How can I access html elements in MVC

Question

Hello Below is an example that was done through Asp.net code-behind. Does anyone know how we can accomplish the same task using MVC controller? Here is the link in case you are interested: https://www.mikesdotnetting.com/article/101/persisting-the-position-of-jquery-draggables-in-asp-net public partial class PersistDraggable : Page { protected void Page_Load( object sender EventArgs e) { Coordinates coords = new Coordinates(); DataTable dt = coords.GetSavedCoords(1); foreach (DataRow row in dt.Rows) { HtmlControl ctl = (HtmlControl) this .FindControl(row[ element ].ToString()); if (ctl != null ) { ctl.Style.Add( left  row[ xPos ].ToString() + px ); ctl.Style.Add( top  row[ yPos ].ToString() + px ); } } } } Thank you for reading this post.

Harish thank you for the advice but that wasn't my goal. If you read the link I provided in my original post I am trying to do the same thing the Author of the tutorial by retrieving the coordinates of a persistent panel from the database which is below: foreach (DataRow row in dt.Rows) { HtmlControl ctl = (HtmlControl) this .FindControl(row[ element ].ToString()); if (ctl != null ) { ctl.Style.Add( left  row[ xPos ].ToString() + px ); ctl.Style.Add( top  row[ yPos ].ToString() + px ); } } The problem is that the code above was written for web form and I don't know how to convert it so that it would work in Mvc controller action. Hope that explains it.

In asp.net (MVC) code is devided into 3 different parts i.e. model views and controller. here forget about model. we will focus on view and controller. your query is how to catch data comming from view in controller action methods. If I catch you correctly then pls go through below code 1. view page code (Login) @using (Html.BeginForm(Login Welcome FormMethod.Post)) { @Html.Label(Username) @Html.TextBox(txtUserName) : user @Html.Label(Password) @Html.TextBox(txtPassword) : pass } 2.Controller class Login action method code (WelcomeController) public ActionResult Login() { return View(); } [HttpPost] public ActionResult Login() { string userName = Request.Form[txtUserName]; string password = Request.Form[txtPassword]; } OR you can also try for below. [HttpPost] public ActionResult Login(FormCollection collection) { string userName = collection[txtUserName]; string password = collection[txtPassword]; } Please Note this: this code is only for understanding purpose. It might be have error. hope you understood.
