Answer 1

You can add the result to ViewData. For example:

if (SaveToDbOK)
{
    ViewData["Success"] = "Data was saved successfully.";
   // Do other things or return view
}

In your view you can place anywhere:

MVC2:

<% if (ViewData["Success"] != null) { %>
    <div id="successMessage">
        <%: ViewData["Success"] %>
    </div>
<% } %>

MVC3:

@if (ViewData["Success"] != null) {
    <div id="successMessage">
        @ViewData["Success"]
    </div>
@}

I used this approach in my last project in order to make the information returned from the server unobtrusive. Checking whether ViewData["Success"] or ViewData["Failure"] are done in the Master page, the divs are formatted using CSS, jQuery code was used to hide the notifications after 5 seconds.

Answer 2

public ActionResult UploadPropertyImage()
{
    // Business logic....
    return Content("<script language='javascript' type='text/javascript'>alert('Save Successfully');</script>");
}
