[Solved] DropDownList Item Value Not Returning

[Brian Lehmann]

I'm having a problem retrieving the value of a DropDowList item. I'm subscribing to the onChange event of the control and in that event I'm doing a simple test to retrieve the value, however each time I get back the text.

My DropDowList is defined as follows:

<%
                        List<ListItem> list_items = new List<ListItem>
                                                        {
                                                            new ListItem {Text = "List", Value = "1"},
                                                            new ListItem {Text = "Map", Value = "2"},
                                                            new ListItem {Text = "Chart", Value = "3"}
                                                        };
                        Html.Telerik().DropDownList()
                            .Name("DropdownBox")
                            .BindTo(new SelectList(list_items))
                            .SelectedIndex(0)
                            .ClientEvents(events => events.OnChange("listChange"))
                            .Render();
                    %>

And my event handler has code that looks like this:

var combobox = $(this).data('tDropDownList');
console.log(combobox.text());
console.log(combobox.value());

When I check the console in Firebug, both lines display the Text value that was selected with the value nowhere to be found.

Is there something I'm missing here? I'm on version 2011.1.414. . .

Thanks in advance for the help!

Another quick update - it seems I have to use the Text value to change to change the value as well.

For instance, this has no effect:

var combobox = $('#DropDownList').data('tDropDownList');
combobox.value('1');

But this works:

var combobox = $('#DropDownList').data('tDropDownList');
combobox.value('Chart');

Hello Brian Lehmann,

 
When creating SelectList from custom object, you will need to define dataTextField and dataValueField.
Check this article for more information.
Also you can check this online demo, which shows how to use it.

All the best,
