Changing base class from default system.web.ui.page in .net 2.0

[Techotsav]

Hi guys

I do have following class structure

xxx.RoleManagement : xxx.RMUser.
xxx.RMUser : System.web.ui.page

These classes are added in solution as different project. Now what i am
trying is to change .aspx page's base class from default
system.web.ui.page to xxx.rolemanagement. But it is throwing following
error -

#no suitable method found to override
#does not implement interface member
'System.Web.IHttpHandler.IsReusable'
#Make sure that the class defined in this code file matches the
'inherits' attribute, and that it extends the correct base class

I have changed inherit attribute in .aspx as well as declared intended
page's base class to xxx.RoleManagement

Any help will be highly appreciated

Thanks and regards
