Add text to bound values in Xamarin.forms - binding

Question

My modelView:
public string Status {
get { return _status; }
set {
if (value == _status) {
return;
}
_status = value;
OnPropertyChanged ("Status");
}
My View:
Label labelStatus = new Label {
TextColor = Color.Green,
FontSize = 20d
};
labelStatus.SetBinding (Label.TextProperty, "Status");
Then I want to present the status using something like:
string presentStatus = string.Format("Your status is {0}...", labelStatus);
Label yourStatus = new Label{Text=presentStatus}
But that doesn't really work. Nor does using
string presentStatus = string.Format("Your status is {0}...", SetBinding(Label.TextProperty,"Status"));
So how should I do to add my bound values with more text before presenting them for the user in a view.
If using XAML (which i don't), it seems possible according to: http://developer.xamarin.com/guides/cross-platform/xamarin-forms/xaml-for-xamarin-forms/data_binding_basics/

Answer 1

Xamarin Forms binding implementation doesn't currently allow complex binding scenarios like embedding bound text within static text.
There are two options
a. use multiple labels - one with the static text, one with the bound text
b. use a property on your ViewModel that concatenates the text for you
public string StatusText
{
get
{
return string.Format("Your status is {0}...", Status);
}
}
public string Status {
get { return _status; }
set {
if (value == _status) {
return;
}
_status = value;
OnPropertyChanged ("Status");
OnPropertyChanged ("StatusText");
}

You can do that in the BindingContextChanged-event:
labelStatus.BindingContextChanged += (sender, e) =>
{
// Here you can change the Text dynamically
// E.G. labelStatus.text = "Title: " + labelStatus.text
};
