Thank you for your update,
We can achieve the mentioned scenario with a custom tool bar instead of the tool bar attached with the PdfViewer control. We modified our custom tool bar sample and attached the sample in the below link.
Sample: Custom Toolbar.zip
Please try this sample and let us know if this suits your requirement.
Please let us know if you have any other concerns.
Hi Bruce ,
Thank you for your update.
At present we do not have support for “Hiding the ‘Open Document icon’ in the PdfViewer Control’s built in tool bar”. Could you please report this through Direct Trac Developer Support System (https://www.syncfusion.com/account/login?ReturnUrl=%2fsupport%2fdirecttrac%2fincidents because you can take the advantage of the expertise of a dedicated support engineer and a guaranteed response time and we hope you will take advantage of this system as well. If you have already reported, please ignore this.
Please let us know if you have any other questions.
