Hi, Jalil -
While you should wait to receive a response to this question from Appeon, I will be surprised if there is a way to do this. I often see questions of a similar nature asked by people in this Q&A forum.
It's fairly evident that the PB web browser control does not currently provide access to all of the public methods, properties and all of the events supported by the WebView browser "engine". I wish it did, then all PB developers could access all of the browser features they require to accomplish their objective(s). I do not know why these limitations exist in an ever-increasingly important component such as the PB web browser control. When it comes to programmable access to browser functionality, I feel that the best limitations are to have NO limitations.
Best regards, John
