无法在内容占位符页面中显示控件RBL

问题描述

拥有母版页和内容占位符页面。在占位符页面中，我有Checkbox。

如果勾选复选框，我希望显示RadioButtonList6。在下面的代码中，它不会发生在母版页的这种情况下。如果没有母版页运行，相同的代码工作正常。如何解决这个问题？

In have a master page and a content placeholder page. In the placeholder page, I have Checkbox.
If I tick the checkbox I want the RadioButtonList6 to be displayed. In following code it is not happenning in such circumstance with a master page. If run without a master page, this same code works fine. How to rectify this?

<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="checkboxtest6.aspx.cs" Inherits="checkboxtest6" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:UpdatePanel ID="UP1" runat="server"  >
<ContentTemplate>
<asp:TextBox ID="MyFirstTextBox" runat="server"></asp:TextBox>
<asp:TextBox ID="MySecondTextBox" runat="server"></asp:TextBox>
<asp:CheckBox ID="MyCheckBox" runat="server"   style="  margin-left:3px; "/>
<asp:RadioButtonList ID="RBL6" runat="server" OnSelectedIndexChanged="RBL6_OSIC"

                    RepeatDirection="Vertical"  AutoPostBack="true"

                    style="" >
                    <asp:ListItem>Deliver at the above address</asp:ListItem>
                    <asp:ListItem>Deliver at a different address</asp:ListItem>
</asp:RadioButtonList>
<script type="text/javascript" language="javascript">
    function ShowRBL6() {
    RBL6.style.display ="";
}
</script>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Content>

public partial class checkboxtest6 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        this.RBL6.Style.Add("display", "none");
        this.MyCheckBox.Attributes.Add("onClick", "ShowRBL6()");
    }
    protected void RBL6_OSIC(object sender, EventArgs e)// delivery options when 'send to guest' selected
    {
    }

推荐答案

function ShowRBL6() {
            if (document.getElementById('<% = MyCheckBox.ClientID %>').checked == true)
                document.getElementById('<% = RBL6.ClientID %>').style.display = "block";
            else
                document.getElementById('<% = RBL6.ClientID %>').style.display = "none";

        }

因此下一次点击也将用于取消检查将被处理。

so the next click will be also for unchecking will be handled.
