Properties

BindingGroup	Gets the BindingGroup that this binding expression belongs to.
HasError	Gets a value that indicates whether the parent binding has a failed validation rule.
HasValidationError	Gets a value that indicates whether the parent binding has a failed validation rule.
IsDirty	Gets or sets a value that indicates whether the target of the binding has a value that has not been written to the source.
ParentBindingBase	Gets the BindingBase object from which this BindingExpressionBase object is created.
Status	Gets the status of the binding expression.
Target	Gets the element that is the binding target object of this binding expression.
TargetProperty	Gets the binding target property of this binding expression.
ValidationError	Gets the ValidationError that caused this instance of BindingExpressionBase to be invalid.

Methods

Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode()	Serves as the default hash function. (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 in TwoWay or OneWayToSource bindings.
UpdateTarget()	Forces a data transfer from the binding source to the binding target.
ValidateWithoutUpdate()	Runs any ValidationRule objects on the associated Binding that have the ValidationStep property set to RawProposedValue or ConvertedProposedValue. This method does not update the source.
