ControlID is not recognized in code behind

Question

This is my asp code

<tr class="footer" runat="server">
    <td colspan="4" runat="server">* By WWW.Play.org
       <asp:DropDownList AutoPostBack="true" runat="server" ID="callDispositionSelector" OnSelectedIndexChanged="callDispositionChanged">
           <asp:ListItem Value="-1">Select Disposition Reason</asp:ListItem>
           <asp:ListItem Value="1">Reservation</asp:ListItem>
           <asp:ListItem Value="2">Change of Reservation</asp:ListItem>
           <asp:ListItem Value="3">Cancellation</asp:ListItem>
           <asp:ListItem Value="4">Wait List</asp:ListItem>
           <asp:ListItem Value="5">Other</asp:ListItem>
       </asp:DropDownList>
    </td>
</tr>

In code behind, I am not able to type this callDispositionSelector. In other words, visual studio doesn't recognize that id.

I tried clean, rebuild, restart visual stuidio but nothing helps.

I tried change the id to another name but still not recognizable.

I tried deleing the designer , and then regenerate it but still the same problem

i tried restart the windows but still the same problem

Note

this controller exist in Item Template in asp.ListView

Find your dropdownlist control in listview's itemdatabound event like below

protected void lst_ItemDataBound(object sender, ListViewItemEventArgs e)
 {
       if (e.Item.ItemType == ListViewItemType.DataItem)
        {
            DropDownList ddl= (DropDownList)e.Item.FindControl("callDispositionSelector");
        }
 }

in my list view there is no `Item`. I mean I can'd do this `listviewID.Item` – Marco Dinatsoli Mar 29 '14 at 07:31
@MarcoDinatsoli, Is dropdownlist available inside of listview item template or not?Please confirm. – RGS Mar 29 '14 at 07:33
yes it is in listview, then in item template, then in tr , then in td, but i mean i just can see `listviewID.FindControl`, I can't see `listViewID.Item` – Marco Dinatsoli Mar 29 '14 at 07:34
