'用途
Dim instance As WebPart

instance.CreateWebPartMenu()

public virtual void CreateWebPartMenu()

備註

繼承的System.Web.UI.Control.Load事件之後發生，據此通知網頁組件，以設定WebPartMenu屬性，會呼叫CreateWebPartMenu方法。

Examples

下列程式碼範例會顯示將上層功能表項目和兩個功能表項目新增至預設網頁組件功能表覆寫的CreateWebPartMenu方法。它假設此方法包含兩個自訂的布林值屬性、 ParentItemIsVisible和EnableItem1，可讓您控制這些功能表項目時是可見並已啟用WebPart類別的一部分。您也應該建立名為EventHandlerForItem1事件處理常式。

Public Overrides Sub CreateWebPartMenu()
    ' Declare variables for menu items.
    Dim ParentItem As MenuItem
    Dim Item1 As MenuItem
    Dim Item2 As MenuItem

    ' Create three menu items:
    ' One parent item, and two submenu items.
    ' Create the parent item.
    ParentItem = New MenuItem("ParentItem", "", "ParentItemID")

    ' Create a submenu item with a server event on click.
    Item1 = New MenuItem("Item1", "Item1ID", New EventHandler(AddressOf EventHandlerForItem1))

    ' Create a submenu item with a client event on click. 
    Item2 = New MenuItem("Item2", "javascript:alert('Item2 was clicked.');", "Item2ID")

    ' Add the submenu items to the parent item.
    ParentItem.MenuItems.Add(Item1)
