Requirements

This component is Portable. It runs both on Windows (WPF) and on Web Pages hosted in any platform.

Configuration

  1. Go to Displays / Draw.
  2. On the Components Panel, select Viewer, then PdfViewer.
  3. Click or drag-and-drop it on the Drawing area to use it.
  4. Double-click the object to open the configuration window.

The only configuration required is to insert the URL in the URL field, which will map to the source of the PDF, facilitating the display of online PDF files.

Customization

Handling the URL via CodeBehind

To access the URL for PDF file on CodeBehind, use the LinkedValue property. This property provides the URL associated with the control.

If the URL originates from a Tag, it will be tokenized. To retrieve the actual URL, use the following methods:

string CustomUrl = TConvert.ToString(TK.GetObjectValue(T.Wpf.RunServices.ConfigHelper.UntokenizeObjectName(LinkedValue)));



The Validate() method has been replaced by StartRuntime for all controls, including TPdfViewer.

TPdfViewer pf = this.CurrentDisplay.GetControl("pd") as TPdfViewer;
pf.Validate();

When initializing or updating a control, use StartRuntime() instead of Validate:

TPdfViewer pf = this.CurrentDisplay.GetControl("pd") as TPdfViewer;
pf.StartRuntime();




Runtime Execution 

When running the application, the PdfViewer Control fetches and displays PDF documents from specified URLs. Upon execution, the PdfViewer Control accesses the provided URL and renders the PDF content within the application.
