I have a Combobox and grid in a widget.  The grid needs to be filtered as the selection in the combobox changes.  Currently when the selection changes, the grid reloads, but always displays the same data.  Any ideas how to fix this?  Or even debug it?

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>
 
<telerik:RadScriptManager runat="server" ID="RadScriptManager1" />
<telerik:RadFormDecorator ID="QsfFromDecorator" runat="server" DecoratedControls="All" EnableRoundedCorners="false" />
 
<label for="NamesDDL">Select plant name to view its reports:</label>
<div style="margin-top: 15px;">
    <telerik:RadComboBox ID="NamesDDL" runat="server" AutoPostBack="True" DataSourceID="dllDataSource"
        DataTextField="PlantNameAndID" DataValueField="PlantID" Width="250px" Height="150px"
        AppendDataBoundItems="true" >
        <Items>
            <telerik:RadComboBoxItem Text="All" Value="0" Selected="true"></telerik:RadComboBoxItem>
        </Items>
    </telerik:RadComboBox>
</div>
 
<div style="margin: 15px 0 20px;">
    <telerik:RadGrid ID="OrdersGrid" AllowPaging="true" DataSourceID="gridSource" runat="server"
        GridLines="None" AllowSorting="true" HeaderStyle-ForeColor="Black" HeaderStyle-HorizontalAlign="Center">
    </telerik:RadGrid>
</div>
 
<asp:SqlDataSource ID="dllDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:Dev-TestOilConnectionString %>"
    SelectCommand="select customer.plant.PlantID, customer.plant.PlantNo, customer.plant.PlantName, customer.plant.PlantID, cast(customer.plant.PlantID as varchar) + ' - ' + customer.plant.PlantName as PlantNameAndID from customer.plant where plant.CustID = 10 order by plant.PlantNo"></asp:SqlDataSource>
 
<asp:SqlDataSource ID="gridSource" runat="server" ConnectionString="<%$ ConnectionStrings:Dev-TestOilConnectionString %>"
    SelectCommand="select LabID, SampleDate, MachCond, LubCond, CustReview, CustReviewDte, machine.PlantID from customer.plant inner join customer.machine on machine.PlantID = plant.PlantID inner join sample.sample on sample.PointID = machine.PointID where ((machine.PlantID = @PlantID and @PlantID <> 0) or (machine.PlantID = machine.PlantID and @PlantID = 0)) and plant.custid = 10">
    <SelectParameters>
        <asp:ControlParameter Name="PlantID" PropertyName="SelectedValue" ControlID="NamesDDL"></asp:ControlParameter>
    </SelectParameters>
</asp:SqlDataSource>
 
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" EnableAJAX="true" DefaultLoadingPanelID="RadAjaxLoadingPanel1">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="NamesDDL">

                <telerik:AjaxUpdatedControl ControlID="OrdersGrid" LoadingPanelID="AjaxLoadingPanel1"></telerik:AjaxUpdatedControl>
                <telerik:AjaxUpdatedControl ControlID="NamesDDL"></telerik:AjaxUpdatedControl>
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>
 
<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server">
</telerik:RadAjaxLoadingPanel>

Hi Zach,

The provided code looks correct. Could you confirm that the same issue persists when the combo and the grid are not in a widget?
