Ajax not working after upgrade 2010.2.929.35

[Ted]

I upgraded a project to the latest version 2010.2.929.35 and I had Radcombobox that when changed updated a grid with a Linqdatasource but now changing the combobox won't refresh the grid.  any thoughts on what may have happened?

this is in my masterpage

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">
        <Scripts>
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
            <asp:ScriptReference Path="Scripts/SessionKeepalive.js" />
        </Scripts>
    </telerik:RadScriptManager>
    <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    </telerik:RadAjaxManager>

 

 

 

this is the combobox
 

 

<telerik:RadComboBox ID="_Stage" runat="server" AutoPostBack="True"
                    onselectedindexchanged="_Stage_SelectedIndexChanged">
                    <Items>
                        <telerik:RadComboBoxItem runat="server" Text="Pre-Proposal" Value="Pre-Proposal" />
                        <telerik:RadComboBoxItem runat="server" Text="Proposal" Value="Proposal" />
                        <telerik:RadComboBoxItem runat="server" Text="Active" Value="Active" />
                    </Items>
                </telerik:RadComboBox>

 

 

 

grid header
 

 

<telerik:RadGrid ID="_opps" runat="server" DataSourceID="LinqDataSource1"
            GridLines="None" AllowFilteringByColumn="True" AllowSorting="True"
        Width="1600px" onitemdatabound="_opps_ItemDataBound"
        onexcelmlexportrowcreated="RadGrid1_ExcelMLExportRowCreated"
        onexcelmlexportstylescreated="RadGrid1_ExcelMLExportStylesCreated"
        onitemcommand="_opps_ItemCommand"
        onitemcreated="_opps_ItemCreated" >
            <ExportSettings ExportOnlyData="True" IgnorePaging="True"
                OpenInNewWindow="True">
                <Excel Format="ExcelML" />
            </ExportSettings>
<MasterTableView AutoGenerateColumns="False" DataSourceID="LinqDataSource1"
                DataKeyNames="OPPORTUNITYID" UseAllDataFields="True">

 

 

 

 

LinqDatasource where parameters
 

<WhereParameters>
                    <asp:ControlParameter ControlID="_Stage" Name="STAGE"
                        PropertyName="SelectedValue" Type="String" />
                    <asp:ControlParameter ControlID="_Type" Name="TYPE"
                        PropertyName="SelectedValue" Type="String" />
                </WhereParameters>

 

I setup the ajax using

private object Content(string id)
{
   return Page.Master.FindControl(id);
}
protected void Page_Load(object sender, EventArgs e)
{
   AjaxManager.AjaxSettings.AddAjaxSetting(_opps, _opps);
   AjaxManager.AjaxSettings.AddAjaxSetting(_opps, _number);
}

OK.  never mind.  I just had to specifically tell it what loading panel to use where before I didn't have too.  Not sure if that is considered a bug or not but it works as long as I specify the Loading panel to use.

Actually the Ajax call was working before, I just wasn't seeing the Loading panel so I didn't think that it was working.
