Unable to view codebehind in a ascx file

I downloaded an open source project in ASP.NET language.

And I couldn't find any Codebehind file for example inside the Login.aspx the Codebehind is Login.aspx.cs but I cant find it anywhere in the source file. and the Line Codebehind="Login.aspx.cs" identified as "File Login.aspx.cs was not found" but yet the function is still working.

Where can I access those .cs file?

Solution

It seems that code you are looking for is compiled in DLL files. Try to get full source code instead of compiled one.

As mentioned by VKX, download link would help...
