Kentico 7 > Kentico 8.. "ValidationHelper' does not exist in the current context"

Ipswitch Web asked on September 26, 2014 20:28

Hi there,

Along with some Transformation errors after upgrading from Kentico 7 to 8.. I see most of my custom Web Parts won't load. The following error is in the Event Log:

    Message: c:\inetpub\kenticodev\www\CMS\IPSComponents\CMSWebParts\Pages\Widget3FeaturedResource.ascx.cs(26): error CS0103: The name 'ValidationHelper' does not exist in the current context

and is the case for all the custom Web Parts.. anyone see this before? Thanks.

Check out the List of API Changes from 7-8. Then search for ValidationHelper. You'll find it is now used in a different namespace CMS.Helpers.
