public class BindingNotification
Public Class BindingNotification
type BindingNotification = class end
| Inheritance | Object → BindingNotification |
Remarks
This class is very similar to BindingValue(T), but where BindingValue(T) is used by typed bindings, this class is used to hold binding and data validation errors in untyped bindings. As Avalonia moves towards using typed bindings by default we may want to remove this class.

| BindingNotification(Exception, BindingErrorType) | Initializes a new instance of the BindingNotification class. |
| BindingNotification(Exception, BindingErrorType, Object) | Initializes a new instance of the BindingNotification class. |
Properties

| ClearValue() | Removes the Value and makes HasValue return null. |

| ExtractValue(Object) | Gets a value from an object that may be a BindingNotification. |
| Finalize() | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (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) |
| SetValue(Object) | Sets the Value. |
| ToString() | Returns a string that represents the current object. (Overrides Object.ToString()) |
| UpdateValue(Object, Object) | Updates the value of an object that may be a BindingNotification. |
Operators
| Equality(BindingNotification, BindingNotification) | Compares two instances of BindingNotification for equality. |
| Inequality(BindingNotification, BindingNotification) | Compares two instances of BindingNotification for inequality. |
Fields
