How to get label or textbox control from .aspx page in .ascx user control page

 How to access controls from .aspx in .ascx user control page  
 Here i am showing a simple example how can we access controls from aspx in .ascx page  
 First i have created a WebUserControl.ascx user control page which contain a button.  
 WebUserControl.ascx page  
 <%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="WebUserControl" %>  
 <table>  
   <tr>  
     <td>  
       <asp:Button ID="btn_addUC" runat="server" Text="Add" OnClick="btn_addUC_Click" />  
     </td>  
   </tr>  
 </table>  
 Write below code in code behind   
 WebUserControl.ascx.cs page  
 protected void btn_addUC_Click(object sender, EventArgs e)  
 {  
      Button btnSender = (Button)sender;  
      Page parentPage = btnSender.Page;      
      TextBox txt = (TextBox)parentPage.FindControl("txtName");  
      Label lbl = (Label)parentPage.FindControl("lblNAme");  
      lbl.Text = txt.Text;  
 }  
 Take a another test_page.aspx page and register the above user control in it.as given below:  
 test_page.aspx page  
 <form id="form1" runat="server">  
      <div>  
           <uc1:WebUserControl runat="server" ID="WebUserControl" />  
      </div>  
      <div>  
           <asp:TextBox ID="txtName" runat="server"></asp:TextBox><br />  
           <asp:Label ID="lblNAme" runat="server" Text="Label"></asp:Label>  
      </div>  
 </form>  
      Run and test the application.
