GetErrors()()()() |
Returns a collection of object-level errors.
(Inherited from AbstractModelBase.) |

(Inherited from AbstractModelBase<(Of <(<'TPropertyTracking>)>)>.) |
|
|
GetNew<(Of <<'(T>)>>)(String) |
Fetches a value, creating it if it doesn't exist.
(Inherited from AbstractModelBase<(Of <(<'TPropertyTracking>)>)>.) |

|
|
OnValidateObject |
Override this method to add imperative validation at the object level.
(Inherited from AbstractModelBase.) |
|
|
OnValidateProperty |
Override this method to add imperative validation at the property level.
(Inherited from AbstractModelBase.) |
|
|
RejectChanges |
Discards all pending changes and reverts to the values used the last time AcceptChanges was called.
|
|
|
RemoveHandler |
Removes a weak event handler.
(Inherited from AbstractModelBase.) |
|
|
Set(Nullable<(Of <<'(Object>)>>), String) |
Set the indicated property to the value.
If the value doesn't match the previous value, or if there is no previous value, raise a property changed notification.
(Inherited from AbstractModelBase<(Of <(<'TPropertyTracking>)>)>.) |
|
|
Set<(Of <<'(T>)>>)(T, PropertyChangedEventHandler, String) |
Set the indicated property to the value.
If the value doesn't match the previous value, or if there is no previous value, raise a property changed notification.
(Inherited from AbstractModelBase<(Of <(<'TPropertyTracking>)>)>.) |
|
|
Set<(Of <<'(T>)>>)(T, ValueChanged<(Of <<'(T>)>>), String) |
Set the indicated property to the value.
If the value doesn't match the previous value, or if there is no previous value, raise a property changed notification.
(Inherited from AbstractModelBase<(Of <(<'TPropertyTracking>)>)>.) |
|
|
Set<(Of <<'(T>)>>)(T, NotifyCollectionChangedEventHandler, String) |
Set the indicated property to the value.
If the value doesn't match the previous value, or if there is no previous value, raise a property changed notification.
(Inherited from AbstractModelBase<(Of <(<'TPropertyTracking>)>)>.) |

|
ToString | (Inherited from Object.) |

Properties
| Name | Description | |
|---|---|---|
|
HasErrors |
Returns True if there are any errors.
(Inherited from AbstractModelBase.) |
|
|

Returns True if any fields were modified since the last call to AcceptChanges. This does walks the object graph for changes in child objects as well.
|
|
|
IsChangedLocal |
Returns True if any fields were modified since the last call to AcceptChanges. This does not walk the object graph.
|
