Set equivalent of {Binding .} from code behind in Xamain?

Question

I am currently setting a label binding from code behind which works fine as below:

lblLabel.SetBinding(Label.TextProperty, model.DataField);

However I now need to add multiple bindings (model.Title and model.DataField) to the Label so want to bind the entire BindingContext to use in a converter, in XAML I would use:

{Binding .}

So have tried the following from the code behind but this just passes null to the converter?

lblLabel.SetBinding(Label.TextProperty, ".", BindingMode.Default, new ModelToStringConverter());

Is this possible to achieve from the code behind or can you only use "." in XAML directly?

Answer 1

The equivalent to XAML's "." is this .

For your scenario, you need the path as a string tho, so you can use "." by creating a new Binding :

ModelToStringConverter modelToStringConverter = new ModelToStringConverter();
txtBlock.SetBinding(TextBlock.TextProperty, new Binding(".", converter: modelToStringConverter);
