Hi, In your viewmodel of the view that contains the frame, create a property to keep the page to navigate like,
private Page _PageToNavigate;
public Page PageToNavigate
{
get { return _PageToNavigate; }
set { _PageToNavigate = value; OnPropertyChanged("PageToNavigate"); }
}
And bind this property to Frame's Content property in your view like,
<frame x:name="Browser" content="{Binding PageToNavigate}" xmlns:x="#unknown" />
Now, you just need to assign the page which you want to navigate to the
PageToNavigate property. It has
OnPropertyChanged defined, so wherever this property is used, everywhere it gets updated with the currently assigned value (i.e., page).
