Table row not updating correctly using MVC Ajax - asp.net-mvc

Question

I have a table with each row as an ascx. This control consists of a Ajax form which includes cells which might have inputs. Here is the ascx:
<%# Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<NerdDinner.Models.Dinner>" %>
<% using (Ajax.BeginForm("ViewAll", new AjaxOptions
{UpdateTargetId = "Dinner" + Model.DinnerID, InsertionMode = InsertionMode.InsertAfter, OnSuccess = "jsfunction"
})) {%>
<%= Html.Hidden("ID", Model.DinnerID)%>
<td><input type="submit" value="Save" /></td>
<td><strong>'<%=Model.Title%>'</strong></td>
<td><%=Model.EventDate.ToShortTimeString()%> on <%=Model.EventDate.ToShortDateString()%></td>
<td><%=Model.Address%></td>
<td><%= Html.TextBox("HostedBy", Model.HostedBy)%></td>
<td><%= Html.ActionLink("Edit", "Edit", new { id = Model.DinnerID })%></td>
<%} %>
After a submit, I complete my processing and send back the updated ascx to replace the existing one.
However this ascx gets constructed a little different than the original which causes it to render incorrectly
This is what the original ascx looks like in FF:
<tr id="Dinner5">
<form onsubmit="Sys.Mvc.AsyncForm.handleSubmit(this, new Sys.UI.DomEvent(event), { insertionMode: Sys.Mvc.InsertionMode.insertAfter, updateTargetId: 'Dinner5', onSuccess: Function.createDelegate(this, jsfunction) });" method="post" action="/NerdDinner/Dinners/ViewAll"/>
<input id="ID" type="hidden" value="5" name="ID"/>
<td>
</td>
<td>
</td>
<td>12:00 AM on 2/2/2010</td>
<td>ZSA2</td>
<td>
</td>
<td>
</td>
</tr>
This is what the returned control (ajaxContext.get_data()) looks like:
<tr id="Dinner1">
<form onsubmit="Sys.Mvc.AsyncForm.handleSubmit(this, new Sys.UI.DomEvent(event), { insertionMode: Sys.Mvc.InsertionMode.replace, updateTargetId: 'Dinner1' });" method="post" action="/NerdDinner/Dinners/ViewAll">
<input id="ID" type="hidden" value="1" name="ID"/>
<td>
</td>
<td>
</td>
<td>12:00 AM on 1/1/2010</td>
<td>ZSA1</td>
<td class="red-back">
</td>
<td>
</td>
</form>
</tr>
Notice the latter does not contain any tds directly under tr but the form encloses all tds and so nothing is rendered.
In IE, I get an error saying 'htmlfile: Unknown runtime error' in MicrosoftAjax.js.
I'm sure I'm missing something basic here. Any help would be appreciated. Thanks.

A few things. This code from your original snippet doesn't look quite right as the input is outside of the form. If you notice the end of the form tag is self closing in this case.
<form onsubmit="Sys.Mvc.AsyncForm.handleSubmit(this, new Sys.UI.DomEvent(event), { insertionMode: Sys.Mvc.InsertionMode.insertAfter, updateTargetId: 'Dinner5', onSuccess: Function.createDelegate(this, jsfunction) });" method="post" action="/NerdDinner/Dinners/ViewAll"/>
<input id="ID" type="hidden" value="5" name="ID"/>
In your code below it appears as though you're explicitly telling the form to encapsulate all of the td's, note the positioning of the curly braces for the BeginForm method.
<% using (Ajax.BeginForm("ViewAll", new AjaxOptions
{UpdateTargetId = "Dinner" + Model.DinnerID, InsertionMode = InsertionMode.InsertAfter, OnSuccess = "jsfunction"
})) {%>
<%= Html.Hidden("ID", Model.DinnerID)%>
<td><input type="submit" value="Save" /></td>
<td><strong>'<%=Model.Title%>'</strong></td>
<td><%=Model.EventDate.ToShortTimeString()%> on <%=Model.EventDate.ToShortDateString()%></td>
<td><%=Model.Address%></td>
<td><%= Html.TextBox("HostedBy", Model.HostedBy)%></td>
<td><%= Html.ActionLink("Edit", "Edit", new { id = Model.DinnerID })%></td>
<%} %>
I'm not quite sure what you're trying to accomplish but hopefully this gets you started in the right direction.
How about using a nested table? This should help it in Firefox.
<td>
<% using (Ajax.BeginForm("ViewAll", new AjaxOptions
{UpdateTargetId = "Dinner" + Model.DinnerID, InsertionMode = InsertionMode.InsertAfter, OnSuccess = "jsfunction"
})) {%>
<%= Html.Hidden("ID", Model.DinnerID)%>
<table><tr>
<td><input type="submit" value="Save" /></td>
<td><strong>'<%=Model.Title%>'</strong></td>
<td><%=Model.EventDate.ToShortTimeString()%> on <%=Model.EventDate.ToShortDateString()%></td>
<td><%=Model.Address%></td>
<td><%= Html.TextBox("HostedBy", Model.HostedBy)%></td>
<td><%= Html.ActionLink("Edit", "Edit", new { id = Model.DinnerID })%></td>
</tr>
</table>
<%} %>
</td>

Interesting- i ran into this EXACT problem just a few minutes ago.
Apparently, IE8 does not like to update elements, only divs.
this blog post got me on the right path, and i just used a div as my updatetargetid rather than the i was originally using. it's ugly now, but at least it works. i need to figure out how to make it look a little nicer.
hope this helps some!
