Cannot convert type 'ASP.login_aspx' to 'System.Web.UI.WebControls.Login'

[Tim Cartwright]

I have a page that has the login control on it, nothing else. This page inherits from a master page, neither page has any code in it. This page works perfectly when running on the WebDev debug web server. I am able to log in. However after publishing the page to my local IIS, it results in the below error. This error is occurring on the Visual Studio.Net 2k5 release version, but did not occur on the beta 2, same code.

A point of interest, is that I uninstalled IIS, then re-installed it after a recent system rebuild (which I did to completely remove the beta), and I reinstalled asp.net to IIS afterwards.

First the html :

Howdy,

I hit the same issue just now...and you are the only one I could fin
who was having the same problem. The good news is I figured it out...
thought it might have to do with the name of the page (based on th
error we were both receiving). I renamed my page from Login.aspx t
MemberLogin.aspx. I recompiled and deployed. Everything worked!!!!

Based on the name of your page I assume this will work for you.

Good luck

WOW MUAHAHAHAHAHAHHA - Interesting................. I also find this
interesting that this code was working in Beta 2, but now is broke.

 

[Dima]

Yeah! I also encontered the same problem...

Hey Guys,

Finally, I found a group of people having the same error!
It's been two days on this already and nothing...

sholder,
I am happy for you man, because I tried the same thing with no positive
results.
When changing the name of the file I also had to change web.config,
otherwise it keeps looking for "Login.aspx", which according to MS it
is the default login path for vs2k5.

Hopefully, there is a different try for this... hopefully!

Cheers

I finally GOT IT !!!
Simply using a different name for the page is not enough.
Here is the solution I found on Microsoft's lab website:

If you have used a Page that effectively uses a codebehind classname
that is the same as say the Login control, that is Login, e.g. your
page was called Login.aspx, then when you pre-compile (publish) the web
site as an updateable web site, the aspx is retained and tries to
compile against a type called Login in the code behind. It does not
resolve to be that in the codebehind assembly

Try using a classname for your codebehind and defined in the inherits
that does not clash with a type in System.Web, e.g. LoginPage, or
qualify the class and therefore the inherits statement with a
namespace, e.g.

<%@ page ... inherits="theNs.Login" %.

namespace theNs { public partial class Login : System.Web.UI.Page { ..
} }

Now... going to the next challenge...

Take care you all!
