Question

my application is asp.net I am passing a variable from the controller to a view using:

 public ActionResult Create(long? learnerID)
    {
        learnerID = 211;
        ViewBag.learnerID = learnerID.Value;
        return View();
    }

In the view:

 <input type="text" value="<%=  ViewBag.learnerID %>" id="Learner_ID" name="Learner_ID" />

The value 211 shows in form and I can save it, however if I change the input type to hidden or use style=”display:none” I get the following error:

The call is ambiguous between the following methods or properties: 'System.IO.TextWriter.Write(string, params object[])' and 'System.IO.TextWriter.Write(char[])'

Would appreciate your suggestions. Thanks in advance.

Answer 1

Try adding a call to ToString()

<input type="text" value="<%=  ViewBag.learnerID.ToString() %>" id="Learner_ID" name="Learner_ID" />
