usercontrol problem

P: n/a
When trying to run my web project, I get the following
error:

Parser Error
Description: An error occurred during the parsing of a
resource required to service this request. Please review
the following specific parse error details and modify your
source file appropriately.

Parser Error Message: The base class includes the
field 'ValidateLogin', but its type
(YTCIWebUserControls.UserLogin) is not compatible with the
type of control (ASP.UserLogin_ascx).

Source Error:
Line 13: <form id="Login" runat="server">

All this is, is a usercontrol with a login screen as
follows:

I didn't read into your code cause there's a lot but from
the error message it looks as if you specify ValidateLogin
control of type YTCI:LoginControl in your aspx page, but
in the codebehind member ValidateLogin is declared of some
other type. this happens a lot when your member variables
are out of sink with the id's in the page. for instance if
you have <asp:Label id="lbl"> but in the code you declare

TextBox lbl; -> then you will get a runtime error...

I FINALLY figured it out!

All I did was change the line:

Protected ValidateLogin As YTCIWebUserControls.UserLogin
to
Protected ValidateLogin As UserLogin

in my codebehind page....
