Question

Answer 1

+4 A:

You cannot disable F5 (or other browser shortcut keys) via JavaScript.

Setting the WebBrowserShortcutsEnabled property of the WebBrowser control to false should accomplish what you're trying to do.

Got a problem. It disables keyboard shortcuts but also disables links that will open IE.

Handle the `WebBrowser.Navigating` event: `private void WebBrowserNavigating(object sender, WebBrowserNavigatingEventArgs e) { if (e.Url.ToString() != "about:blank") { System.Diagnostics.Process.Start(e.Url.ToString()); e.Cancel=true; } }`

Windows acts weird. Tried pressing F5 continuously then clicking a link but it will not respond to it. But, if you say you put MessageBox onClick event, it will respond to it.

Answer 2

A:

call this function on the onKeyDown event

 document.onkeydown = function(e) {
      // keycode for F5 function
      if (e.keyCode === 116) {
        return false;
      }
      // keycode for backspace
      if (e.keyCode === 8) {
        // try to cancel the backspace
        return false;
      }
    };

This will prevent from F5 reload and backspace back.

This does not work.

josh3736 2010-10-25 02:22:05

it should work now...

Azhar 2010-10-25 02:47:09

this doesn't work. I tried this by injecting in webbrowser. On normal html this will work.
