Creating Hidden Field in ASP.NET MVC

Creating Hidden Field in ASP.NET MVC

Hidden fields are used to store data on a web page without displaying it to the user. In ASP.NET MVC, you can create hidden fields using HTML helpers or by manually rendering the HTML markup. Here's how you can create a hidden field in ASP.NET MVC:

1. Using HTML Helper:

You can use the HiddenFor method provided by the Html class to create a hidden field for a model property.

csharp
@model YourModel

@using (Html.BeginForm("Action", "Controller", FormMethod.Post))
{
    @Html.HiddenFor(model => model.HiddenProperty)
    <input type="submit" value="Submit" />
}

Explanation:

• The @model directive at the beginning specifies the model type that the view expects.
• The @using statement is used to import the necessary namespaces.
• Html.BeginForm creates an HTML form that will submit to the specified action and controller.
• Html.HiddenFor generates a hidden field for the HiddenProperty of the model.

2. Manually Rendering the Hidden Field:

Alternatively, you can manually render the hidden field using the Html.Hidden method.

csharp
@using (Html.BeginForm("Action", "Controller", FormMethod.Post))
{
    @Html.Hidden("HiddenProperty", Model.HiddenProperty)
    <input type="submit" value="Submit" />
}

Explanation:

• The Html.Hidden method generates a hidden field with the specified name and value.
• The first parameter "HiddenProperty" is the name of the hidden field.
• The second parameter Model.HiddenProperty is the value to be stored in the hidden field.

Summary: In ASP.NET MVC, you can create hidden fields using HTML helpers like HiddenFor or manually render them using Html.Hidden. Hidden fields are useful when you need to store data on the page without displaying it to the user.
