Necessary input in Html.TextBoxFor

Question

Necessary input in Html.TextBoxFor

Is there a way to format the value of a TextBox using the following structure:

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

Initially, this format works as intended. However, when a default value is set for the TextBox:

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

An issue arises where an empty value is accepted despite the generation of the following Html code:

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

What could be causing this problem?
Are there any solutions to address this issue?

For some reason, I discovered that deleting the space between = and @ fixes the issue.

<td>@Html.TextBoxFor(m =>(m.Code), new { @Value <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="764b363b1912131a5835191213">[email protected]</a>, @required  = "required"})</td>

Strange but true!

Include the following code snippet to validate the code property:

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

To define the code property, use the following code:

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

To set the value in the code Textbox from the controller:

Model.Code="fffff";

In the view, use the following code:

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

Don't forget to include the validation JavaScript files:

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

Give it a try and see how it works!

Avoid using parentheses

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

By assigning the value to 'code' on the controller side, it will automatically populate the text box.
