我有一个带有两个按钮的用户控件，我想在调用用户控件的页面中获取 raiseevent。一切正常，除了当我单击用户控件上的按钮时我无法捕捉到事件。
我对 uc 的标记：
<%@ Control Language="VB" AutoEventWireup="false" CodeFile="MsgBox.ascx.vb" Inherits="MsgBox" ClassName="MsgBox" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="act" %>

.Modal_trans {
opacity: 0.8;
filter: alpha(opacity=60);
}
</style>
<link rel="stylesheet" type="text/css" href="../Styles/StyleSheet.css" />"
<asp:Panel ID="PopPanel" runat="server"

<asp:Label ID="lblTitle" runat="server" Text="Help"></asp:Label>
</th>
</tr>
<tr>

和背后的代码
Partial Class MsgBox
Inherits System.Web.UI.UserControl
Public Shared IconInfo, IconExec, IconQues, IconError As Object
Public Property MsgText As String
Get
Return lblMsg.Text
End Get
Set(ByVal value As String)
lblMsg.Text = value
End Set
End Property
Public Event MsgButtonClick(ByVal buttonName As String)
Protected Sub MsgButtonOKClick(ByVal sender As Object, ByVal e As EventArgs) Handles ok.Click
RaiseEvent MsgButtonClick("ok")
End Sub
Protected Sub MsgButtonDenyClick(ByVal sender As Object, ByVal e As EventArgs) Handles no.Click
RaiseEvent MsgButtonClick("no")
End Sub
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
IconInfo = "Show Information Icon"
IconExec = "Show Warning Icon"
IconQues = "Show Question Icon"
IconError = "Show Error Icon"
End Sub
Public Sub Pop(Optional ByVal Message As String = "", Optional ByVal Mode As Object = "IconInfo", Optional ByVal Title As String = "Info Message")
no.Visible = False
ok.Text = "Ok"
If Title <> "" Then
lblTitle.Text = Title
End If
Select Case Mode
Case "IconInfo"
Image.ImageUrl = "../images/info.png"
no.Visible = False
ok.Text = "Ok"
lblTitle.Text = "Info"
Case "IconExec"
Image.ImageUrl = "../images/exc.png"
no.Visible = False
ok.Text = "Ok"
lblTitle.Text = "Warning"
Case "IconQues"
Image.ImageUrl = "../images/ques.png"
no.Visible = True
ok.Text = "Yes" lblTitle.Text = "Question"
Case "IconError"
Image.ImageUrl = "../images/error.png"
no.Visible = False
ok.Text = "Ok"
lblTitle.Text = "Error"
End Select
PopUp.Show()
End Sub
Protected Sub No_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles no.Click
PopUp.Hide()
End Sub
也测试了变化
Public Event MsgButtonClick As EventHandler
Protected Sub MsgButtonOKClick(ByVal sender As Object, ByVal e As EventArgs) Handles ok.Click
RaiseEvent MsgButtonClick(sender, e)
End Sub
Protected Sub MsgButtonDenyClick(ByVal sender As Object, ByVal e As EventArgs) Handles no.Click
RaiseEvent MsgButtonClick(sender, e)
End Sub
在我的页面中，它是带有更新面板的母版页的内容页面，我尝试通过后面的代码来捕捉事件
Protected Sub test() Handles PopMsg.MsgButtonClick
Response.Write("Done")
End Sub
在页面上的标记中，我将控件直接放在 UpdatePanel 的 ContentTemplate 后面
<msg:PopInfoMsg ID="PopMsg" runat="server" />
并通过单击按钮调用 UC
Protected Sub HelpMsg()
PopMsg.MsgText = "My first Test<br/> Cheers<br/>"
PopMsg.Pop("", "IconInfo", "Info")
End Sub
控件按预期打开，但是当单击“确定”按钮时，控件在没有事件的情况下关闭。在 VS 中，我尝试在 Button Click 处进行调试，但代码没有运行到这一点。我哪里错了？最近几天让我很困惑...
干杯，亚历克斯
