.NET Framework - Class of UserControl not found in Page

Asked By Mathias Fritsch

29-Mar-08 05:11 AM

I am using FindControl in my page and try to cast the control found to
a specific control.

((Controls_Footer)this.Master.FindControl("Footer1")).OnPrintToPdf +=
new Controls_Footer.PrintToPdf(Footer1_OnPrintToPdf);

This works but after a while doesnt compile anymore in Visual Studio.


I can then change the web.config to compile in release and it compiles
again - well most of the time.

It compiles without problems on my buildserver which uses a
webdeployment - project.

What is wrong here?

you a counting on compile batching (compiling pages into one dll) to resolve
reference. you can select rebuild or as you shoudl have done in the forst
place, add a reference to the in page

Alex,
All files are contained in one web. MasterPage and aspx-Page are in
the main folder.

Controls_Footer is located in subfolder called: Controls.

All files use the same namespace: B2BShop.Web.
The aspx and ascx files have a reference which uses the namespace in
the Inherit - Attribute.
(Inherits="B2BShop.Web.Controls_ProductDetail")

Another way to do this is by placing the .ascx file in the App_Code directory.

See:
http://odetocode.com/Blogs/scott/archive/2005/10/01/2293.aspx

...you don't even need a reference, although the ascx source must use inline code.
That isn't practical for you if you use codebehind in the ascx ( some.ascx.cs, for example ).

However, Bruce is right.

If you want to do it the way you're currently doing it, you must include a reference :


The Inherits statement doesn't provide a reference.

Thank you all: I added <%@ Reference Control="YourUserControl.ascx"
%>  and things are compiling now!
