HtmlViewer raises a Loaded event to notify the listeners that the internal initialization is complete. Following is the sample code to raise a Loaded event:

Note: You can obtain the ClientId from the WebViewer control.

In order to work with the API, obtain an instance of the ViewerViewModel first, using the GetViewModel(clientId) javascript function that searches ViewerViewModel array through the clientId. This function throws an exception if there is no ViewerViewModel with the requested clientId available.

Use code like the following to call an instance of the ViewerViewModel:

var viewModel = GetViewModel(clientId);

After obtaining the ViewerViewModel, the code can call API methods and properties.
