Why is it that the telerik report designer is locked down and cannot be used as a set of controls in a custom application as any other telerik control. We would like to use the report designer controls in an application we make to give it our look and feel and so we can give it the functionality we require. Why limit your customers by locking down your report designer. One of the great things about telerik is a great set of products and customer support. If we had a way to get at the Telerik.ReportDesigner.Core.dll we can figure our where the controls are and display them in our app. I don't understand the marketing behind the locked down report designer. How does it benefit your customers? You can still have a locked down designer for those customers that don't want to customize it. Providing access to Telerik.Reporting.Core.dll will give your customers the ability to customize the report designer to their needs. Telerik sells controls that customers use to make applications that they sell, so whats the difference with the designer?
