UI Customization

You can design and use your UI for interacting with PDF files using the PdfDocumentView control. This control is exclusive for customization purposes, and it supports only viewing PDF files without any other built-in UIs. We have exposed equivalent APIs for all the functionalities, and you can bind them to your custom UI to make use of all the features. Refer to our API reference for more details.

Toolbar customization

You can create and customize your toolbar by disabling the default toolbar in the PdfViewerControl. For additional information on how to adjust the toolbar’s visibility, please refer to this documentation.

Appearance customization

As it inherits from System.Windows.Forms.Form, you can change the appearance of the control to fit the look and feel of your application. You can customize the appearance either by creating your control template or by choosing any of the Syncfusion-supported built-in themes that are available in the Syncfusion.Shared.Base assembly.
