I am using ASP.NET MVC with jquery. I have the following MVC Action that returns a partial page on Success. On Application Error, I am not sure what to send it for correctly handling it at the client side.

public ActionResult LoadFilterSet(int filterSetId)
        {
            try
            {
                BreadCrumbManager bcManager = this.ResetBreadCrumbManager(this.BreadCrumbManagerID);
                GeneralHelper.LoadBreadCrumbManager(bcManager, filterSetId);

                ViewData["BreadCrumbManager"] = bcManager;

                return View("LoadFilterSet");
            }
            catch (Exception ex)
            {
                return Content("");
            }
        }

Following is my jquery ajax call. Notice that I am checking for the data length to make sure there are no errors. Please suggest me a better way of doing this.

$.ajax({
            type: "GET",
            dataType: "html",
            async: true,
            data: ({ filterSetId: selectedId }),
            url: link,
            contentType: "text/html; charset=utf-8",

            success: function(data, textStatus) {
                if (data.length > 0) {

                    // Clear the local filters first.
                    clearLocalFilters();

                    $('td.selected-filters table.filters-display').append(data);
                }
            }

        });
