How to reference a control on windows phone main page from any other non UI class? -


i thought access control on main page non ui class in same namespace using

            var frame = application.current.rootvisual phoneapplicationframe;             var startpage = frame.content phoneapplicationpage;

but intellisense doesn't show control.

didn't find on google that's weird.

if want access control class, can either:

  • use findname method retrieve it:

    var mybutton = (button)startpage.findname("mybutton");

  • expose control public property, , cast page strong type rather phoneapplicationpage:

    in manpage.xaml.cs:

    public button mybutton {         {         return this.mybutton;     } }

    in other class:

    var frame = (phoneapplicationframe)application.current.rootvisual; var startpage = (mainpage)frame.content;   // here, can use startpage.mybutton

note accessing ui control outside of page bad idea. may want re-think application's architecture rather doing (the mvvm pattern can instance).
