Question

I am passing a list from my controller to my view, and then inside a form I loop through each list item and display a table with some textboxes that need to be filled in for each item.

What I then want to do is submit the data back to my controller, look through it to grab the results of what was entered, and save to database.

How do I do this?? I have put my code below

CONTROLLER

public ActionResult GetListOfDogs()
{
var list = db.dogs;  //gets multiple dogs 
return View(dogs);

///Dog object looks like this
///int Id 
///string DogName 
///string RegNumber 
///string Breed 
}

[HttpPost]
public ActionResult SaveDogInfo(string[] RegNumber, string[] Breed)
{

}

VIEW

GetListOfDogs.cshtml

@model Dog

@using(Html.BeginForm("SaveDogInfo", "Dog", FormMethod.Post))
{
<table>
    <tr>
        <th>Name</th>
        <th>Reg Number</th>
        <th>Breed</th>
    </tr>
    @foreach (var item in Model)
    {
        <tr>
            <td>@item.DogName</td>
            <td>@Html.TextBox("RegNum", null, new{id = "dId_=" + @item.Id})</td>
            <td>@Html.TextBox("Breed", null, new{id = "breed_=" + @item.Id})</td>
        </tr>
    }
</table>
<input type="Submit" value="Save" />

}

Inside my ‘SaveDogInfo’ action, I can view the results for RegNumber and Breed, but there is no id coming back with them, so I have no way of matching the result with the actual DogId it belongs to..

Can anyone help or am I just totally missing the point???

Cheers

Your model of your view should be something enumerable, no ?

@model IList<Dog>

then use a for loop, and add an hidden field for Id. !

@for (var i = 0; i < Model.Count(); i++) 
    {
        <tr>
            <td>@Html.DisplayFor(m => Model[i].Name</td>
            <td>@Html.TextBoxFor(m => Model[i].RegNumber)</td>
            <td>
                @Html.TextBoxFor(m => Model[i].Breed)
                @Html.HiddenFor(m => Model[i].Id)
           </td>
        </tr>
    }

then your post action should become

[HttpPost]
public ActionResult SaveDogInfo(IEnumerable<Dog> dogs)
{

}
