ComboBox and EmptyMessage

[Michael]

I'm using a radcombobox to populate items  from a database on demand.  All works well except for when EmptyMessage is set

The Problem:

    On the first attempt to drop the box down, it displays no matches and nothing comes up in the list.  The second dropdown attempt everything works perfectly.  Happens only when the EmptyMessage property is set.  I'm stumped.

----
Here is what my code looks like:

.aspx and javascript

<telerik:RadComboBox ID="cboCities" runat="server" AutoPostBack="True" EnableLoadOnDemand="True"
                                                            EnableVirtualScrolling="True" Height="200px" MarkFirstMatch="True"
                                                            OnClientItemsRequesting="OnClientItemsRequesting"
                                                            OnItemsRequested="cboCities_ItemsRequested" Filter="None" ShowMoreResultsBox="True"
                                                            Width="240px" Font-Size="X-Small" AllowCustomText="True"
                                                            EmptyMessage="Type a city name" Skin="Black">
                                                            <CollapseAnimation Duration="200" Type="OutQuint" />
                                                        </telerik:RadComboBox>

function OnClientItemsRequesting(sender,e)
{
    if(sender.get_appendItems())
        e.get_context().CustomText="";
    else
        e.get_context().CustomText=sender.get_text();
}

Finally the codebehind:

Protected Sub cboCities_ItemsRequested(ByVal sender As Object, ByVal e As RadComboBoxItemsRequestedEventArgs)

        Dim sql As String = "Select cityCode,cityName,State,Lat,Long from s_CityMaster WHERE Cityname LIKE '%" + e.Context("CustomText").ToString() + "%' ORDER BY CityName"

        Dim adapter As New SqlDataAdapter(sql, ConfigurationManager.AppSettings("BioDiasporaCS"))
        Dim data As New DataTable()
        adapter.Fill(data)

        Try

            Dim itemsPerRequest As Integer = 10
            Dim itemOffset As Integer = e.NumberOfItems
            Dim endOffset As Integer = itemOffset + itemsPerRequest
            If endOffset > data.Rows.Count Then
                endOffset = data.Rows.Count
            End If

            If endOffset = data.Rows.Count Then
                e.EndOfItems = True
            End If
            Dim i As Integer = itemOffset
            While i < endOffset
                cboCities.Items.Add(New RadComboBoxItem(data.Rows(i)("cityName").ToString(), data.Rows(i)("cityName").ToString()))
                i = i + 1
            End While

            If data.Rows.Count > 0 Then
                e.Message = [String].Format("Items <b>1</b>-<b>{0}</b> out of <b>{1}</b>", endOffset.ToString(), data.Rows.Count.ToString())
            Else
                e.Message = "No matches"
            End If
        Catch
            e.Message = "No matches"
        End Try
    End Sub

Can anyone help me with what I'm doing wrong? Thanks in advance.
