如何从服务器端调用Ajax.BeginForm的OnFailure事件？

Question

当服务器端发生错误时，如何调用Ajax.BeginForm的OnFailure事件？
我应该处理OnComplete函数的错误吗？

查看

<script type="text/javascript">

function PullIntoTable(e) {
・・・・・
}

function search_start() {
....
}

function Failure() {
        alert("Called!!");
}

.........
</script>

@using (Ajax.BeginForm("Search", "SearchCompanyJP",
                       new AjaxOptions { HttpMethod = "POST", OnBegin = "search_start", OnSuccess = "PullIntoTable", OnFailure = "Failure", OnComplete = "search_close" }))
{
    <div>
        <span class="label">Company</span>
        @Html.TextBoxFor(m => m.CompanyName, new { @class = "textbox" })
    </div>
    <div>
        <span class="label">Address</span>
        @Html.TextBoxFor(m => m.Address, new { @class = "textbox" })
    </div>

    <input type="submit" value="Search"  />
}

XXXService.cs - 由控制器调用

Insertable = false;
if (Insertable)
{
・・・・・
}
else
{
    throw new CustomException(action, message);
}

Global.asax ---由于ajax，此重定向不起作用。这就是我实现失败功能的原因。

void Application_Error(Object sender, EventArgs e)
{
    var exception = Server.GetLastError();
    Server.ClearError();
    Response.Redirect("/Error", false);
}
