The Rethrow activity designer is used to create and configure a Rethrow activity.
The Rethrow activity
The Rethrow activity throws a previously thrown exception. This activity can only be used in a Catch handler in the TryCatch activity.
Use the ReThrow Activity Designer
Access the Rethrow activity designer in the Error Handling category of the Toolbox. The Rethrow activity designer can be dragged from the Toolbox and dropped on to the Workflow Designer surface wherever activities are usually placed, such as inside a Sequence. Dropping the activity designer creates a Rethrow activity with a default DisplayName of Throw. The DisplayName value can be edited in the header of the Rethrow activity designer, or in the DisplayName box of the property grid.
The Rethrow properties
The following table shows the Rethrow properties, and describes how they're used in the designer:
| Property Name | Required | Usage |
|---|---|---|
| DisplayName | False | Specifies the optional friendly name of the Rethrow activity. The default is Rethrow. |
