Created Bindable WindowsFormsHost, but child update is not being reflected to control

Question

I created ran into a problem where i want to bind a control to a windowsFormsHost control. But as we all know, the Child property is not a DP, so i created a wrapper. ``` ///

/// Bindable version of windows form hosts ///

public class BindableWindowsFormsHost : WindowsFormsHost { ///

/// Max value of the textbox ///

public Control BindableChild { get { return (Control)GetValue(BindableChildProperty); } set { SetValue(BindableChildProperty, value); } } // Using a DependencyProperty as the backing store for Max. This enables animation, styling, binding, etc... public static readonly DependencyProperty BindableChildProperty = DependencyProperty.Register("BindableChild", typeof(Control), typeof(BindableWindowsFormsHost), new FrameworkPropertyMetadata(new PropertyChangedCallback(OnBindableChildChanged))); ///

Accepted Answer

Instead of creating a wrapper you could wrap the WindowsFormsHost in a ContentControl and set its Content property via a binding. That way you avoid the issue with the WindowsFormsHosts Child property not being a dependency property.

Something like this in XAML:

```
<ContentControl Content="{Binding MyWindowsFormsHost}" />
```

..and this in your code-behind:

```
public WindowsFormsHost MyWindowsFormsHost
{   
    get { return new WindowsFormsHost(){Child=myWinformsControl}; }   
}
```
