Disabling toolbar buttons in PdfViewerControl

I am currently evaluating the PDFViewer control for WinForms, and have found it to be ideal for embedding into our application, because we want to present to the user a PDF document for review.  However, the DocumentToolbar also has a button (btnOpenFile) to load any arbitrary PDF file.  All buttons on the toolbar are okay for our application's review window; it's just the non-public btnOpenFile button that defeats the purpose of loading one specific PDF file.  Is there any way to hide this button?

Hi Bruce,

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 Meikandan.

Thanks for your reply.

I was looking for a way to reuse the available toolbar and disable or hide just one button.  I like the 11 functions on the built-in toolbar; it's just the one "Open document" button that I don't want.

Any chance the toolbar properties (and those of the contained controls) can be publicly exposed for developers to customize, as opposed to having to redesign and recode everything?

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.

I had the same problem.  Had to use a hack to fix it, but it works for now, until they expose it in a later version.  This code will hide the Open PDF button and the separator that follows it:

DirectCast(pdfControl.Controls(0).Controls(0).Controls(0), ToolStrip).Items(0).Visible = False
DirectCast(pdfControl.Controls(0).Controls(0).Controls(0), ToolStrip).Items(1).Visible = False

Hi Dib,

Thank you for your update.
The feature "Hiding the ‘Open Document icon’ in the PdfViewer Control’s built in tool bar"  is still not implemented and we will let you know once the feature is implemented.

Please let us know if you have any other questions.

I too need this feature. The posibility to hide the "Open Document" button in the toolbar but keep all the others. Do you have any plans of escalating this issue? Since it has been 3 years since it first was suggested.

In the meantime: Is there a way to work around this without recreating the entire toolbar?

Hi Håkon, 
At present we do not have support to disable the open button from the inbuilt toolbar of PdfViewerControl. We have logged a feature request for the implementation of the same. 
We will implement this feature in any of our upcoming releases. We usually have an interval of at least three months between releases. The feature implementation would also greatly depend on the factors such as product design, code compatibility and complexity.  
However we have created a workaround to achieve the same using custom toolbar sample and it can be downloaded from the below link. 
Note: The workaround provided above will not have any changes in the inbuilt toolbar of PdfViewerControl. 
We will let you know once the feature is implemented.

I have reviewed your sample and found that it cannot supply what we need at the moment.

We consider using your pdf viewer in stead of the one provided by DevExpress because you support more obsolete printer drivers than them, but as long as this would require us to implement the toolbar manualy, your control is not an option.
I suggest including a standalone toolbar for the pdf viewer where we are able to hide any specific button like the one provided by DevExpress (xtrapdfviewer.bars.pdfcommandbar).

I would expect that most programs will find the "Open" button irrelevant, except for dedicated PDF-engines.

Until this is fixed, your viewer will not be an option to us.

Also: Exposing the ToolBar and its button through the PdfViewerControl would be a great solution!

pdfViewerControl1.ToolbarSettings.OpenButton.IsVisible = false;
