This is the same as an existing feature request, which was marked as completed but it doesn't achieve what was originally requested.
The UI for ASP.NET MVC OrgChart component is missing functionality found in the UI for ASP.NET AJAX product.
The demos only show a small organisation dataset. With a large dataset (including up to 5 levels), I found the current MVC solution becomes unusable. For example, the vertical/horizontal scroll bar becomes tiny and navigation becomes difficult.
The extra functionality available in the AJAX works around issues, such as, zooming in/out and solves other basic requirements, such as Export to PDF.
Please make the AJAX Functionality and Application Scenarios available in the MVC product.
