C1FlexReport uses the C1.Win.C1Document assembly, that further exposes the following two classes, which are base classes for C1FlexReport and C1SsrsDocumentSource:

• C1Document: represents ComponentOne document. Its main functions are as follows:

  • Persists the document as a RenderObjects tree.
  • Renders the document content.
  • Highlights the Text selection.
  • Checks a specific location of an object with respect to other elements through methods such as HitTest.
  
  C1Document is similar to our WinForms’ C1Framework library. It is a set of rather low level utility classes used by other components. Currently it is used by C1SsrsDocumentSource, C1SsrsViewer, and C1FlexReport.

• C1DocumentSource: provides functionality to work with different documents and report types. It is a base class to build C1Document objects. Its main functions are as follows:

  • Provides infrastructure for asynchronous rendering of documents.
  • Provides parameter support while generating the document.
  • Provides support for text search in the generated document.

  C1FlexReport is derived from C1DocumentSource. It uses C1DocumentSource to provide asynchronous rendering, parameter support and text search. This also means that it will be easy to port C1FlexReport to other platforms (XAML).
