binding code in cpp.
{
Binding biding2;
dynamic2 = winrt::make<implementation::Dynamic>(L"100");
biding2.Converter(dynamic2);
biding2.Mode(Data::BindingMode::TwoWay);
biding2.UpdateSourceTrigger(Data::UpdateSourceTrigger::PropertyChanged);
biding2.Source(dynamic2);
biding2.Path(PropertyPath(L"Value"));
Hd().SetBinding(Hd().TextProperty(), biding2);
}
idl defined in used component.
import "Dynamic.idl";
namespace App1
{
[default_interface]
runtimeclass MainWindow : Microsoft.UI.Xaml.Window
{
MainWindow();
//Dynamic MyProperty;
}
}
if I add Dynamic property in MainWindow idl file , this works fine. otherwise if I comment Dynamic property, the binding will don't work. maybe biding2.Path(PropertyPath(L"Value")); has inernal bug. and if i remove binding path set, it's also works fine.
