inherits problem

[CRuser89]

Hello everyone,

I'm very new to asp.net so please be patient w/me. I have a login page called login.aspx that has the following line below. When I try to compile it, I get the error - Could not load type 'LoginPage.WebForm1'. The namespace LoginPage and class WebForm1 exists on the code behind. Below is the code behind. I've searched on google and see alot of solutions for this which says that you have to rebuild the application/project? I'm not sure how to do this. Can someone please help me? Thanks - Kathy:

Hello Prashant,

Thank you for your reply. I actually figured it out. I changed "CodeBehind" to "CodeFile" on the first line and it worked. However, when I compile it now, I get an error on the line below:

Error:
NullReferenceException was unhandled by user code
Object reference not set to an instance of an object


Code Line:
this.cmdSubmit.Click += new System.EventHandler(this.cmdSubmit_Click);


Can someone please help me figure out what's wrong?

Thanks,
Kathy

Did you check it with recreating the control (Submit button)?
