Hi,

I am trying to get the value of ViewData on view when DropDownListFor selection is changed.

Scenario:
I have created a view with a dropdown, and a label.

HTML

<div class="FQA">Quote:</div> <div>
            <%:Html.DropDownListFor(x=>x.Person.Days, new SelectList(Model.Person.Days), new {onChange = "this.form.action='Home/SelectedIndexChanged';this.form.submit();" } )%>
        </div>
<%:ViewData["ddlVal"].ToString() %>

Action

C#

public ActionResult SelectedIndexChanged() {
            ViewData["ddlVal"] = "Changed";
            }

Now i want to update the label with drop down selected item data when drop down selection is changed.

you can simply add a line in your code...

Quote:
public ActionResult SelectedIndexChanged() {
ViewData["ddlVal"] = "Changed";
}

add this :

C#

public ActionResult SelectedIndexChanged() {
            ViewData["ddlVal"] = "Changed";
            return View(YourViewName);
            }

This might work. Let me know if any issues...
