Just a guess but I'd say that (in your codebehind or somewhere in your script tags) you have an object named 'ConstructIDLabel' and it is of type System.Web.UI.WebControls.Label. So, you have a private member variable of one type and a static control declaration of a different type. Change the private member variable so that it is of type System.Web.UI.WebControls.TextBox and all will be well.

That was it. There were quite a few declares left after I deleted the original controls.
Thanks.

I had this problem too.

The problem was that I changed the type of a server control instance on an aspx page, but did not change the id.

Thus, the code-behind class for my aspx page still had the declaration for the control with the old type, while the aspx was claiming it was something else.

Invoking the desiger in VS.NET updates the declaration to the right type (or you could change it by hand in the code behind.

Thanks for the posting Alex.
