2 years ago Two possible workarounds here:
- Make a converter that does not use the
typeparameter (make one converter per enum in the sample) - Use the
BindBackfeature and invoke a conversion method
Note for contributors
This binding engine is not providing the target type properly because of the x:Bind. The BindingExpression._bindingPath.ValueType field is empty, because x:Bind expressions don't have a path defined.
Fixing this requires to invoke the converted in the generated code, in place of the current conversion: https://github.com/unoplatform/uno/blob/b5971df6df15057d2e3e8da4bf89f391c5dfa03c/src/SourceGenerators/Uno.UI.SourceGenerators/XamlGenerator/XamlFileGenerator.cs#L3927.
Note that converter parameter would also need to be handled properly here.
Current behavior
Using a TwoWay x:Bind on SelectedIndex does not update the target with the new index.
Expected behavior
The target of the bind gets updated.
How to reproduce it (as minimally and precisely as possible)
ComboBoxSelectedIndex.zip
Run the wasm project and notice both the bind with a converter and without fails to update the target value.
