Question

I am having an ajax call with is working fine in Mozilla and Chrome, but not in IE 9.0. The code is as follows:

I am not able to understand why is the myDiv not being refreshed. The save is done accordingly and it is just that the myDiv isn`t being refreshed in IE9.0.

$.ajax({

                cache: false,
                contentType: "application/json; charset=utf-8",
                dataType: "html",
                url: "@Url.Action("Save", "Employee")",
                data:
                {
                    Id: $("#ID").val(),

                },
                success: function (data)
                {
                        $("#myDiv").html(data);                


                },
                error: function (request, status, error)
                { 
                                    }
           });

<div id="myDiv">
            @{Html.RenderPartial("NewPage", Model);}
        </div>

---

NewPage.cshtml

    @model MvcUI.Models.myModel
<div id="GridDiv">
<table>

</table>
</div>

Controller:

   [Authorize]
    public ActionResult NewPage( int Id)
    {
           return PartialView(new myModel(Id));
    }

    [Authorize]
    public ActionResult Save(int Id)
    {

        myModel.Save(Id);
        return RedirectToAction("NewPage", new {Id = Id});

    }

observation
I have been doing various tests and observed the following behaviours:
In debug mode:
1. First time I do save, save done and table refreshed.
2. second time, the save done and table refreshed.
3. When I do it for the 4th time, the save done, but doesnt reach ActionResult NewPage( int Id), table doesn`t refreshed but some old data displayed…!

In deployed mode:
1. Only First time I do save, save done and table refreshed.
2. Second time, it only saves but does not refresh table data!

I don`t have any error or exception.

Have you tried setting the response-expiry headers? I have had issues where IE did not appear to reload the page when you do not set the following:

<% Response.CacheControl = "no-cache" %>
<% Response.AddHeader "Pragma", "no-cache" %>
<% Response.Expires = -1 %>

I’ve put them in ASP tags, but feel free to do this in your controller if you prefer (rather than repeat it in every action, possibly create an initialisation method)

EDIT:

As per @learning’s comment, one can also use the OutputCache attribute to do effectively the same thing

[OutputCache(Duration = 0)]
