c# - UWP, Content Dialog for Login -

how use content dialog simple login screen. when try use this:

contentdialog d = new contentdialog();         d.content = contentgrid;         d.primarybuttontext = "aaa";         d.primarybuttonclick += async delegate         {          }; await dlg.showasync(); 

on button click can run logic, hide entiredialog. want show processing animation, , show "check" results. possible?

yeah, possible. key point here using contentdialogbuttonclickeventargs.getdeferral method contentdialogbuttonclickdeferral before performe async operations , complete deferral when async operation complete. example:

contentdialog contentdialog = new contentdialog(); contentdialog.content = "login test"; contentdialog.primarybuttontext = "login"; contentdialog.primarybuttonclick += async (s, args) => {     contentdialogbuttonclickdeferral deferral = args.getdeferral();      //do async sign in operation     await task.delay(3000);  //here wait 3 seconds      deferral.complete(); }; await contentdialog.showasync(); 

and there example shows how create , use custom dialog (signincontentdialog) derived contentdialog under examples section in contentdialog class. can have check.
