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 triggers the command.

The other two methods, enabled() and checked() return a boolean value and can be used before executing a command or to find in what state the UI for the command should be.

HTML

<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.
