# ControlID is not recognized in code behind

This is my [asp](https://www.mindstick.com/articles/751/introduction-to-asp-dot-net-mvc) 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](https://www.mindstick.com/forum/2199/call-javascript-s-function-from-code-behind), I am not able to type this callDispositionSelector. In other words, [visual studio](https://www.mindstick.com/articles/12378/visual-studio-for-mac-is-out-of-beta-preview-now-officially-available) doesn't recognize that id.

Hi tanuj, \
try this:\

protected void lst_ItemDataBound(object sender, ListViewItemEventArgs e)

{

if (e.Item.ItemType == ListViewItemType.DataItem)

{

DropDownList ddl= (DropDownList)e.Item.FindControl("callDispositionSelector");

}

}
