The value for OData $orderby cannot be empty

[Richard]

Trying to use an ODataDataSource with a RadSearchBox.  When I try to use it, I get the following error:

The query specified in the URI is not valid. The value for OData query '$orderby' cannot be empty.

Is there a way to set an orderby that I can pass?  I don't see an option (or maybe I'm going nuts - could be) and it appears as though the ODataDataSource is just passing a blank $orderby= in the query string. 

Thanks,

Richard

Hello,

The provided information is not enough th troubleshoot the issue. Our online demos demonstrate a working scenario with the SearchBox bound to an ODataDataSource:
http://demos.telerik.com/aspnet-ajax/searchbox/examples/populatingwithdata/defaultcs.aspx

I've also tested the following markup which is working on my end:

<telerik:RadODataDataSource runat="server" ID="DataSource1">
    <Transport>
        <Read Url="http://demos.kendoui.com/service/Northwind.svc/"></Read>
    </Transport>
    <Schema>
        <telerik:DataModel ModelID="Product" Set="Products">
            <telerik:DataModelField FieldName="ProductID" />
            <telerik:DataModelField FieldName="ProductName" />
        </telerik:DataModel>
    </Schema>
</telerik:RadODataDataSource>
<telerik:RadSearchBox RenderMode="Lightweight" runat="server" ID="RadSearchBox1"
    ODataDataSourceID="DataSource1"
    DataModelID="Product"
    DataKeyNames="ProductID, ProductName"
    DataValueField="ProductID"
    DataTextField="ProductName">
    <DropDownSettings Height="400" Width="300" />
</telerik:RadSearchBox>
