How does the listbox helper in asp.net mvc work?


Asked by Myra Dalton on Dec 07, 2021 ASP.NET



The ListBox HTML helper renders the HTML <select> element with the multiple attribute, which allows the users to make multiple selections. Navigate to the Test link, then select the Multi Select Country link. The rendered UI allows you to select multiple countries. In the image below, Canada and China are selected.
Subsequently,
The benefit of using ListBoxFor is, all the options visually appear and a user has the option to select one option as well as more than one options. Here, in this tutorial, I will explain, how to create ListBox in ASP.NET MVC using List Items and then post selected items to controllers.
And, Just to recap, an MVC Html.DropDownList helper is rendered to the browser as an HTML <select> element. They are mainly employed to provide the user with a means to select one of a number of options.
Also Know,
Html helpers are always starting with @HTML and It is an object of Html helper class.@ symbol is used to access the server-side code. The extension method of the Html helper class has several overloaded methods. we can use it as per our requirement. Html is a property of type HtmlHelper included in base class of razor view WebViewPage.
Moreover,
In order to create a checkbox list in ASP.NET MVC Application, we are provided with the CheckBox HTML Helper method. The HtmlHelper class provides two extension methods to generate a <input type=”checkbox”> element in an ASP.NET MVC view.
