public sealed partial class ThrowWorkflow : SequentialWorkflowActivity
{
    [System.Diagnostics.DebuggerNonUserCode()]
    private void InitializeComponent()
    {
        this.CanModifyActivities = true;
        System.Workflow.ComponentModel.ActivityBind activitybind1 = new System.Workflow.ComponentModel.ActivityBind();
        this.throwActivity1 = new System.Workflow.ComponentModel.ThrowActivity();
        activitybind1.Name = "ThrowWorkflow";
        activitybind1.Path = "ThrownException";
        //
        // throwActivity1
        //
        this.throwActivity1.Name = "throwActivity1";
        this.throwActivity1.SetBinding(System.Workflow.ComponentModel.ThrowActivity.FaultProperty, ((System.Workflow.ComponentModel.ActivityBind)(activitybind1)));
        //
        // ThrowWorkflow
        //
        this.Activities.Add(this.throwActivity1);
        this.Name = "ThrowWorkflow";
        this.CanModifyActivities = false;
    }

    private Exception thrownExceptionValue = new System.Exception("My Exception Message.");

    public Exception ThrownException
    {
        get { return thrownExceptionValue; }
        set { thrownExceptionValue = value; }
    }

    private ThrowActivity throwActivity1;
}

    Public Property ThrownException() As Exception
        Get
            Return thrownExceptionValue
        End Get
        Set(ByVal value As Exception)
            thrownExceptionValue = value
        End Set
    End Property

    Private throwActivity1 As ThrowActivity

End Class

Remarks

If subscribed to, this event is raised every time that an instance of the child activity is created for an item in the Children collection. The Children collection is set through the ReplicatorChildEventArgs of the Initialized event handler. The child Activity instance is passed in the call so that the ReplicatorActivity can set values on the child. The relevant InstanceData object from the Children collection is also passed.
