Question

Im sitting here scratching my head with a validation problem in ASP MVC3.

Somehow I’m able to validate the field Quantity, but the field OrderNumber does not validate. I can leave it empty and it still accepts it. I’ve tried to add other restrictions to it as well (such as max and min length) but same result – it accepts anything.

I also try changing ‘TextBoxFor’ to ‘EditorFor’ – but it’s the same result.

Quantity on the other hand works as I want it. It requires you to enter an integer and it cannot be blank.

Hopefully some of you will be able to see what I’m doing wrong here 🙂

Here is my model:

public class Order
{
    [Required(ErrorMessage="Insert Ordernumber (6-digits)")]
    public string OrderNumber { get; set; }

    [Required]
    public string Partnumber { get; set; }

    [Required]
    public long Quantity { get; set; }

    public Order()
    {
    }
}

And here is my view :

model POWeb.Models.AddModel

@using (Html.BeginForm(“Add”, “Home”, FormMethod.Post))
{

//Create table
<table>
    <tr>
        <td>Select Partnumber to produce</td>
        <td>@Html.DropDownListFor(model => model.SelectedPartNumber, Model.PartNumbers)</td>
    </tr>

    <tr>
        <td>Enter PO number</td>
        <td>@Html.TextBoxFor(model => model.OrderNumber)@Html.ValidationMessageFor(model => model.OrderNumber)</td>
    </tr>

    <tr>
        <td>Quantity</td>
        <td>@Html.TextBoxFor(model => model.Quantity)@Html.ValidationMessageFor(model => model.Quantity)</td>
    </tr>

    <tr>
        <td colspan="2">
            <button type="submit" name="SubmitButton">Add</button>
        </td>
    </tr>

</table>

}

You have the view of type POWeb.Models.AddModel, but you try to validate Order type. I’m pretty sure validation attributes on those types are not the same, so you get problems
