ValueTuple With WPF Binding [duplicate]

Question

why binding to ValueTuple property members (like Item1, Item2 ect) dont work?

<TextBlock x:Name="txtTest" Text="{Binding Item1}" />

the code:

txtTest.DataContext = ("Item A", "Another Item..");

output window:

BindingExpression path error: 'Item1' property not found on 'object' ''ValueTuple`2'

However in Tuple It always worked.

Schalles

this.DataContext = new Tuple<string, string>("item 1", "item 2"); this is working fine. – Highflier

@Highflier Right. I already mentioned this in my question. – Schalles

Answer 1

As stated in the documentation, Item1 and Item2 of a ValueTuple are fields rather than properties and you can only bind to public properties in WPF.

So if you want to be able to bind to a tuple, you should use the Tuple class.
