Unable to debug a web part (User Control file - .ascx.cs)

Asked By: Rickie Bray Date: May 17, 2008 Category: Sharepoint Views: 1417

1) I created a Class Library with a class and given path of User control,
overridden CreateChildControls(), RenderContents() methods, inherited WebPart
class.
Created User control in a separate web site.
2) I copied the UserControl files (.ascx and .ascx.cs) and pasted these files in
C:\Inetpub\wwwroot\wss\VirtualDirectories\8081\UserControls folder
3) Copied the dll and pasted in
C:\Inetpub\wwwroot\wss\VirtualDirectories\8081\bin folder and assembly folder
C:\WINDOWS\assembly
4) Added <safeControl> tag in web.config file located at
C:\Inetpub\wwwroot\wss\VirtualDirectories\8081
5) Kept breakpoints to the class in the class library and attached worker
process w3wp.exe.
6) Loaded the web part in the webpart gallary and clicked on the link for
preview, it has taken to the class and i am able to do debug class file, but not
able to debug usercontrol file.
I need to do debug .ascx.cs file, how can I do it. Am I doing in the correct
way?

I'm pretty sure to debug the ASCX file you are going to need the source
files added to the project you are debugging from. It sounds like you
are trying to debug the ASCX code beside sheet from inside the Webpart
wrapper project. Also, DLLs should be deployed to either the GAC or Bin
folder, but not both. If you deploy to the GAC you have the added
problem of making the PDB symbol file available for debugging since that
can't be added to the GAC directly.

Instead of creating a class Library, create a new web Application project
(NOT a new web site) instead. Then move all your class library
application objects into this new application.

If you create a web application project instead of a class library, Visual
Studio will more easily recognize the .ascx control. From your web part's
CreateChildControls(), you'll also be able to directly cast your .ascx
control class (instead of casting the generic UserControl).

This is one of the very few cicumstances where I create something other
than a Class Library.
