AjaxDropDown Parent property inside EditorTemplate

Title:

BI{code} ?

Hello, How could I set the "parent" property in a AjaxDropDown for correctly identifying her father in a EditorTemplate? In a view of creating a vehicle I have the following form @using ( Html.BeginForm ("Create", "Vehicles" ) ) {   @Html.EditorFor (m = > m.VehicleEditor ) } Inside VehicleEditor.cshtml I have two AjaxDropDown  1. @ ( Html.Awe (). AjaxDropdownFor (m = > m.MakeId )  2. @ ( Html.Awe (). AjaxDropdownFor (m = > m.ModelId .) Parent (m = > m.MakeId ) The Id (1) is VehicleEditor.MakeId , however the "Parent " property set is simply " makeId " thus rendering the javascript is: " ... data : {" keys " : [ " parent "]," waltz " : [" MakeId "] } ... " and should be " ... data : {" keys " : [ " parent "]," waltz " : [" VehicleEditor_MakeId "] } ... " To fix it I have the following option, but consider it a bad practice because any change in location or model would force me to change the view :  @ ( Html.Awe (). AjaxDropdownFor (m = > m.ModelId .) Parent ( " VehicleEditor.MakeId " ) The same thing happens if the parent adds the " Sufix " property. It is possible to do different? thanks

  thank you for the demo please change this line in MealEditor.cshtml @(Html.Awe().AjaxDropdownFor(m => m.Meal).Url(Url.Action("GetItems", "MealAjaxDropdown")).Parent(Html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName("Category"))) for the moment, after the next release your initial code will work as well or you can use this helper to get the name: public static class Helpers { public static string GetName<T, TReturn>(this HtmlHelper<T> h, Expression<Func<T, TReturn>> expression) { return h.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(ExpressionHelper.GetExpressionText(expression)); } } and use it like this: .Parent(Html.GetName(o => o.Category))

  I created a "Helper" to show the category name dynamically:  public static string GetPropertyName <TObject> (Expression <Func <TObject, objects>> exp)          {              if (exp.Body is MemberExpression)              {                  return ((MemberExpression)exp.Body).Member.Name;              }                         var op = ((UnaryExpression) exp.Body).Operand;             return ((MemberExpression) op).Member.Name;          } Used: Helper.GetPropertyName <ModelEditor> (m => m.Category) All together: @(Html.Awe().AjaxDropdownFor(m => m.Meal).Parent(Html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(Helper.GetPropertyName<MealEditor>(m=>m.Category))) Thanks!
