Pass table Object from view to controller using asp.net mvc - asp.net-mvc

Question

I am new to ASP.net MVC still in learning stage :) Thank you Advance
I have created the View Model to populate the table data based on the PName which I have selected.
Ex: for 1 project we have 10 related Items in , i am displaying all the rows on the screen, and making some updates to those rows to save it back to Database.
I am able to get the data but when I am trying to send the table object to controller to save, it always giving me null
Here is my ViewModel
namespace Application.ViewModel.Projects
{
public class PUpdates
{
public List<FItems> items{ get; set; }
}
}
CSHTML code
#using (Html.BeginForm("PFItems", "Projects", FormMethod.Post))
{
<table id="test">
<tr id="testtr">
<th id="testth"></th>
<th id="testth"></th>
</tr>
#foreach (var item in Model.FItems)
{
<tr id="testtr">
<td id="testtd">
#Html.Label(item.Ftype)
</td>
<td id="testtd">
#Html.TextBox("test", item.AC)
</td>
</tr>
}
<tr> <td><input type="submit" value="Submit" /></td></tr>
</table>
}
Controller Code
[HttpPost]
public PartialViewResult PFItems(PFUviewmodel)
{
return PartialView(viewmodel);
}
I am not able to get my table Object to make the update

Welcome to Stack overflow :)
For model binding to work you need to give you fields an index in the name property. Have a look at this question where I answered a very similar question and explained it.
In your case you need to do something like the following:
#model Application.ViewModel.Projects.ProjectfinanceUpdate
#using (Html.BeginForm("PartialprojectFinanceItem", "Projects", FormMethod.Post))
{
<table id="test">
<tr id="testtr">
<th id="testth">Financial Type</th>
<th id="testth">Actual Cost</th>
</tr>
#var i =0;
#foreach (var item in Model.tblFinanceItems)
{
<tr id="testtr">
<td id="testtd">
#Html.Label(item.FinancialType)
</td>
<td id="testtd">
<input name="ProjectfinanceUpdate.tblFinanceItems[#i].ActualCost" value="#item.ActualCost"/>
</td>
</tr>
#i++;
}
<tr> <td><input type="submit" value="Submit" /></td></tr>
</table>
}
The important part is that model binding works off of the name property, and because it's a list, it needs to have an index property.
Hope that helps.
