regards, Panache

You have a navigation loop.

Instead of mapping MainPage with UriMapper, map a virtual page eg. MainOrFirstPage.

Are you talking about a Navigation Loop ? I have this problem with a login screen : Remove a page from Navigation Stack

If you want a way to only show your EULA page once, have a look at these questions which all cover this issue:
