Most of the Tutorials, Questions I found online where about when the Model has one List of Items. But In my Case I have a List of Items which further have a List of Items.
I have a ViewModel with List of ItemA
, and ItemA
has a list of ItemsB
public class ViewModel
{
List<ItemA> Items { get; set; }
public ViewModel()
{
Items = new List<ItemA>();
}
}
public class ItemA
{
public int ItemAId { get; set; }
public List<ItemB> ItemBList { get; set; }
public ItemA()
{
ItemBList = new List<ItemB>();
}
}
public class ItemB
{
public int ItemBId { get; set; }
// Need to input this string for each Item in List<ItemA>
public string NewInput
}
My View:
@Html.BeginForm(){
@foreach (var itemA in Model.Items)
{
<p>@itemA.ItemAId</p>
for (int i = 0; i < itemA.ItemBList.Count; i++)
{
@Html.HiddenFor(m => itemA.ItemBList[i].ItemBId )
@Html.TextBoxFor(m => itemA.ItemBList[i].NewInput)
}
<button type="submit">Submit</button>
}
}
My Controller:
public ActionResult SaveInfo(ViewModel model){
// Update
}
My Question is how do I write a Form for this Case so it binds back to ViewModel in Controller?
