Question

I have this method in the controller

[HttpDelete]
public void DeleteDocument(int id)
{
   //Here I do the deletion in the db
}

In the view I have this, calling a method that returns a partial view

@{ Html.RenderAction("GetDocumentsByMember"); }

The GetDocumentsByMember method

    public ActionResult GetDocumentsByMember()
    {
        var companyGuid = HttpContextHelper.GetUserCompanyGuid();

        var documents = _service.GetUploadedDocumentsByMember(companyGuid);

        return PartialView(documents);
    }

And the partial view

@model IEnumerable<GradientCapital.DomainModel.Entity.Document.Document>
<div id="uploadeddocuments">
    @*Here there's a table and at one of the columns there's the next link*@

    <td id="delete">
        @Ajax.ActionLink("Delete", "DeleteDocument", new { id = document.Id },
        new AjaxOptions
            {
               Confirm = "Are you sure you want to delete?",
               HttpMethod = "DELETE",
               OnComplete = "deleteComplete"
            })
    </td>
</div>

And deleteComplete just refresh everything

<script type="text/javascript">
    function deleteComplete() {
        window.location.reload();
    }
</script>

Quite long (is correctly formatted?) code for a simple question, I can’t make the ajaxoption UpdateTargetId work here instead of having to call this deleteComplete function. Any idea?

Thanks

Instead of reloading the entire page you could call the GetDocumentsByMember action using AJAX and update only the portion of the DOM that has actually changed:

<script type="text/javascript">
    function deleteComplete() {
        $.ajax({
            url: '@Url.Action("GetDocumentsByMember")',
            type: 'GET',
            cache: false,
            success: function(result) {
                $('#uploadeddocuments').html(result);
            }
        });
    }
</script>

Also you’d better use OnSuccess = "deleteSuccess" instead of OnComplete = "deleteComplete" because you should update only if the Delete call actually succeeded. Don’t forget that the OnComplete callback is always invoked, no matter whether the AJAX call succeeded or not.
