retreiving the value of hidden field from .ascx file to ascx.cs file

Dec 30 2009 9:58 AM

My code in program.ascx is
<form id="form1" runat="server">
<ItemTemplate>
      <div>
       <input id="inpHide" type="hidden" runat="server" />  
       <asp:DropDownList id="dd" runat="server" onselectedindexchanged="dd_SelectedIndexChanged" onChange="ConfirmIt()"  AutoPostBack="true" >
        <asp:ListItem Value="Pending">Pending</asp:ListItem>
        <asp:ListItem Value="Yes">Yes</asp:ListItem>
        <asp:ListItem Value="No">No</asp:ListItem>
       </asp:DropDownList>
       </div>
      </ItemTemplate>
      
     
     </asp:TemplateColumn>
</form>
My javascript function is
 <head runat="server">
<SCRIPT language="javascript">
 function ConfirmIt() {
             var x = confirm("Do you Want to notify changes to User ??");
             var control = '<%=inpHide.ClientID%>';
             if (x == true) {
                 document.getElementById(control).value = "1";
             }
             else {
                 document.getElementById(control).value = "0";
             }
         }
 
</SCRIPT>
 
</head>
My code in the Program.ascx.cs
 protected void dd_SelectedIndexChanged(object sender, EventArgs e)
       {
         
          
           int DiagResult = int.Parse(inpHide.Value);
       
        if (DiagResult == 1)
        {
            //Do Somthing
            Response.Write("You Have Selected Ok");
        }
        else if (DiagResult == 0)
        {
            //Do somthing
            Response.Write("You have Selected Cancel");
        }
       
       
    }
 
In short whenever the dropdown list value changes,It should notify change to user.
I got the same code from this forum but they did it in page i.e.  aspx and aspx.cs.,Dat is working fine ...But when i am implementing in usercontrol like above (and integrating the code in my project) ..Its giving error as impHide is unknown in the following context.means the value is not retrieved from the Program.ascx file.I am unable to find the main cause.
Pls help me to solve this
Thanks...
