Hi,

I want to disable the window browser close(X) while I am opening my ModalDialog box, which is small in size and contains buttons for OK and Close.

When the user clicks the 'Close' button the child page should be closed. It should not get closed while they are clicking browser close button.

XML

<script language="javascript" type="text/javascript">

        function Onclick()
        {


        RetVal = window.showModalDialog("CabinMappingChild.aspx","CabinMapping","dialogHeight: 190px; dialogWidth: 550px; titlebar: no; toolbar: no; statusbar:no");
        }
 </script>

I am using the above code but still I could not get it to work.

Can anyone please help me?

You are not allowed to disable the close button in the browser for security reasons.

However... You can open the window in fullscreen size which means the browser automatically will hide the titlebar and the minimize, maximize, and close buttons!

To open a webform in fullscreen see below:

window.open('WebForm2.aspx', '', 'Fullscreen=yes');

Hope that helps!
