How to: Get the Binding Object from a Bound Target Property
This example shows how to obtain the binding object from a data-bound target property.
Example
You can do the following to get the Binding object:
// textBox3 is an instance of a TextBox
// the TextProperty is the data-bound dependency property
Binding myBinding = BindingOperations.GetBinding(textBox3, TextBox.TextProperty);

You must specify the dependency property for the binding you want because it is possible that more than one property of the target object is using data binding. |
Alternatively, you can get the BindingExpression and then get the value of the ParentBinding property.
For the complete example see Binding Validation Sample.
| Note: |
|---|
If your binding is a MultiBinding, use BindingOperations.GetMultiBinding. If it is a PriorityBinding, use BindingOperations.GetPriorityBinding. If you are uncertain whether the target property is bound using a Binding, a MultiBinding, or a PriorityBinding, you can use BindingOperations.GetBindingBase. |
