Issues with Binding Custom Control Properties in WPF - Unexpected DataContext Behavior
I'm stuck trying to I'm learning this framework and I'm having trouble with I'm relatively new to this, so bear with me... I'm working on a WPF application and I've created a custom control that implements a few dependency properties. Everything seems to work fine until I try to bind the control's properties to the view model. I notice that when I set the DataContext of the parent window, the properties I expected to bind are not populating correctly. Instead, they're either defaulting to null or not updating at all. Here’s an example of the custom control I created: ```csharp public class MyCustomControl : Control { public static readonly DependencyProperty MyPropertyProperty = DependencyProperty.Register( "MyProperty", typeof(string), typeof(MyCustomControl), new PropertyMetadata(default(string))); public string MyProperty { get { return (string)GetValue(MyPropertyProperty); } set { SetValue(MyPropertyProperty, value); } } static MyCustomControl() { DefaultStyleKeyProperty.OverrideMetadata(typeof(MyCustomControl), new FrameworkPropertyMetadata(typeof(MyCustomControl))); } } ``` In my XAML file, I'm using the control like this: ```xml <local:MyCustomControl MyProperty="{Binding Path=SomeViewModelProperty}" /> ``` I also set the DataContext in the code-behind of my window: ```csharp public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); DataContext = new MyViewModel(); } } ``` The issue I'm facing is that `SomeViewModelProperty` is always null when I check it from within the custom control. I've tried implementing `INotifyPropertyChanged` in my view model and ensuring that the property raises `PropertyChanged` notifications, but that doesn't seem to help. Has anyone encountered this issue before? What am I missing in terms of binding the properties correctly? Any insight into how to troubleshoot this would be greatly appreciated! The stack includes C# and several other technologies. Any ideas how to fix this? This is for a desktop app running on macOS. Cheers for any assistance!
