我想创建一个具有工具栏（添加、编辑、删除、批准、取消批准）以及网格视图的母版页，如下所示。此母版页将有很多子级。我想重用gridview和工具栏..而不是将它们都添加到我创建的每个页面中。

使用上面的母版页的子页示例。
<%@ Page Title="" Language="vb" AutoEventWireup="false" MasterPageFile="~/JSPayroll/JSPSite.Master" CodeBehind="PaymentRules.aspx.vb" Inherits="SSPayroll.PaymentRules" %>
<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
</asp:Content>
<asp:Content ID="DS" ContentPlaceHolderID ="DataSource" runat ="server">
<asp:EntityDataSource ID="EntityDataSource1" runat="server" ConnectionString="name=sspEntities" DefaultContainerName="sspEntities" EnableDelete="True" EnableFlattening="False" EnableInsert="True" EnableUpdate="True" EntitySetName="GeneralRules">
</asp:EntityDataSource>
</asp:Content>
基本上我想做的是..在我的子页面中，只需为每个页面配置数据源，将其从母版页附加到gridview并执行我的任务..添加，编辑，删除（我的母版页中的按钮） . 我对此并不陌生，并且真的不知道如何去做。一些帮助将不胜感激。此外，如果有人能告诉我我在做什么实际上是有意义的，而不是向我创建的每个页面添加网格视图和工具栏。请告诉我。谢谢你。
已编辑 - 有答案。
Dim ContentPlaceHolder As ContentPlaceHolder
Dim gv As GridView
ContentPlaceHolder = CType(Master.FindControl("GridViewPlaceHolder"), ContentPlaceHolder)
If Not ContentPlaceHolder Is Nothing Then
gv = CType(ContentPlaceHolder.FindControl("GridView1"), GridView)
If Not gv Is Nothing Then
Dim es As EntityDataSource = EntityDataSource1
gv.DataSource = es
gv.DataBind()
End If
End If
