    Hey,

    For my current application security of viewed PDF files is the major aspect.

    I added the following settings with PdfSharp

                securitySettings.PermitAccessibilityExtractContent = false;
                securitySettings.PermitAnnotations = false;
                securitySettings.PermitAssembleDocument = false;
                securitySettings.PermitExtractContent = false;
                securitySettings.PermitFormsFill = false;
                securitySettings.PermitFullQualityPrint = false;
                securitySettings.PermitModifyDocument = false;
                securitySettings.PermitPrint = false;

    It seems that the Telerik Component does not recognize these settings.

    So is it possible to deactivate the strg+a (select all) / strg+c (copy) shortcuts

    Buttons for Printing and Select Text are already deactivated.

    Thanks

    Matthias

    Hi Matthias,

    Thank you for writing.

    In this case you can use the SelectionChanged event and prevent the user from selecting (copying) anything:
    void PdfViewerElement_SelectionChanged(object sender, EventArgs e)
    {
        radPdfViewer1.Document.Selection.Clear();
    }

    I hope this helps. Should you have any other questions do not hesitate to ask.
