Viewer tag

The viewer tag is the main tag that instantiates the CrystalReportViewer. It handles the creation of the viewer and allows you to set viewer properties through supported attributes.

Each instance of the viewer tag requires a report tag to specify the report to be displayed. If multiple instances of the viewer will be used on a single HTML page, each instance must be given a unique name, specified through the viewerName attribute.
