自定义控件中的控件调用引用控件的页面里的函数

Imports System.ComponentModelImports System.Web.UINamespace WebControls <DefaultProperty("Text"), ToolboxData("<{0}: CustomToolBar runat=server></{0}:CustomToolBar>")> Public Class CustomToolBar Inherits System.Web.UI.WebControls.WebControl'定义3按钮 Public WithEvents btnAdd As System.Web.UI.WebControls.Button Public WithEvents btnDelete As System.Web.UI.WebControls.Button Public WithEvents btnEdit As System.Web.UI.WebControls.Button Private Sub Button_Ini(ByRef objButton As Button, ByVal Text As String)objButton = New System.Web.UI.WebControls.ButtonobjButton.Text = Text Me.Controls.Add(objButton)End Sub Public Sub New() Button_Ini(btnAddNew, "新增") Button_Ini(btnDeleteData, "删除")End Sub End ClassEnd Namespace/////////////////////////////////////为了简明，没在控件里加什么事件、方法、属性之类的。把它编译成dll调用方法：新建一页面test.aspx，把控件添加进去。控件Id为CustomToolBar。在test.aspx.vb里的 Page_Init过程里添加：Public Class frmFabricItem Inherits System.Web.UI.Page Protected DbaControls As AMMS.DbaControls#Region " Web 窗体设计器生成的代码 " '该调用是 Web 窗体设计器所必需的。 <System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent() End Sub Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init 'CODEGEN: 此方法调用是 Web 窗体设计器所必需的 '不要使用代码编辑器修改它。 InitializeComponent() AddHandler CustomToolBar. btnAdd.Click, AddressOf Me.btnAdd_Click AddHandler CustomToolBar. btnDelete.Click, AddressOf Me.btnDelete_Click AddHandler CustomToolBar. btnEdit.Click, AddressOf Me.btnEdit_Click End Sub#End Region Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load '在此处放置初始化页的用户代码End Sub'定义btnAdd_Click过程Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)……..End Sub'定义btnDelete_Click过程Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)……..End Sub'定义btnAdd _Click过程Private Sub btnEdit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)……..End Sub End Class/////////////////////////////////其中关键是：AddHandler 语句。 还有要放在Page_Init过程里。附：AddHandler 语句请参见RemoveHandler 语句 | Handles | 事件和事件处理程序 | AddHandler 和 RemoveHandler 将事件与事件处理程序相关联。AddHandler event, AddressOf eventhandler各部分说明event 要处理的事件的名称。 eventhandler 将处理事件的过程的名称。 备注AddHandler 和 RemoveHandler 语句使您可以在程序执行过程中的任何时候启动和停止事件处理。
