Properties Overview
The report viewer exposes various commands via the commands property.
Commands
Each command is an object with the exec() method being the one that actually triggers the command. The other two methods, enabled() and checked() return a bool value and can be used prior to executing a command or to find in what state the UI for the command should be.
<tr-viewer #viewer1 />
...
<button (click)="viewer1.commands.print.exec()">Print</button>
The example above creates a Print button and in the click event handler invokes report viewer print command.
The
exec()method of the command needs to be called. For more information, please check the command article.
