這裏是我的ViewModel,MVC生成DropDownLists動態
公共類FormGroupsAssociationViewModel:BaseViewModel {
public FormGroupsAssociationViewModel()
{
FormTypeFormGroupViewModels = new List<FormTypeFormGroupViewModel>();
}
public FormGroupsAssociationViewModel(IList<FormTypeFormGroupViewModel> formTypeFormGroupViewModels)
{
this.FormTypeFormGroupViewModels = formTypeFormGroupViewModels;
}
public IList<FormTypeFormGroupViewModel> FormTypeFormGroupViewModels { get; set; }
}
公共類FormTypeFormGroupViewModel {
public FormTypeFormGroupViewModel()
{
}
public FormTypeFormGroupViewModel(FormType formType, IEnumerable<FormGroup> formGroups)
{
this.FormTypeId = formType.FormTypeID;
this.Title = formType.Title;
this.FormGroups = new SelectList(formGroups, "FormGroupId", "Title", "3");
}
public int FormTypeId;
public string Title;
public SelectList FormGroups;
public int SelectedFormGroup;
}
和繼承人的看法:
@for (int i = 0; i < Model.FormTypeFormGroupViewModels.Count; i++)
{
<tr>
<td>
@Model.FormTypeFormGroupViewModels[i].Title
</td>
<td>
@Html.DropDownListFor(model => Model.FormTypeFormGroupViewModels[i].SelectedFormGroup, Model.FormTypeFormGroupViewModels[i].FormGroups)
</td>
</tr>
}
終於控制器是:
[HttpPost]
[UnitOfWork]
public String Associations(FormGroupsAssociationViewModel model)
{
String s = string.Empty;
foreach (var formTypeFormGroupViewModel in model.FormTypeFormGroupViewModels)
{
s = s + formTypeFormGroupViewModel.SelectedFormGroup.ToString();
}
return s;
}
我有問題是SelectedFormGroup將返回0,而不是實際的了selectedValue。如果有人有任何想法,他們將不勝感激。
乾杯
