Customization

Get Object Control in CodeBehind

This is how you get control of this object in CodeBehind:

TPdfViewer _pdfViewer = this.CurrentDisplay.GetControl("<objectUid>") as TPdfViewer;

where, <objectUid> will be the object Uid defined in object properties. 

Some addiitonal properties to use with TPdfViewer:

/// <summary>
/// Defines factor of zoom to be applied, where 1 means 100%
/// </summary>
public double ZoomFactor { get; set; }

/// <summary>
/// Defines the zoom mode for the PDF viewer
/// </summary>
public ePdfViewerZoomMode ZoomMode { get; set; }

/// <summary>
/// Determines whether the horizontal toolbar is displayed
/// </summary>
public bool ShowHorizontalToolbar { get; set; }

/// <summary>
/// Determines whether the vertical toolbar is displayed
/// </summary>

public enum ePdfViewerZoomMode
{
    /// <summary>
    /// Displays with default zoom behavior
    /// </summary>
    Default = 0,

    /// <summary>
    /// Fits the entire page in the viewer
    /// </summary>
    FitPage = 1,

    /// <summary>
    /// Fits the width of the page in the viewer
    /// </summary>
    FitWidth = 2
}

Usage example:

TPdfViewer _pdfViewer = this.CurrentDisplay.GetControl("ui1") as TPdfViewer;
_pdfViewer.ZoomFactor = 2;
_pdfViewer.ZoomMode = TPdfViewer.ePdfViewerZoomMode.FitPage;
_pdfViewer.ShowHorizontalToolbar = false;
_pdfViewer.ShowVerticalToolbar = false;

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)));

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.
