How to make jQuery dialog modal?

Question

I am using jQuery dialog in asp.net. It is working fine for me. The problem is when I open the dialog box, I can still work parent page functionality. I don't want that. Just dialog to modal and should not allow focus on parent page.

window.onload = function onloadFunction() {

        //setup edit person dialog
     $('#uploadPic').dialog({
             autoOpen: false,
             draggable: true,
             title: "Upload Picture",
             open: function(type, data) {
                 $(this).parent().appendTo("form");
             }
         });
     }

Is there any way to make it modal? Or if lost focus on dialog box close it automatically?

Please help me out.

Answer 1

Use

$('#uploadPic').dialog({
         autoOpen: false,
         modal: true,
         draggable: true,
         title: "Upload Picture",
         open: function(type, data) {
             $(this).parent().appendTo("form");
         }
     });
 }

I have just added the modal option to your sample.
