Hello,

Is there a way to lock Excel or PDF reports generated by Telerik component?
I need to prevent users to be able to modify the reports once generated.
Thanks for your answer.
Regards

Joël

Hi,

Security features such as locked editing, password-protection and/or encryption are currently not supported in the PDF file generated by Telerik Reporting (in fact not supported in any of the available formats). Such advancements are logged in our system for future implementation.

Sorry for the temporary inconvenience.

You say it is not possible for PDF. What about Excel reports?

Hello Joël,

As noted in my previous post such features are in fact not supported in any of the available formats.

Hello,

Always on our need of locking Excel worksheets. we intend to use Telerik ASPNET viewer to display a preview of our reports. Do you think it will be possible to intercept output of Telerik Report to modify dynamically generated Excel reports using an HttpModule for example ?
Thanks for your answer

Hi,

Is locking of pdf reports from being edited still not possible?  I have a client who's discovered that pdfs they generate and send out are subsequently being tampered with, so I really need to be able to prevent this from being possible.

Thanks,

Mike

No it is not possible. But if you know how to lock PDF using tiers components, it should be possible to lock it on the fly just after Telerik.

Hi,

There is no such feature in Telerik Reporting yet. Our aim is to produce a report document in the selected rendering format, with layout as close as possible to the one in the viewer and considered with the media. Further modifications over the rendered documents can be achieved through third party tools and libraries for document processing.

Hello Damian,

The PDF security settings can be applied through the deviceInfo parameters passed to the reportProcessor.Renderreport method - Password ProtectionIn order to enable PDF password protection in code you have to set the device info as shown in the following code snippet:
System.Collections.Hashtable deviceInfo = new System.Collections.Hashtable();
deviceInfo["OwnerPassword"] = "test";
deviceInfo["UserPassword"] = "test1";
 
For more information on the settings see: PDF Device Information Settings help article.

Silviya

Password protecting this export format is currently not supported out of the box, however, we do have a feature request about this functionality and I have cast your vote for it in order to increase its priority - Introduce optional password protection for Office formats (telerik.com).

With that being said, there are a couple of workarounds that you may implement in order to achieve this, they are listed in my colleague Neli's answer to the link that I posted above
