I have a WinForms application and a form with WebView2 control. I set Source property of the Webview2 control to a local pdf file. When I run the program, the pdfviewer is showing the pdf document, but the draw and highlight controls are not showing.
When I open the pdf in edge browser, the controls are showing. Where am I doing the mistake.
The feature to annotate PDFs is disabled in WebView2. You can read more about this on Disabling Feature: PDF Annotations Support.
Additionally, you can open a feature request to enable this feature on the WebView2 Feedback repo.
