I'm trying to create a custom page and have a link in the portal to this page.
This page will be on the same website and share the same look and feel as the rest of the portal.
When trying to use the PortalContent Master Page for my custom page, I received an error.
System.InvalidCastException: Unable to cast object of type 'ASP.MyCustomPage_aspx' to type 'SmarterTrack.HelperClasses.CustomPage'.
at SmarterTrack.MRS.MasterPages.PortalContent.OnPreRender(EventArgs e)
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
Short of creating a MasterPage from scratch (and having to update it each time whenever there is a ST update), is there a recommend way to implement Custom Pages. Any helps or links would be greatly appreciated.
