Hi everybody,

I have a page that tries to instantiate a custom button class using the following code:

 UCD_volunteerBtn Vol;
                        Vol = (UCD_volunteerBtn)Page.LoadControl("/UCD/volunteerBtn.ascx");
                        Vol.PersonID = (int)P.PersonID;
                        Vol.IsEvent = false;
                        Vol.Program = Prog;
                        Vol.PSession = PrgSesssion;
                        Vol.CssClass = "nav" + Theme.CSSPrefixClass;

It gives me this error:

Error 1 The type or namespace name 'UCD_volunteerBtn' could not be found (are you missing a using directive or an assembly reference?) C:\Development\Visual Studio 2005\WebSites\FCFront\UCD\EventProgramMod.ascx.cs 105

I found the class for this button, but I'm not sure what should I do.

Thanks a lot in advance.

Also why when I build the solution, it succeed, but when I re-build it gives me the above and bunch of other related errors?
