Question

I am developing an application where I need to pass the value of username from a controller to a view.
i tried ViewData as given in http://msdn.microsoft.com/en-us/library/system.web.mvc.viewdatadictionary.aspx

My code in controller is

public ActionResult Index(string UserName, string Password)
{
        ViewData["UserName"] = UserName;
        return View();
}

where username and password are obtained from another form.

And the code in the view is

@{
    ViewBag.Title = "Index";  
}
<h2>Index</h2>
<%= ViewData["UserName"] %>

But when I run this code, the display shows <%= ViewData[“UserName”] %> instead of the actual username say, for example “XYZ”.

How should I display the actual UserName?

Thank you very much in advance for your help.

You’re using razor syntax here but you’re trying to mix it with older asp.net syntax, use

@ViewData["UserName"] 

instead

Also, normally you wouldn’t use the view bag to pass data to the view. Standard practice is to create a model (a standard class) with all of the bits of data your View (page) wants then pass that model to the view from your controller (return View(myModel);)

To do this you also need to declare the type of model you’re using in your view

@model Full.Namespace.To.Your.MyModel
