I really feel like this should be easy but I’m thinking it may have changed with .Net 6. I can pass values to my controller with the input “name=’name’” but for some reason I cannot get any values from my model into my controller. I am trying to POST my row values to the controller. I am using an enumerable. I’m not sure if I should be using a or not. Another thing is how should I be populating my table row from a loop of the model. I thought using @Html. Was for older .net and tag helpers are the new way but I couldn’t get any to work populating my rows.

<form method="post">
        <div id="tblPullParts" >
       
            <table >
           
                <thead>
                    <tr>
                        <th></th>
                        <th >Order #</th>
                        <th >Item</th>
                        <th >Description</th>
                        <th >Quantity</th>
                    </tr>
                </thead>
                <tbody>
                    @foreach (var p in Model)
                    {
                        <tr>
                            <td><input type="radio" id="radio" name="radio"
                                value="@Html.DisplayFor(item => p.PartID)" /></td>
@*<td><input asp-for="Selected" type="radio" value="Selected" /></td>*@
                            <th scope="row">@Html.DisplayFor(item => p.PartID)</th>
                            <td>@Html.DisplayFor(item => p.Name)</td>
                            <td>@Html.DisplayFor(item => p.ItemLocation)</td>
                            <td>@Html.DisplayFor(item => p.PartGroup)</td>
                            <td>@Html.DisplayFor(item => p.Description)</td>
                            <td>
                                <input type="text" asp-for="@p.Name" id="txtNameN" />
                            </td>
                        </tr>
                    }
                    
                </tbody>

            </table>

            <input type="text" id="txtName" name="txtName" value="" />

        <div >
            <button type="submit" >Start Pick</button>

        </div>
     </form>

[HttpPost]
        public async Task<IActionResult> Index( PartVM model, string radio, string txtName)
        {
            
            if (model?.PartID != 0)
            {
                return View("UpdatePickQuantity", model);
            }

            if (!String.IsNullOrWhiteSpace(txtName))
            {

            }

            //Request.QueryString["radio"];
            var lstParts = await _ordersService.GetAllParts();

            return View(lstParts);
        }

CodePudding user response：

@Html.DisplayFor() can only display the value of model, If you want to submit the value, You need to use <input>,Here is a simple demo, I add hidden input in your form to submit the value:

@model List<PartVM>
@{
    int i = 0;
}

    <form method="post">
        <div id="tblPullParts" >
       
            <table >
           
                <thead>
                    <tr>
                        <th></th>

                        <th >Item</th>
                        <th >Description</th>
                        <th >Quantity</th>
