Hi, I'm using RadComboBox ("RadControls for ASPNET AJAX Q1 2008") with load on demand.  I seem to have it half-working.  It will successfully display "1-10 of 8836", and when I type in the first few letters of any of the first ten items in the list it will successfully highlight that item which matches.  The problem is that when I type in letters which should match items which are not in the first ten it will not find it; it will say "Loading..." for a few seconds but then "Loading..." will disappear and no items will be selected even though I have confirmed that what I'm searching for should be in the list based on what I'm seeing in the database.

My code is below, most of which I copied from your website:
http://www.telerik.com/DEMOS/ASPNET/Prometheus/ComboBox/Examples/PopulatingWithData/AutoCompleteSql/DefaultVB.aspx

<asp:GridView Width=100% ID="gvLines" runat=server AutoGenerateColumns=false>
<HeaderStyle CssClass=dgheader/>
<RowStyle CssClass=dgrows />
<Alternatingrowstyle CssClass=dgalternating />
<Columns>
<asp:TemplateField HeaderText="Customer">
<ItemTemplate>
    <telerik:RadComboBox
        ID="RadComboBox1" runat="server" Width="250px" Height="200px"
                AllowCustomText="True" ShowToggleImage="True" ShowMoreResultsBox="true"
                    EnableLoadOnDemand="True" MarkFirstMatch="True" OnItemsRequested="RadComboBox1_ItemsRequested" EnableVirtualScrolling="true">
    </telerik:RadComboBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

-------------------------------------

Protected Sub RadComboBox1_ItemsRequested(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs)

Dim sql As String = "SELECT CUSTOMER = RTRIM(CUST_NO) + ' - ' + CUST_NAME from DATA_POOL.DBO.Customer (NOLOCK) "

Dim adapter As New SqlDataAdapter(sql, conn)
Dim data As New DataTable()
adapter.Fill(data)

Dim rcb As RadComboBox = CType(o, RadComboBox)

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
        rcb.Items.Add(New RadComboBoxItem(data.Rows(i)("CUSTOMER").ToString(), data.Rows(i)("CUSTOMER").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

Is there something wrong with my method of initiating a server side radAlert?
Each time i press button1, the memory for iexplore.exe jumps up a few K, and every time thereafter. So it only takes a dozen or so clicks to go from 30K->70K. If I replace the RadAlert with a normal javascript alert in the code there is no problem.
