EditableObjectPropertyBag Members

Property bag with two-level change tracking capabilities.

Marks all fields as unchanged by storing them in the original values collection.

This creates a checkpoint using the current values. The checkpoint remains available until EndEdit or CancelEdit is called.

This reverts all changes to the checkpoint values. CancelEdit is called recursively on any value in the original list.

Implementors need to override this to return the indicated value.

This removed one level of checkpoint values. EndEdit is called recursively on any value in the list of checkpoint values.

Determines whether the specified object is equal to the current object.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Fetches a value, returning Default(T) if it doesn't exist.

Fetches a value, using the default value it if it doesn't exist.

Serves as the default hash function.

Fetches a value, creating it if it doesn't exist.

Fetches a value, creating it if it doesn't exist.

Gets the previous value for the indicated property.

Gets the index of the property.

Gets the Type of the current instance.

Implementors need to override this to return the indicated value.

Determines whether any objects have unsaved changed in the graph.

This property indicates whether or not the associated property was created.

Creates a shallow copy of the current Object.

Triggers the RevalidateObject event.

Triggers the RevalidateProperty event.

Replaces the current values collection with the original values collection.

Uses the property metadata to trigger validation on all model properties. Then requests validation on the object itself.

Implementors need to override this to save the indicated value.

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.

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.

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.

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.

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.

Returns a string that represents the current object.

Updates the IsChangedLocal flag by recomparing all properties.

Returns True if any fields were modified since the last call to AcceptChanges. This does not walk the object graph.

Cached metadata for the associated model.

Access to the values dictionary for sub-classes. Extreme care must be taken when working this dictionary directly, as events will not be automatically fired.

This fires for each changed property.

Occurs just before a property value is changed.

This fires after one or more properties have been changed and their corresponding RevalidateProperty events have been handled.

This fires after one or more properties have been changed.
