Hide or disable the Toolbar Button

5 Sep 20251 minute to read

In the WinForms PDF Viewer, there is an API called ToolbarSettings that allows you to access and manage toolbar buttons. To hide a specific button, use the IsVisible property associated with that button. By setting IsVisible to false, the button will be hidden from the toolbar.

The following code snippet demonstrates how to hide the Open and Save buttons in the WinForms PDF Viewer control.

//Load the document ot PDFViewer control
 pdfviewerControl.Load("Input.pdf");
 
//Change the visibility of open and save button
pdfviewerControl.ToolbarSettings.OpenButton.IsVisible = false;
pdfviewerControl.ToolbarSettings.SaveButton.IsVisible = false;
' Load the document into the PDFViewer control
pdfviewerControl.Load("Input.pdf")

' Change the visibility of Open and Save buttons
pdfviewerControl.ToolbarSettings.OpenButton.IsVisible = False
pdfviewerControl.ToolbarSettings.SaveButton.IsVisible = False

The following is the image of a PDF document which hides the Open and Save button in Toolbar.
