blockUI works but unBlockUI Isn't

Question

I've implemented block UI as this request can take a little, time when the ajax request starts everything works as expected.

But when the ajax request finishes and the msgbox is shown, the UI doesn't unblock!

Any ideas?

I'm using IE8.

$().ajaxStart($.blockUI); 
$().ajaxStop($.unblockUI); 

function ChangeCompanyState(companyId, state) {
    var parameters = "{companyId:" + companyId + ",state:\"" + state + "\"}";
    $.ajax({
        type: "POST",
        url: "Ajax/AjaxFragments.aspx/ChangeCompanyState",
        data: parameters,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(msg) {
            if (msg.d.length > 1) {
                alert(msg.d);
                $.unblockUI();
            }
            else {
                //Theres no message to process success.
                window.location.reload();
            }
        }

    });
}

Answer 1

As told here, using

<meta http-equiv="X-UA-Compatible" content="IE=7" />

seems to fix the problem. I didn't get any other way to solve it in my own project.

Answer 2

$.unblockUI(); $(".blockUI").fadeOut("slow");

Answer 3

i think if ur message is in another page or in a iframe content it will be removed after unblockUI....so try setting the message within the same page to avoid this

Answer 4

I had the same, and resolved by using parentesis in unbluckUI sentence.

// block when ajax activity starts
function beginRequestHandler(sender, args) {
    $.blockUI({ message: '<h1><img src="loading.gif" /> Just a moment...</h1>' });
}

// unblock when ajax activity stops 
function endRequestHandler(sender, args) {
    $.unblockUI(); // previously was $.unblockUI;
}
