I am new in ASP.NET, and I have a website which I opened it by MS Visual 2010. The problem is when I try to select a control element I can not because it seems behind `ContentPlaceHolder`. See the image below, what can I do!

Here is the code of the page:

```
<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
<title>Job Seekers : Search Job in Oman</title>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

    <asp:Table runat="server" Width="800" style="direction: ltr" Visible="False">
