I have searched the forums and seen where other people's issues have been resolved... however, mine is still not working. What am I doing wrong? I have tried toggling delay on/off, triggeraction on/off, minchars set/not set, querymode local/remote... no matter what combination of options I try, the typeahead feature is not ever working... the combobox just shows the top of the list and that's it. I am auto loading my store directly from the model... thoughts?

Html.X().ComboBox()
            .ID("cboBIAAppSelection")
            .Width(400)
            .MarginSpec("0 0 0 5")
            .TypeAhead(true)
            .TypeAheadDelay(500)
            .QueryMode(DataLoadMode.Local)
            .TriggerAction(TriggerAction.All)
            .MinChars(0)
            .SelectOnFocus(true)
            .EmptyText("")
            .Editable(false)
            .ListConfig(new BoundList { Cls = "biaDropdown" })
            .FieldLabel("Select BIA App")
            .LabelCls("biaFormLabel")
            .DisplayField("PortalAppName")
            .ValueField("PortalAppID")
            .Store(
                Html.X().Store()
                .DataSource(Model.BIA_Apps.OrderBy(o => o.PortalAppName))
                .AutoLoad(true)
                .Model(Html.X().Model()
                    .Fields(
                        new ModelField("PortalAppID", ModelFieldType.String),
                        new ModelField("PortalAppName", ModelFieldType.String)
                    )
                )
            )
