New ASP control not accessible in code behind

Sometimes when I add a new control in ASP it isn't accessible in the codebehind until I completely exit the website and reopen it in Visual Studio 2005.

Here's the latest one:
<asp:ListBox ID="lbStatus" Height="85px" Width="410px" AutoPostBack="false" CausesValidation="false" runat="server" Visible="true"></asp:ListBox>    

It is not available in the list of objects in codebehind.  And when I do "Me.lbStatus" it says it's not a member of my form.

I saved, did a Refresh from the Solution explorer, did a right-click -> refresh on the project name. Nothing works.  What's up with this?

I run into the same thing from time to time. I think this is some kind of funkiness in the Intellisence.  Here's what I do as a workaround when this happens to me, but I'd love to know if there is a better way.

1. In the .aspx page, set AutoEventWireup="true".
2. Click on a line below the page directed.  Anywhere will do.  It will trigger a refresh of the intellisence.
3. Go to your codebehind page and see if the control is now recognized.
4. If it is, reset the AutoEventWireup setting.

It can sometimes take a while for the Intellisence to recognize a control, but it should not happen to you all the time. I've had it on some occasions, but usually all I needed to do was go on typing and it would recognize it eventually.

Regards,
Max.

The wireup trick worked.  That's a reasonable workaround as opposed to closing/opening the entire folder.

Actually, just inserting or deleting a blank line in the aspx page works too.

Interesting...I guess if I just make it a habit to return after creating a control, this should happen anymore.

Thanks for the shorter workaround!
