How Can I Center a Custom Auto Sized Window

[Kori]

So, here's my scenario - in our app, the content of the window can very likely change, so what I've done is added the following to the pages being opened:

function pageLoad() { fixWindow(); }

function fixWindow() {
  // Fix the height to show the buttons in the right place.
  var oWnd = GetRadWindow();
  var contentHeight = $('#mainContent').height();
  var newHeight = contentHeight + 10;
  var windowWidth = oWnd.get_width();
  $('#popupWrapper').height(newHeight);
  $('#popupWrapper').width(windowWidth - 75);
  var windowHeight = newHeight + 105;
  oWnd.set_height(windowHeight + "px");
  // if (oWnd != null) {
      // oWnd.center();
  // }
}

This works great, except that if I then try to center the window every time, the window will remain open after a postback. How can I correct this so that the window gets centred and works normally?

(Side note: We tried using the auto-size, but it never did a great job of keeping the window sized properly).

Thanks,
Kori

Hello Kori,

Take a look at the following help article which explains the most common reasons for problems with autosizing:  http://www.telerik.com/help/aspnet-ajax/radwindow-troubleshooting-autosize-not-correct.html. See which of the points apply to your case and try employing the suggestions.

As for the behavior you get after calling center() - how are you calling the  fixWindow() function? Is it only on the initial page load, or also after AJAX requests? I have seen similar behavior when center or moveTo() have been called after a postback but the RadWindow is already closed on the client (e.g. via the [x] button). If this is your case you can try adding a check - if(oWnd.isVisible()) oWnd.center();

I tried your code in a simple page and things seem to be working fine with me: http://screencast.com/t/sgpws5Un. I am also attaching my test page here as a reference. Please examine it and see what is the difference in the setup that is causing the problem on your end.
