  Hi, here's a working example:

  var wv = Ti.UI.createWebView({
      url:'http://developer.appcelerator.com/questionsdfd/130976'
  });
  
  var xhr = Ti.Network.createHTTPClient();
      xhr.onload = foo;
      xhr.open('GET', 'http://developer.appcelerator.com/questionsdfd/130976');
      xhr.send();
  
  var win = Ti.UI.createWindow({ title:'Tab 1', backgroundColor:'#fff' });
  win.add(wv);
  win.open();
  
  function foo() {
      if (this.status == 404) {
          alert('Got 404 error - WebView will be hidden.');
          wv.hide();
      }
  };
  

• You could use an HTTPclient call to check for the existence of the page before displaying the web view. You are looking for the status value specifically.

• Can you give me a working example please im struggling.

• you could listen the webview load event and look the webview.html property for "Error 404" string on title. Not 100% valid, but can do the job in most cases.

• I figured a workaround but thanks for all your help

• Essentially i wanted to use this method to point to a page that tells you if the app is up to date so instead of using titanium i did it via the website. Implementing page redirect code which i can switch off and thus the page that shows the update message will be displayed. So not used titanium at all but i have managed to get exactly what i wanted.
