Hi,
This has nothing to do with the WebView. It has to do with the TabControl you use. For example, the most rudimentary tab control is just a row of buttons and you then handle the button click event to show/hide whatever you want to show. In your click event you can have code like this:
Code: C#
if (index_of_button_clicked index_of_button_clicked < 3)
webView.Visible = true;
else
webView.Visible = false;
Here the first three tabs shows the WebView and the rest hide it. So the result is the first three tabs shares a single WebView. As you can see, this logic is on the tab control side or in your code. It would not be on the WebView side.
Thanks!
