Examples

The following example demonstrates how to override the Verbs property to insert custom verb actions for a ActivityPreviewDesigner. The CreateActivityVerbs creates a new ActivityDesignerVerb named "Add New Parallel Branch" and associates an event handler named OnAddParallelBranch. When the verb is clicked in the workflow designer, the event handler is called.

private ActivityDesignerVerbCollection verbs = null;

protected override ActivityDesignerVerbCollection Verbs
{
    get
    {
        if (this.verbs == null)
            CreateActivityVerbs();

        return this.verbs;
    }
}

private void CreateActivityVerbs()
{
    this.verbs = new ActivityDesignerVerbCollection();

    ActivityDesignerVerb addBranchVerb = new ActivityDesignerVerb(this,
        DesignerVerbGroup.View, "Add New Parallel Branch", new EventHandler(OnAddParallelBranch));
    this.verbs.Clear();

    this.verbs.Add(addBranchVerb);
}

protected void OnAddParallelBranch(object sender, EventArgs e)
{
    // Code for adding a new branch to the parallel activity goes here
}

Private verbsValue As ActivityDesignerVerbCollection = Nothing

Protected Overrides ReadOnly Property Verbs() As ActivityDesignerVerbCollection
    Get
        If verbsValue Is Nothing Then
            CreateActivityVerbs()
        End If
        Return Me.verbsValue

    End Get
End Property

Private Sub CreateActivityVerbs()
    Me.verbsValue = New ActivityDesignerVerbCollection()

    Dim addBranchVerb As New ActivityDesignerVerb(Me, DesignerVerbGroup.View, "Add New Parallel Branch", AddressOf OnAddParallelBranch)

    Me.verbsValue.Clear()

    Me.verbsValue.Add(addBranchVerb)
End Sub

Protected Sub OnAddParallelBranch(ByVal sender As Object, ByVal e As EventArgs)
    ' Code for adding a new branch to the parallel activity goes here
End Sub
