Does the Diagram Web Control have any special provisions for printing large diagrams?
The Diagram ASP.NET Web Server Control does not have any special provisions for printing large diagrams spanning multiple pages. This is because the ASP.NET DiagramWebControl renders the diagram as a static or interactive image, and the print options available to the client are restricted by the browser's support for printing images. For complex printing needs your ASP.NET application will have to provide a printing service that uses the diagram library's printing infrastructure and provides the client browser with a series of page-sized images that can be printed. The Essential Diagram base library has comprehensive printing support built into it that covers features such as pagination, page layouts, margins, headers & footers, zooming, print-to-fit, preview, etc. While this functionality is geared towards the Windows Forms printing model, the implementation itself is built into the base Diagram library and can be accessed by the Diagram Web Control as well.
We will provide a sample demonstrating this approach in a future version of the product.
