Dear team,
I am applying below options while creating pdf files:
• pdf.Security.AllowCopyContent = false;
• pdf.Security.AllowEditAnnotations = false;
• pdf.Security.AllowEditContent = false;
• pdf.Security.AllowPrint = false;
I have tried with both libraries c1.pdf and c1.wpf.pdf but it is not working.
I am still able to copy content are print file.

Hello Mayur,
I used the attached application with the latest C1 builds but could not observe the issue. The attached video shows the scenario observed at my end.
Kindly test the sample and if the issue persists, modify and share it back so that I can observe the issue and assist you further.
Regards,
Esha

Hello,
Yes, this is possible using PdfSignature class.
Please refer the sample “PdfSignature” shipped along with ComponentOne suite. On your machine with C1 installed, it should be at the default location: C:\Users[UserName]\Documents\ComponentOne Samples\WinForms\C1Pdf\CS\PdfSignature
I have also attached the same for your reference.
Hope it helps.
Best Regards,

Hello,
C1Pdf and C1PdfViewer for WPF does not support digital signatures. However, you can set passwords with C1Pdf for WPF using the “Security object”. Following is the sample code that can be used :
myPdf.Security.OwnerPassword ="zzzz";
myPdf.Security.UserPassword ="xxx";

Hello,
C1Pdf for WPF does not support digital signatures.
WinForms version of the controls can be used for the same.

So to use Digital signature Do I need to buy licence for whole WinForm edition Or only Digital signature component can be purchased?

Hello,
You would need a license for the entire WinForms edition to use the C1Pdf control for WinForms.
I would also like to introduce to you “Grapecity Documents for PDF” that is a part of GrapeCity Documents that handles majority of the PDF related needs. The extensive library is supported on .NET Standard 2.0 can be used to read, create, modify and save PDF files without using any external tool like Adobe Acrobat.
You can learn more about the same from here:
https://www.grapecity.com/en/documents-api-pdf
http://help.grapecity.com/gcdocs/gcpdf/onlinehelp/webframe.html#Overview.html
You can use Digital Signatures with GcPdf as well. This has been illustrated here:
https://demos.componentone.com/gcdocs/gcpdf/Samples/List#SignDoc/codeCS
Kindly contact our sales team for further license related information. They might be able to assist you better in this regard: https://www.grapecity.com/en/contact

Can we apply Watermark to PDF document using C1.pdf.

Hi,
No, watermarks cannot be added to a pdf using C1Pdf. However, this can be done using GcPdf. The below mentioned blog shows the comparison between the two controls :

Hello,
The evaluation message pop up appears in the following two cases:
If you are using the builds from your licensed version, this screen will be visible because of the second case mentioned above. It may be due to the licenses file not existing in the application, containing wrong information, or not being configured correctly.
First, try a full rebuild (Rebuild All from the Visual Studio Build menu). This will usually rebuild the correct licensing resources.
The entry for every C1 control used in the application at design time or run time should be present in the licenses.licx file of the project. You may want to add this entry related to C1Pdf to your licenses.licx file:
C1.C1Pdf.C1PdfDocument, C1.C1Pdf.4
You can also use the LicxGenerator to generate a licenses.licx file for your application. You can learn more about the same using the below mentioned blog post:
https://www.grapecity.com/en/blogs/licensing-and-licenses-licx-file-licxgenerator-tool/
If this does not solve your problem, I request you to share the below mentioned details:
Best Regards,
Esha
