Question

我从动态加载的ascx控件（katalogbooklist.ascx）到它的父控件（ViewAJBarnboksKatalog.ascx）的起泡事件有问题当事件addMultiVotes_command在chiled控件中触发时，我需要在父控件中触发/运行sub uppdateraAndraModuler。
是否有人知道或知道如何做到这一点？

（代码存在于dotnetnuke cms模块中，如果有任何帮助的话）

Partial Class ViewAJBarnboksKatalog  '<--------Partial codebehind file for ViewAJBarnboksKatalog.ascx
    Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
         .. code for adding for loading katalogbooklist.ascx dynamic...
         Me.Controls.Add(..code.. add katalogbooklist.ascx ..) '
    End Sub

    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim t As Execkoden = New Execkoden()
        AddHandler t.onAjeventtest, AddressOf Uppdateramod          
    End Sub

    Public Sub Uppdateramod(sender As Object, e As ajeventArgs)
        uppdateraAndraModuler()
    End Sub

    Public Sub uppdateraAndraModuler()
           '..do some code
    End Sub
End Class     

Partial Class katalogenBookList  '<--------Partial codebehind file for katalogbooklist.ascx
    Protected Sub addMultiVotes_command(ByVal sender As Object, ByVal e As System.EventArgs)
      '..more code...
      Dim te As New Execkoden ' <----- i want to use the constructor to raise the event in class Execkoden can´t raiseevent directly it wont´t fire
       '... more code...
    End sub
End Class


Public Class ajeventArgs : Inherits EventArgs        
    Public Sub New()
    End Sub
End Class

Public Delegate Sub Uppdatera(sender As Object, e As ajeventArgs)

Public Class Execkoden
    Public Event onAjeventtest As Uppdatera
    Public Sub New()
        RaiseEvent onAjeventtest(Me, New ajeventArgs)
    End Sub
End Class

Answer 1

在子控件中创建一个事件处理程序，如下所示：

public event EventHandler DeleteButtonClick;

在子控件中单击按钮时，请执行以下操作：

protected void DeleteClick(object sender, EventArgs e)
{
    if (this.DeleteButtonClick != null)
        this.DeleteButtonClick(sender, e);
}

在父控件中，在标记中：

<UC:SomeUserControl ID="UserControl1" runat="server" OnDeleteButtonClick="UserControl1_DeleteClick" ...>

在父控件后面的代码中：

protected void UserControl1_DeleteClick(object sender, EventArgs e)
{
    //do something
}

我建议使用内置于DotNetNuke的IMC或Inter Module Communication功能。

从用户控件上升事件或在用户控件之间进行通信
