在asp.net mvc3中如何在回发后保持下拉列表选中项目.
解决方法
做这样的事情：
- [HttpPost]
- public ActionResult Create(FormCollection collection)
- { if (TryUpdateModel(yourmodel))
- { //your logic
- return RedirectToAction("Index");
- }
- int selectedvalue = Convert.ToInt32(collection["selectedValue"]);
- ViewData["dropdownlist"] = new SelectList(getAllEvents.ToList(),"EventID","Name",selectedvalue);// your dropdownlist
- return View();
- }
并在视图中：
- <%: Html.DropDownListFor(model => model.ProductID,(SelectList)ViewData["dropdownlist"])%>
