    Hello Telerik Team,

    we have a strange behavior after changing the ASP.NET AJAX Telerik Version from "2009.3.1103.35" to "2010.1.519.35":
    We have a ASPX page, which opens a new RadWindow in Modal mode. This window is opened via "window.radopen(...)".
    The RadWindow has also get declared a close event handler with "add_close(...)".

    When the RadWindow closes, the calling page opens a new IE window with "window.open(...)" in the close event function and calls  "newWin.focus()" on the new window.  

    The parent page is not reloaded at this point.

    With the previous (old) Telerik Version, the new window was opened as expected and set to the front.

    After updating the Telerik Version, the new window was already opened in the close event handler, but the focus did not get assigned to the new window. It seems, that the parent window is grabbing the focus back. Even with the JS calls:

    Parent Page: self.blur(); newWindow.focus();
    New Window Page: self.focus();

    the new window is moved to the background.

    Do you know of any issues when using the RadWindow in this way in the version as defined above?

    Kind regards,

    Hi Johann,

    I am afraid that I am not familiar with such problem. Could you please open a support ticket and send me a small sample project so I could get a better view over your exact setup?

    All the best,

    Having the same issue here with the Radwindow.  Focus is set back to the calling, parent, window and the window that was open flashes to the foreground then disappears.

    This works fine for me in IE, Chrome and Firefox:
    <telerik:RadWindow ID="RadWindow1" runat="server" OnClientClose="OnClientClose" VisibleOnPageLoad="true">
    <script type="text/javascript">
        function OnClientClose()

    In case the browser window that gets opened loses focus I can suggest a few things:
    - look for custom code that sets focus in the first page. This can be JavaSCript, a partial postback that sets server focus, anything, really
    - add a small timeout around the call to open() and focus() for the browser window to let any other code finish its work before opening the new popup.
