FrameworkElement.GetBindingExpression(DependencyProperty) Method

Definition

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

public:
 System::Windows::Data::BindingExpression ^ GetBindingExpression(System::Windows::DependencyProperty ^ dp);
public System.Windows.Data.BindingExpression GetBindingExpression (System.Windows.DependencyProperty dp);
member this.GetBindingExpression : System.Windows.DependencyProperty -> System.Windows.Data.BindingExpression
Public Function GetBindingExpression (dp As DependencyProperty) As BindingExpression

Parameters

dp
DependencyProperty

The target DependencyProperty to get the binding from.

Returns

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

Remarks

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.
