Model Binding not working with mvc1
We have very large object called FoodFormViewModel. We go to add page like
FoodFormViewModel foodFormViewModel = new FoodFormViewModel();
return View("Edit", foodFormViewModel);
But when we come to post method like
[AcceptVerbs(HttpVerbs.Post)]
[ValidateInput(false)]
public ActionResult Edit(FoodFormViewModel objViewModel)
{
SaveProcess(objViewModel);
return View(objViewModel);
}
Our objViewModel properties are all blank. Our FoodFormViewModel definition is
#region Properties
public MealPlannerDataManager MPManager { get; set; }
public Food Food { get; set; }
public SelectList FoodGroupLevel1 { get; set; }
public SelectList FoodGroupLevel2 { get; set; }
public SelectList FoodGroupLevel3 { get; set; }
public SelectList FoodType { get; set; }

WE couldn't figure out the issue. Any help is highly appreciated. We are using MVC1 with VS 2008

Personally, I think it is very odd to have properties of type SelectList and List<CheckBoxInfo> in your view model class. Most viewmodels should contain properties of very basic types, like string and int. The way you have, makes it very hard to debug & identify your problems but I would go and say that most likely the default model binder doesn't know how to bind values from HTML controls to your viewmodel props.
I would advise looking into building a custom modelbinder or rewriting the view model class. Or rewriting the app as a whole (but I guess that's not an option).
HTH
Certain property name don't match with actual names............need to modify
加载中,请稍侯......
