mvvm - How to insert button into Grid from ViewModel C# class in windows 8.1 store app -

-

i can insert button grid control code behind file 

var felem = new button();                   felem.content = "button text"; bggrid.children.add(felem); // bggrid defined in xaml

how can add same button grid view model class?

in code-behind of xaml page (xaml.cs) need publicly expose grid

public grid mygrid => bggrid;

then can access viewmodel so:

frame rootframe = window.current.content frame; var page = rootframe.content yourpageclassname; var felem = new button();                  felem.content = "button text"; page.mygrid.children.add(felem);

however, not mvvm @ all.
