The load on demand for the combobox is not working once I move the page to the shared host. It works fine while testing it in Visual Studio.
Up on the shared host, when I click on the combobox, it drops down showing the items in the box. But, as soon as I type a single letter, the "Loading..." message appears and it just sits there. Even if I type the first letter of the first item in the box, it will show the loading message and then do nothing.

I tried both loading from server side, and also by setting the EnableAutomaticLoadOnDemand="true". The latter doesn't even load the list.

This will at least display the list:

<telerik:RadComboBox ID="CustomerSearch" runat="server" Width="180" Height="160"

MarkFirstMatch="true" AllowCustomText="true" CssClass="CustomerSearch"

EnableLoadOnDemand="true" EnableVirtualScrolling="true" OnItemsRequested="CustomerSearch_ItemsRequested"

OnClientSelectedIndexChanged="searchnav" EmptyMessage="Select a customer" DataSourceID="dsCustomer" DataTextField="CustomerName"

DataValueField="NavPath" BackColor="White" Skin="Forest" />

<asp:SqlDataSource ID="dsCustomer" runat="server"

SelectCommand="CustomerSearchName" SelectCommandType="StoredProcedure">

</asp:SqlDataSource>

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script type="text/javascript">

function searchnav(sender, args) {

var iframe = document.getElementById('ctl00_iMainPages');

iframe.src = sender.get_value();

}

</script>

</telerik:RadScriptBlock>

This is the code-behind:

Protected Sub CustomerSearch_ItemsRequested(sender As Object, e As RadComboBoxItemsRequestedEventArgs)

Dim dal As New Customer

Dim data As DataTable = dal.CustomerSearchName(Session("StoreID"), e.Text).Tables(0)

Dim itemOffset As Integer = e.NumberOfItems

Dim endOffset As Integer = Math.Min(itemOffset + 10, data.Rows.Count)

e.EndOfItems = endOffset = data.Rows.Count

For i As Integer = itemOffset To endOffset - 1

CustomerSearch.Items.Add(New RadComboBoxItem(data.Rows(i)("CustomerName").ToString(), data.Rows(i)("NavPath").ToString()))

Next

e.Message = GetStatusMessage(endOffset, data.Rows.Count)

End Sub

Private Shared Function GetStatusMessage(ByVal offset As Integer, ByVal total As Integer) As String

If total <= 0 Then

Return "No matches"

End If

Return [String].Format("Items <b>1</b>-<b>{0}</b> out of <b>{1}</b>", offset, total)

End Function
