Hi Domenico,
Thank you for using Syncfusion products.
At present we do not have the support for enabling or disabling toolbar buttons in the built-in toolbar of PdfViewerControl in windows forms. However we can achieve this by using Custom Toolbar sample and we have also created a simple sample to disable Open and Save button and it can be downloaded from the following location.
