FrameworkElement::GetBindingExpression Method (DependencyProperty^)


Returns the BindingExpression that represents the binding on the specified property.

Namespace:   System.Windows
Assembly:  PresentationFramework (in PresentationFramework.dll)

BindingExpression^ GetBindingExpression(
	DependencyProperty^ dp


Type: System.Windows::DependencyProperty^

The target DependencyProperty to get the binding from.

Return Value

Type: System.Windows.Data::BindingExpression^

A BindingExpression if the target property has an active binding; otherwise, returns null.

Checking the return value for null 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. GetBindingExpression passes the current instance and the dp parameter to BindingOperations::GetBindingExpression.
