[Solved] Combo box bug(?) when using filtering and one of the display text is empty

[Sang]

Combo box errors out (i.e. Firebug shows error message: g.toLowerCase is not a function) when one of the display text is an empty text and if you chose .Filterable

To replicate, use the example below and try to type any text in the box - like e - and the combo box will not select the second item, but the browser status will show that it has an error.

I would like to see filtering work despite of having one of the "Text" being empty.  Temporary workaround I am using is to populate the empty text value with some dummy text, so the combo box does not error out.

I am using version: 2011.1.315

Controller

public ActionResult Test()
{
   var list = new List<SelectListItem>
    {
        new SelectListItem
            {
                Selected = true,
                Value = "v1",
                Text = ""
            },
            new SelectListItem
            {
                Selected = false,
                Value = "v2",
                Text = "Second Choice"
            }
    };
   var sel = new SelectList(list, "Value", "Text");
    return View(sel);
}

View

@model SelectList
@(Html.Telerik().ComboBox()
            .Name("ComboBox")
            .SelectedIndex(0)
            .BindTo(Model)
            .Filterable(filtering  => filtering.FilterMode(AutoCompleteFilterMode.Contains))
)

Hello Sang,

 
Thank you for drawing our attention to this issue.

The problem will be addressed with the next official release of Telerik extensions for ASP.NET MVC. The fix also will be available in the next internal build.

I have updated your Telerik points.
