Thanks for looking at this Paul, I have all this wiring in place, but I must be missing something else.
I have a property on my model
public string ScreenInfo
which I have wired into my view via a textbox with
I see the xxxxx value in the design view, but when I run the app, I see the view in the region, but not the date in the text box.
In the debug window I get an error, which suggests it's looking for my property on the host page. So I'm a bit confused as to why it resolves at design time but not at runtime.
System.Windows.Data Error: BindingExpression path error: 'ScreenInfo' property not found on 'ViewModel: MainViewModel' 'Eks2.ViewModels.MainViewModel' (HashCode=24981566). BindingExpression: Path='ScreenInfo' DataItem='ViewModel: MainViewModel' (HashCode=24981566);
target element is 'System.Windows.Controls.TextBox' (Name='textBox1'); target property is 'Text' (type 'System.String')..
