Question

我有一个带有两个按钮的usercontroll，我想在我调用usercontrol的页面中获取raiseevent。一切正常，但是当我点击用户控件上的按钮时我无法捕捉到该事件。

我的uc标记：

    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

和背后的代码

    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

还测试了变化

Protected Sub test() Handles PopMsg.MsgButtonClick
    Response.Write("Done")
End Sub

在我的页面中，这是一个带有更新面板的母版页的竞赛页面我尝试在后面的代码中跟踪事件

<msg:PopInfoMsg ID="PopMsg" runat="server" />

在页面上的标记中，我将控件直接置于UpdatePanel的ContentTemplate后面

Protected Sub HelpMsg()
    PopMsg.MsgText = "My first Test<br/> Cheers<br/>"
    PopMsg.Pop("", "IconInfo", "Info")
End Sub

点击按钮

呼叫UC

function getRow(svcName, rowId)
{
    // Mark in progress
    $("#" + rowId).html("<td colspan='5'>" + svcName + "<i class='fa fa-refresh fa-spin fa-1x fa-fw'></i></td>").addClass('info');

    // Get the HTML
    $.ajax(
        {
            type: 'get',
            dataType: 'html',
            url: svcName,
            error: function (jqXHR, textStatus, errorText) {
                $("#" + rowId).text("Error " + errorText + " (" + svcName + ")");
                var row = $(".service-table").DataTable().row("#" + rowId);
                row.invalidate('dom');
            },
            success: function (response, textStatus, jqXHR) {
                // This response is visible in the table 
                // UNTIL I sort the table, at which time it's the temporary 
                // version of the row, above, which is restored 
                // from the dataTable cache.
                $("." + rowId).replaceWith(response);
                var row = $(".service-table").DataTable().row("#" + rowId);
                row.invalidate('dom');
                //row.draw('row');
            }
        }
    );

}

控件按预期打开，但是单击“确定”按钮时控件关闭而没有事件。在VS中，我尝试在Button Click上进行调试，但代码没有运行到这一点。哪里错了？最后几天让我感到困惑......

干杯，亚历克斯

usercontroll上的按钮不会触发/引发事件
