Hello, first of all thank you for this useful component.
I was using TWebBrowser in my project and I could reach an element on the page with its Id and change its content (GetElementbyId).
How can I do this with WebView4Delphi?
Thanks

Hi,
As far as I know, WebView2 doesn't expose any API method to access the DOM directly.
However, you can execute some custom JavaScript code that searches for that element and sends the information you need to the Delphi application with a message.
See the BrowserHostAppCommunication demo for all the details about sending messages between the browser and Delphi.
