我想建一个空Dropdownlistfor到接收到前Dropdownlisfor选择的结果:
实际的观点:
<div id="makes">
@Html.DropDownListFor(m => m.Make_Id, Model.MakeList, HeelpResources.DropdownlistMakeFirstRecord)
</div>
<div id="models">
@Html.DropDownListFor(m => m.Model_Id, Model.ModelList, HeelpResources.DropdownlistModelFirstRecord)
</div>
实际控制人(工作,我必须建立一个空SelectedList但我觉得奇怪,不得不这样做):
public virtual ActionResult Create()
{
// Build the Dropdownlist for the Makes
var makesDto = _makeService.ListAllMakes();
var makesViewModel = Mapper.Map<IList<MakeDto>, IList<MakeViewModel>>(makesDto);
// Build the Dropdownlist for the Models
var makeId = -1;
var modelsDto = _modelService.ListModelByMake(makeId);
var modelsViewModel = Mapper.Map<IList<ModelDto>, IList<ModelViewModel>>(modelsDto);
// Build the ViewModel to return to the View
CreateAdViewModel viewModel = new CreateAdViewModel();
viewModel.MakeList = new SelectList(makesViewModel, "ID", "Name");
viewModel.ModelList = new SelectList(modelsViewModel, "ID", "Name");
return View(viewModel);
}
有没有建立像这样的方式:@ Html.DropDownListFor(M => m.Model_Id,空)
并取出//构建DROPDOWNLIST从控制器的型号?
谢谢
