Exchanging Html.Action () for an Ajax request

I have a method that returns a ActionResult called through a Html.Action() directly on View using Razor .

This method is used to render a ComboBox of devExpress with the data that I send from a SQL command at the view opening, where it takes a lot of time to load combobox since for every 1 it should go in the bank and bring the data of the past command.

Problem I want to exchange this call through Html.Action() to javascript so that it loads the combobox data in the click event of the component, so I do not lose the loading time of view and load only when the user is actually using / clicking.

View:

@Html.Action("ComboBoxDataFilter", "SearchComboBox", new
        {
          controlName = "ComboBoxFILIAL",
          sql = "SELECT CODFIL, TAG, RAZSOC FROM FILIAL",
          fkField = "CODFIL",
          fields = "TAG, RAZSOC",
          descriptionFields = "Código, Razão Social",
          widthColumns = "30%,70%",
          width = "100%",
          showFormatString = true,
          showAdvancedFilter = false,
          showStandardFilter = false,
          showDropDownButton = true,
          inputHidden = "CODFIL",
          filter = "",
          eventSelectedIndexChanged = "function(s, e) { $('#CODFIL').val(ComboBoxFILIAL.GetValue()); onCodFilChange(); }",
          eventBeginCallback = "",
          filterfield = "RAZSOC",
          value = (Model == null || Model.CODFIL == null) ? 0 : Model.CODFIL
        })

public ActionResult ComboBoxDataFilter(string controlName, string sql, string fkField, string customFkField, string fields, string filter, string eventSelectedIndexChanged, string eventValueChanged, string eventBeginCallback, string eventEndCallback, string value, string sqlValue, string filterfield, string descriptionFields, string fkTable, string compositeFk, string displayFields, string inputHidden, string width, string widthColumns, bool showAdvancedFilter, bool showStandardFilter, bool showDropDownButton, bool showFormatString, string valueType, bool readOnly,  string view, Dictionary<string, object> parametros, bool showCleanButton = true)
{
  var model;
  return PartialView("SearchComboBoxFilter", model);
}

You can do something like this, create an object that receives all settings from your combobox and then sends via post.

             var config ={
                    controlName = "ComboBoxFILIAL",
                      sql = "SELECT CODFIL, TAG, RAZSOC FROM FILIAL",
                      fkField = "CODFIL",
                      fields = "TAG, RAZSOC",
                      descriptionFields = "Código, Razão Social",
                      widthColumns = "30%,70%",
                      width = "100%",
                      showFormatString = true,
                      showAdvancedFilter = false,
                      showStandardFilter = false,
                      showDropDownButton = true,
                      inputHidden = "CODFIL",
                      filter = "",
                    eventBeginCallback = "",
                      filterfield = "RAZSOC",
             }


               $.ajax()({
                    url: "/ComboBoxDataFilter/SearchComboBox",
                    type: "POST",
				    data: config ,
                    dataType: "json"
                });

public ActionResult ComboBoxDataFilter(ComboBoxDataFilter config)
{

  JavaScriptSerializer ser = new JavaScriptSerializer();
  var model = ser.Deserialize<ComboBoxDataFilter>(config);

  return PartialView("SearchComboBoxFilter", model);
}
