範例

下列範例將示範如何覆寫 Verbs 屬性，以便插入 ActivityPreviewDesigner 的自訂動詞動作。 CreateActivityVerbs 會建立名稱為 ActivityDesignerVerb 的新 "Add New Parallel Branch"，並與名稱為 OnAddParallelBranch 的事件處理常式產生關聯。 在工作流程設計工具中按一下此動詞時，會呼叫事件處理常式。

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
