Throw Activity Designer

The Throw activity designer is used to create and configure a Throw activity.

The Throw Activity

The Throw activity throws an exception.

Using the Throw Activity Designer

Access the Throw activity designer in the Error Handling category of the Toolbox.

The Throw 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. This creates a Throw activity with a default DisplayName of Throw. The DisplayName value can be edited in the header of the Throw activity designer or in the DisplayName box of the property grid. The Exception property must be edited on the property grid.

The Throw Properties

The following table shows the Throw properties and describes how they are used in the designer.

Property Name	Required	Usage
DisplayName	False	Specifies the optional friendly name of the Throw activity. The default is Throw.
Exception	True	The exception to throw. This exception must derive from Exception. To specify the exception, type a Visual Basic expression in the property grid.
