如何更改master中WebParts中自定义控件的值。

content页 tt.aspx

<%@ Page Language="VB" MasterPageFile="~/master3.master" AutoEventWireup="false" CodeFile="tt.aspx.vb" Inherits="tt" title="Untitled Page" %>

<%@ Register Src="usercontrol/menuSysManage.ascx" TagName="menuSysManage" TagPrefix="uc1" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

    <asp:Button ID="Button1" runat="server" Text="sys" Width="160px" />

</asp:Content>

对应的tt.aspx.vb

 Partial Class tt

    Inherits System.Web.UI.Page

    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim wweb As WebPartZone

        wweb = CType(Master.FindControl("webpartzone1"), WebPartZone)

        Dim part As WebPart

        part = wweb.WebParts.Item(0)  

        Dim dd As ASP.menuSysManage   

        dd = CType(part.FindControl("MenuSysManage1"), ASP.menuSysManage)

        dd.Visible = False

  End Sub

End Class

注意：menuSysManage是我的自定义控件名称
