Specifically, this provides the value of the parameter parameter of the convert or convertback methods of the specific converter that is requested with the converter property.
In this article we demonstrate how to use and write xaml behaviors in a winui 3 desktop app
We’ll cover some of the existing behaviors that are exposed via community toolkit and its sample app, and we also write a new one. Using winui3 and xaml data binding, how do you get a field to update when the source contains an indexing operation and is a subfield I have a state class named playerstate that contains many fields i want to bind via xaml, so i want a solution that scales well. To put it simply, desktopwindowxamlsource is unable to host winui 3 controls
As the documentation states, desktopwindowxamlsource is able to host any control that derives from windows.ui.xaml.uielement, and winui 3 controls do not derive from this. Gets or sets the converter object that is called by the binding engine to modify the data as it is passed between the source and target, or vice versa. The conversion function here is again very generic, matching what is done with an ivalueconverter
