Fields
| ValidationErrorListPropertyName |
The name for an activity constraint property that is a list of workflow run-time validation errors. |
Properties
| CacheId |
Gets the identifier of the cache that is unique within the scope of the workflow definition. (Inherited from Activity) |
| CanInduceIdle |
Gets or sets a value that indicates whether the activity can cause the workflow to become idle. (Inherited from NativeActivity) |
| Constraints |
Gets a collection of Constraint activities that can be configured to provide validation for the Activity. (Inherited from Activity) |
| DisplayName |
Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking. (Inherited from Activity) |
| Id |
Gets an identifier that is unique in the scope of the workflow definition. (Inherited from Activity) |
| Implementation |
The execution logic of the activity. (Inherited from NativeActivity) |
| ImplementationVersion |
Gets or sets the implementation version of the activity. (Inherited from NativeActivity) |
Methods
| Abort(NativeActivityAbortContext) |
When implemented in a derived class, takes actions in response to the activity being aborted. (Inherited from NativeActivity) |
| AddValidationError(NativeActivityContext, ValidationError) |
Adds a validation error to a list of run-time validation errors that are attached to the execution context. |
| CacheMetadata(ActivityMetadata) |
Not implemented. Use the CacheMetadata(NativeActivityMetadata) method instead. (Inherited from NativeActivity) |
| CacheMetadata(NativeActivityMetadata) |
Creates a NativeActivityMetadata object that contains runtime arguments for the workflow validation process. |
| Cancel(NativeActivityContext) |
When implemented in a derived class, runs logic to cause graceful early completion of the activity. (Inherited from NativeActivity) |
| Equals(Object) |
Determines whether the specified object is equal to the current object. (Inherited from Object) |
| Execute(NativeActivityContext) |
Invokes the process that validates an activity. |
| 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) |
| OnCreateDynamicUpdateMap(NativeActivityUpdateMapMetadata, Activity) |
Raises an event when creating a map for the dynamic update. (Inherited from NativeActivity) |
| OnCreateDynamicUpdateMap(UpdateMapMetadata, Activity) |
Raises an event when creating a map for the dynamic update. (Inherited from NativeActivity) |
| OnExecute(NativeActivityContext, Object, ValidationContext) |
When implemented by a derived class, validates the specified object using the specified native activity and validation contexts. |
| ShouldSerializeDisplayName() |
Indicates whether the DisplayName property should be serialized. (Inherited from Activity) |
| ToString() |
Returns a String that contains the Id and DisplayName of the Activity. (Inherited from Activity) |
| UpdateInstance(NativeActivityUpdateContext) |
Updates the instance of NativeActivity. (Inherited from NativeActivity) |
