vb.net - 从内容页面从 MasterPage 调用 Sub

Question

引用:ASP.Net : How to call a Master page event handler from Content page event handler?

问题:SiteAssessment.btnNext_Click(sender, e) 无法访问，因为它受到保护，但我看不到？？!!

好的，aspx.vb 的顶部是

Imports System.Data.SqlClient


Partial Class Assessment

    Inherits System.Web.UI.Page

    <%@ MasterType VirtualPath="~/SiteAssessment.master" %>

    Public Sub btnNext_click(sender As Object, e As System.EventArgs)

         SiteAssessment.btnNext_Click(sender, e)

    End Sub

母版页 (SiteAssessment.master.vb)

Partial Class SiteAssessment

    Inherits System.Web.UI.MasterPage


    Public Sub btnNext_Click(sender As Object, e As EventArgs)
        'Do Stuff Here

        If Session.Item("questionbtn") Is Nothing Then
            Session.Item("questionbtn") = 1
        Else
            Session.Item("questionbtn") = Session.Item("questionbtn").ToString + 1
        End If

        'Call PrcchkListAnswers()

        'Call PrcQuestionText()

        Dim lblSession As Label = DirectCast(MainContent.FindControl("lblSession"), Label)
        lblSession.Text = Session.Item("questionbtn").ToString

    End Sub

Answer 1

首先，您需要将 MasterType 标记放在 .aspx 标记页面的顶部(而不是 .vb 代码隐藏)。

其次，使用 Page.Master Property 引用母版页。然后您就可以访问您的方法:

Me.Master.btnNext_Click(sender, e)
