The BindingExpression type exposes the following members.
| Name | Description | |
|---|---|---|
 | DataItem | Gets the binding source object that this BindingExpression uses. |
| ParentBinding | Returns the Binding object of the current BindingExpression. |
| Name | Description | |
|---|---|---|
 | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| UpdateSource | Sends the current binding target value to the binding source property in TwoWay bindings. |
A Binding object can be used by multiple binding targets. The BindingExpression class, however, represents a single binding. You can retrieve a BindingExpression instance from a binding target by calling its FrameworkElement::GetBindingExpression method. You can then use the BindingExpression to call the UpdateSource method. This is useful to control when values are copied from the binding target to the binding source.
