[Solved] Telerik MVC Window Redirects to HttpResult Action on Submit in IE8

[Jenna Guess]

I am using a Telerik Window to display a custom Edit Form for a Telerik Grid.  The Telerik Window is in a form tag:

@using (Html.BeginForm("TestingAccommodationsEditPost", "TestingAccommodations", FormMethod.Post, new { id = "TestingAccommodationsEditForm" }))

and I have a submit button:

<button type="submit" class="t-button t-grid-insert">Save</button>

The submit JS is:

<script type="text/javascript">
    $('#TestingAccommodationsEditForm').submit(function (e) {
        if (!window._504.AccommodationPlan.TestingAccommodations.IsFormValid()) {
            return false;
        }
        else {
            var data = $(this).serialize();
            $.post(this.action, data, function () {
                $('#TestingAccommodationsEditForm').closest('.t-window').data('tWindow').close();
                $("#TestingAccommodations").data("tGrid").ajaxRequest();
            });
            e.preventDefault();
            return true;
        }
    });

</script>

The controller action is an EmptyResult with the following signature:

[HttpPost]
public EmptyResult TestingAccommodationsEditPost(TestingAccommodationsEditModel model)

The issue is that when I'm in IE8, submitting the Telerik Window results in the data being saved and a redirect to: http://localhost:19623/_504/TestingAccommodations/TestingAccommodationsEditPost.  It shouldn't do anything but save the data and close the Window.  Also if I watch IE Developer Tools, submitting the Telerik Window changes the Document Mode to 'Quirks'.

In IE9 it works correctly, on submit the Telerik Window closes so i can continue to interact with the page I was on.  Attached is the complete code related to this issue.  Can anyone advise on how to resolve this issue so that it works on IE8 just as well as it works in IE9?  We are using version 2011.2.712 of the Telerik MVC tools with MVC4.  Thank you.

Hello Jenna,

The code looks correct and I could not reproduce the described behavior on my side. The problem could be caused by the script used inside the Window's content, since it will be added twice to the page. Could you check if binding to the submit event from outside the Window resolves it?
If the problem persists, a sample project which replicates this behavior would help to determine what exactly is going wrong.
