DotNetNuke, Ajax and jQuery: Hiding a table row

I have written a DotNetNuke module for a customer that allows them to "delete" a coupon from a table. When they click the link, an Ajax POST is created, using jQuery, and upon success the row should be deleted (or at the very least, hidden) and a success message displayed with a CssClass attached. Everything is working just fine, minus the part where the row is deleted. I have not had this problem in any other ASP.NET Web Forms/MVC project, just DotNetNuke. What winds up happening is my entire table is deleted and the success message is displayed. Here is my code:

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

jQuery.noConflict();
var deletingCouponID = null;

function DeleteCoupon(_CouponID) {

    deletingCouponID = _CouponID;

    jQuery.post(
        "mylink.aspx",
        { CouponID: _CouponID },
        function (data) {

            if (data.Response == "Success") {
                alert("#row" + deletingCouponID);

                jQuery("#tblCoupons tbody tr.row" + deletingCouponID).remove();
                jQuery("#divAjaxMsg").html("<p>" + data.Message + "</p>");
                jQuery("#divAjaxMsg").addClass("NormalRed");
            }
            else {
                jQuery("#divAjaxMsg").html("<p>" + data.Message + "</p>");
                jQuery("#divAjaxMsg").addClass("NormalRed");
            }
        },
        "json"
    );
}

and the HTML:

<div style="padding:1px">

<asp:Label runat="server" ID="lblMessage" ></asp:Label>

<div runat="server" id="divCouponList" >

    <div style="text-align: center">
        <h1>Coupon List</h1>
    </div>

    <div id="divAjaxMsg" />

    <table cellpadding="5px" id="tblCoupons">
        <thead>
            <tr>
                <th>Coupon ID</th>

                    </tr>
        <%
                }

                if (Count < 1)
                {
        %>
                    <tr>
                        <td colspan="10" style="text-align: center;">No coupons found</td>
                    </tr>
        <%
                }
            }
        %>
        </tbody>
    </table>
    <p>
        <a href="<%= NewEditURL %>">Create New Coupon</a>
    </p>
</div>

I am sure it is something silly that I am missing (or screwing up) so I thought another few sets of eyes on it might help. I do not really like writing DNN modules, so that doesn't help much! Thanks in advance!

Edit 2: Thank you everybody for your help and ideas! I appreciate everybody's time and effort in helping me with this.

Edit: Here is the "before and after" markup from IE. The row is not actually getting deleted. I could live with the row just being hidden so the user can't click the edit/delete button: <confused />

<table cellpadding="5px" id="tblCoupons">
        <thead>
            <tr>

                <th>Date Created</th>
                <th>Expiration Date</th>
                <th>Amount</th>
                <th>Min Purchase Amount</th>
                <th>Num Uses</th>
                <th>Max Uses</th>

Change

jQuery("#tblCoupons tbody tr.row" + deletingCouponID).remove();

to

jQuery("#row" + deletingCouponID).remove();

Also return false from your function or use event.preventDefault() to stop links from following.

add a header class to your thead and use code bellow

$("#myTable tr:not(.header)").remove();
$("#myTable").append(table);

Are you sure the coupon id is being set correctly? It would make sense if it wasn't because your code uses that id as part of the criteria of what to delete. If it wasn't present then it would basically be telling the table to delete all the rows. Below is basically what it would look like if it wasn't set.

jQuery("#tblCoupons tbody tr.row").remove();

Which would delete all rows in your tbody.

Can you use firebug or some other dynamic source generator to look at the page source after the function is run and see if the whole table has been deleted or just all the rows?

p.s. I have written a lot of DNN modules and seems hard to believe that this would be related to DNN itself vs just some oversight. Though I'm not saying impossible.
