How to Open the dialog pop up in my Controller code

I have this div in my master page.

 <div id="UICancelChanges" title="Are you sure?" style="display: none;">
     开发者_StackOverflow       Your changes have not been saved. Are you sure you want to CANCEL ?
        </div>   

On click I am just opening Jquery dialog popup window..

CancelEdit = function (accountId) {
            $("#UICancelChanges").dialog({
                resizable: true,
                height: 140,
                width: 500,
                modal: true,
                buttons: {
                    "Yes": function () {
                        $(this).dialog("close");
                    },
                    "No": function () {
                        $(this).dialog("close");
                    }
                }
            });
            return false;
        };

Is there any way that I can change the Title of this Div popup dynamically? using same code I need to change the title dynamically?

How to open my popup window in the controller code?something like this?

  return new JavaScriptResult() { Script = "alert('SubCategory Successfully Added. Thank You.'); window.location='/ObnCategory/Index';" };

Instead of alert i need to open the popup window.

Thanks

call this before you display the dialog

initialise:

$( "#UICancelChanges" ).dialog({ title: 'Dialog Title' });

to set the new title do

$( "#UICancelChanges" ).dialog( "option", "title", 'New Dialog Title' );

to get the title

var title = $( "#UICancelChanges" ).dialog( "option", "title" );

for more help on the properties visit http://jqueryui.com/demos/dialog/#option-title

Per the jQuery UI website documentation:

$( ".selector" ).dialog( "option", "title", 'Dialog Title' );

you can use this:

$("span.ui-dialog-title").text(anything);
