The code uses some of the objects defined in The Business Layer.

Inserting Documents Dynamically

You can insert contents of outer documents to your reports dynamically using doc tags. A doc tag denotes a placeholder within a template for a document to be inserted during run-time.

A doc tag can be used almost anywhere in a template document except text-boxes and charts.

An expression declared within a doc tag is used by the engine to load a document to be inserted during run-time. The expression must return a value of one of the following types:

  • A byte array containing document data
  • A Stream instance able to read document data
  • An instance of the Document class
  • A string containing a document URI

If an expression declared within a doc tag returns a stream object, then the stream is closed by the engine as soon as a corresponding document is loaded.

By default, a document being inserted is not checked against template syntax and is not populated with data. However, you can enable this by using a build switch as follows.

When build switch is used, the engine treats a document being inserted as a template that can access the following data available at the scope of a corresponding doc tag:
