Implement ChoicesBindingNameProperty

[maurice0800]

🚀 Feature Requests

ChoicesBindingNameProperty is currently commented out in the code. You cannot set it but there already is an implementation for it.

Contextualize the feature

You can set any object as Choices but currently there is no option to specify which property of the object should be shown in the picker dialog.

Describe the feature

There should be an option to specify a converter which receives the object from the list and returns a string for the dialog. For this the type of ChoicesBindingName needs to be changed to BindingBase.

Usage would be something like this:

<ui:MaterialTextField AlwaysShowUnderline="True"
                                Choices="{Binding Choices}"
                                ChoicesBindingName="{Binding Converter={StaticResource ChoicesToStringConverter}}"
                                InputType="Choice"
                                Placeholder="Demo"
                                ReturnType="Next"/>
