Umbraco - Could not load type 'usercontrols_NewContactUs'

894 views Asked by At

I am trying to duplicate an existing Form in Umbraco (Contour is not installed). I have copied the following files:

from: \my-site\usercontrols\Common\ContactUsForm.ascx <%@ Control Language="C#" AutoEventWireup="true" Inherits="usercontrols_ContactUs" Codebehind="ContactUsForm.ascx.cs" %>

to: \my-site\usercontrols\Common\NewContactUsForm.ascx <%@ Control Language="C#" AutoEventWireup="true" Inherits="usercontrols_NewContactUs" Codebehind="NewContactUsForm.ascx.cs" %>

from: \my-site\usercontrols\Common\ContactUsForm.ascx.cs public partial class usercontrols_ContactUs : System.Web.UI.UserControl {...}

to: \my-site\usercontrols\Common\NewContactUsForm.ascx.cs public partial class usercontrols_NewContactUs : System.Web.UI.UserControl {...}

I have created a macro which points to the NewForm, and added the macro to a new page.

I don't have Visual Studio installed - could there be a compilation error in my codeBehind class?

Error details are below:

Macro created and added to form gives error: Error creating control (usercontrols/Common/NewContactUsForm.ascx). Maybe file doesn't exists or the usercontrol has a cache directive, which is not allowed! See the tracestack for more information!


Error reading usercontrols/Common/NewContactUsForm.ascx The following list shows the Public Properties from the Control. By checking the Properties and click the "Save Properties" button at the bottom, umbraco will create the corresponding Macro Elements.

Yup, it's a compilation issue. The class NewContactUsForm doesn't exist until you compile it. In a bind, you could move the code from NewContactUsForm.ascx.cs into a C# script block directly on NewContactUsForm.ascx and remove the codebehind="..." and inherits="..." refrences entirely. That way you won't have to compile.
