c# - Unable to navigate to another page on button click in windows phone 8.1 -

-

i have button & upon clicking it, need go xaml page.

this button resides in page1.xaml

<button content="button name" horizontalalignment="center" verticalalignment="center" click="button_click" foreground="#ff119ff0"/>       private void button_click(object sender, routedeventargs e)     {        framebody.navigate(typeof(homepage));      }

but not able navigate homepage.xaml.

what can reason??

these libraries included:

using system; using system.collections.generic; using system.io; using system.linq; using system.runtime.interopservices.windowsruntime; using windows.foundation; using windows.foundation.collections; using windows.ui.xaml; using windows.ui.xaml.controls; using windows.ui.xaml.controls.primitives; using windows.ui.xaml.data; using windows.ui.xaml.input; using windows.ui.xaml.media; using windows.ui.xaml.navigation;

the function button_click() defined in page1.xaml.cs.

this code use in project:

    private void itemview_itemclick(object sender, itemclickeventargs e)     {         var albumid = ((album)e.clickeditem).id;         if (!frame.navigate(typeof(albumpage), albumid))         {             var resourceloader = resourceloader.getforcurrentview("resources");             throw new exception(resourceloader.getstring("navigationfailedexceptionmessage"));         }     }

the part focus on frame.navigate(typeof(albumpage)).

i want pass information page, that's why pass albumid.

if want retrieve passed argument in other page, might want use code:

    private void navigationhelper_loadstate(object sender, loadstateeventargs e)     {         var albumid = (int)e.navigationparameter;     }
