Required value in Html.TextBoxFor

Question

I need to put the value of a TextBox required like this :

<td>@Html.TextBoxFor(m =>(m.Code), new { @required  = "required"})</td>

It works. But if i set a default value to the TextBox

<td>@Html.TextBoxFor(m =>(m.Code), new { @Value = @Model.Code, @required  = "required"})</td>

An empty value becomes accepted despite the generation of this Html code

<td><input id="Code" name="Code" required="required" type="text" value="fff       "></td>

1. What is the source of this problem?
2. How can i fix it?

Solution 1

I don't know why but when i delete the space between = and @

<td>@Html.TextBoxFor(m =>(m.Code), new { @Value [email protected], @required  = "required"})</td>

it works

Solution 2

Use

@Html.ValidationMessageFor(m => m.Code)

for validating the code property.and code Property should be define like this-

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

and for setting the value in code Textbox.You can set it in controller like this.

Model.Code="fffff";

and on the view use like this-

<td>@Html.TextBoxFor(m =>(m.Code), new { @Value = @Model.Code)</td>
 @Html.ValidationMessageFor(m => m.Code)

and yes dont forgot to include the validation Js i.e

 <script src="/Scripts/jquery.validate.unobtrusive.js"></script>
    <script src="/Scripts/jquery.validate.unobtrusive.min.js"></script>

Try it:-

Solution 3

you don't need the parens

@Html.TextBoxFor(m => m.Code, new { @class = "txtCode" })

if you set code on the controller side the value will be put in the text box

Yes your validation should be in your models like in this post. It will become a mess if you do it on the view, especially when you want to do custom error messages.

How to do this dynamically rather than on submit?
