I am new to Sitefinity and have been asked to migrate a site from 3.6 to 5.2. The majority of the migration has gone very smoothly but I have an issue with existing ascx controls that I haven't been able to figure out.
When editing a control in 3.6 I can see and set control properties. Once these controls are migrated I no longer get the option to set these properties.
The properties have a Category attribute and the contols themselves inherit from UserControl.
Is there something that I need to do to this controls in order to view and set the properties in 5.2?
Any help much appreciated
