How to Use a Collection in Multiple Windows

Question

I have a Public Module named "GlobalElements" that contains a Public ObservableCollection(Of Widget) named ocWidgets. I want to use ocWiddgets as a ItemsSource for ComboBoxes on multiple wpf windows. In the XAML for such a window I tried what seemed to me to be the logical code:

<Window
	    xmlns:self="clr-namespace:PIM"
		....>
	<MyComboBox
        ItemsSource="{Binding Path=self:GlobalElements.ocWidgets}"
		.... />

but that gives the error "Invalid property path syntax". Other permutations of that syntax yield the same result.

For now I just make a copy of ocWidgets in each wpf window and use that copy for the ItemsSource. But surely there is a way to just directly reference ocWidgets in the Module?

Answer 1

Try this: ItemsSource="{x:Static self:GlobalElements.ocWidgets}".
