WinRT - XAML binding DataContext

Question

I tried to bind ObservableCollection<UserProfile> UsersList to pages DataContext, but program keeps telling me, that he cannot find UsersList although I can see it's values in OutPut using Debug.WriteLine. But on the other hand, if I add DataContext in C# code, everything works perfectly. What am I doing wrong?

C# code:

this.DataContext = new UsersViewModel(); //inside MainPage constructor

XAML code:

DataContext="{Binding UsersViewModel, RelativeSource={RelativeSource Self}}" //inside <page .../>

Answer 1

try to set binding this way instead :

DataContext="{Binding RelativeSource={RelativeSource Self}}"

Your current binding means, bind data context to a property named UsersViewModel declared in it self. That will work if, for example, you have something like this in code behind :

public UsersViewModel UsersViewModel { get; set; }

then DataContext will be set to that property.

UPDATE :

Looking at your answer, you can try do it this way to set DataContext in Page level :

<Page.DataContext>
    <local:UsersViewModel />
</Page.DataContext>
