WPF. Find control that binds to specific property

Question

Any ideas on how to implement a method that given a propertyname, finds a control (perhaps from a visualtree) which is bound to the given property?

Try this one. First, copy-paste this DependencyObjectHelper class in your project. It has a function that allows you to get all the BindingObjects in a given object.

public static class DependencyObjectHelper
{
    public static List GetBindingObjects(Object element)
    {
        List bindings = new List();
        List dpList = new List();
        dpList.AddRange(DependencyObjectHelper.GetDependencyProperties(element));
        dpList.AddRange(DependencyObjectHelper.GetAttachedProperties(element));

        foreach (DependencyProperty dp in dpList)
        {
            BindingBase b = BindingOperations.GetBindingBase(element as DependencyObject, dp);
            if (b != null)
            {
                bindings.Add(b);
            }
        }

        return bindings;
    }

    public static List GetDependencyProperties(Object element)
    {
        List properties = new List();
        MarkupObject markupObject = MarkupWriter.GetMarkupObjectFor(element);
        if (markupObject != null)
        {
            foreach (MarkupProperty mp in markupObject.Properties)
            {
                if (mp.DependencyProperty != null)
                {
                    properties.Add(mp.DependencyProperty);
                }
            }
        }

        return properties;
    }

    public static List GetAttachedProperties(Object element)
    {
        List attachedProperties = new List();
        MarkupObject markupObject = MarkupWriter.GetMarkupObjectFor(element);
        if (markupObject != null)
        {
            foreach (MarkupProperty mp in markupObject.Properties)
            {
                if (mp.IsAttached)
                {
                    attachedProperties.Add(mp.DependencyProperty);
                }
            }
        }

        return attachedProperties;
    }
}

Then, create this GetBindingSourcesRecursive function. It recursively collects the DependencyObjects in the visual tree that has at least one Binding object targetting a given property name.

private void GetBindingSourcesRecursive(string propertyName, DependencyObject root, List
