Hi,

I have a label used in my view page as below

@Html.Label("label1")

I want to change the text of a label from the controller's action method. It shoud be something like the below code which we can set in the asp.net webform

//from the code behind function

label1.Text="new text";

Can some one please check and help me to resolve the issue?

Accepted answer

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult UpdateLabelText(string selectedValue)
    {
   
        string updatedText = "Updated text based on " + selectedValue;
        return Content(updatedText);
    }
}

@{
    ViewBag.Title = "Dynamic Label Text Example";
}

Dynamic Label Text Example

@Html.DropDownList("dropdown", new SelectList(new[] { "Option 1", "Option 2", "Option 3" }))

Thanks for your reply, the method which you suggest will work in ach page load, but in my case the action method with get involked each time when I am changing the selection in the dropdown. At the same time I want to show the updated text in the label also.

If you are using asp.net mvc

public ActionResult YourAction()
{
    ViewBag.LabelText = "new text"; // Set the new text
    return View();
}

Your view

@Html.Label("label1", ViewBag.LabelText)
