i place box in centre of screen in xaml grid layout. however, able use grid place objects inside box also. see below. how this? if red box span 5 rows, of different height, row above , below must same height. there similar arrangement columns. must responsive, such code works on wide range of device sizes. using xamarin. i don't know if xamarin introduces different behavior, vanilla xaml, should able set verticalalignment , horizontalalignment center , box should centered (you need provide explizit size or put box). if want layout content in box, should define separate gridlayout inside box (maybe taking @ sharedsizegroup if need share sizes between 2 grids).
