Returns the BindingExpression that represents the binding on the specified property.
Assembly: PresentationFramework (in PresentationFramework.dll)
Checking the return value for nullptr is a technique you can use to determine whether a property has an active binding.
This method is really just a convenience wrapper around the BindingOperations::GetBindingExpression method. passes the current instance and the dp parameter to BindingOperations::GetBindingExpression.
This example shows how to obtain the binding object from a data-bound target property.
You can do the following to get the Binding object:
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.
For the complete example see Binding Validation Sample.
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.
