+
+## Description
+
+There could be a requirement to disable the default ContextMenu in the RadPdfViewer control. 
+
+## Solution
+
+To disable the right-click context menu in PdfViewer for UI for WinForms, set the `RadContextMenu` property to `null`. This removes the context menu entirely, preventing it from appearing when the user right-clicks inside the RadPdfViewer.
+
+### Example Code
+
+````C#
+
+this.radPdfViewer1.RadContextMenu = null;
+
+````
+In some cases, the default menu items need to be modified, and the [RadPdfViewer Context Menu]({%slug winforms/pdfviewer/ui/context-menu%}) article demonstrates how to do that.
