Server control not accessible in code-behind?

I have a web page that I am converting from classic ASP to ASP.Net. There are a bunch of "Select" controls (DropDown Boxes) that I am changing to DropDownList controls. I have set the "runat='server'" in all of these controls. However, when I go to the code-behind, they are not visible/accessible. I have tried to "clean" the solution and rebuild it and the controls still won't show. Any ideas?

Thanks,

Does anyone have any ideas on this? I'm really under the gun here and need to get this project finished. Sorry for the nagging!

is autopostback = "true" in that line somewhere?

No, the autopostback = true isn't in the declaration of the control and I don't want it to be an autopostback either.

without post back certain controls will not fire the event. do you have autoeventwireup set to true?

No I don't have autoeventwireup = true....

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Myform" %>

should be at the top of your ASPX file. Try that.

also declare your event signature in the control layout, so for a text box OnTextChanged="EventYouDefined"

Unfortunately that did not make a difference!

DDL has to be marked as autopostback = true to fire the selected index changed event.

Let me try that and see what that does!

That did not affect it either.

Not showing a runat server control may occur if you are running C# and VS2008. Is it possible that you have this combination?

when you say running C#...are you referring to that being the development language that I am using for this particular project? If so, I'm using VB.Net. But I am using VS 2008.

language should not matter to the HTML, i just happen to write this one in C# is all.

can you post the offending markup for the control??

Here is the markup for the just one of the controls. There are a handful of others just like it.

Code:

---

                                    <asp:DropDownList ID="drpClient" runat="server" style="width: 260px">
                                        <asp:ListItem Value="0">--- Select Client ---</asp:ListItem>
                                    </asp:DropDownList>

---

Code:

---

<asp:DropDownList ID="ddlCheckType" runat="server" Width="132px" OnSelectedIndexChanged="ddlCheckType_SelectedIndexChanged" AutoPostBack="True">
         
</asp:DropDownList>

---

this declaration workes in 12, should work in 08 too, i just declare my list items values in code instead of markup, but that part dont matter.

I showed this code to another one of our developers and he added it to his code and tried accessing it in the code-behind and didn't have any trouble. He did some inquiring and the census was that it appears to be a setting within VS 2008. I submitted a ticket to Experts-Exchange as well.

that could be...generally you print out the code due for upgrading and rewrite it. upgrading from classic to .net would involve more headaches than just redoing the whole thing.

Do you have the latest service pack installed?
Also if you add a dropdownlist, go to the designers mode and double click at it, what happens?

I actually just went into the designer.vb of the page and manually inserted the controls. It didn't take to long. I will try what you suggested Sapator just to see what happens.

Thanks
