FrameworkElement::GetBindingExpression Method (DependencyProperty^)
.NET Framework (current version)
Returns the BindingExpression that represents the binding on the specified property.
Assembly: PresentationFramework (in PresentationFramework.dll)
Parameters
- 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.
