Question

I have a dropdown list that is populated on a content page like this

<%: Html.DropDownListFor(x => x.SelectedName, Model.NameList)  %>
<input name="btnGo" type="submit" value="GO"  />

When the user selects the name and click the GO button, I have an HTTP Action that gives me the name

[HttpPost]
public ActionResult SelectName(string SelectedName)
{
...
}

Now I want to take that name and set a lable on the master with the SelectedName
in MVC2 how is this accomplished?

Remember, this is not Web Forms. 🙂

In other words, you can’t do this in the Controller action:

someLabel.Text = "foo"

Your best bet would be to put the text you want in the ViewData:

[HttpPost]
public ActionResult SelectName(string SelectedName)
{
   ...
   ViewData["SelectedText"] = "some text";
   return View();
}

And then set the Label to that in your Master View:

<span><%: ViewData["SelectedText"] %></span>
