AJAX not starting until editmode is hit

[Tim]

I have a 3-level hierarchical grid with the inner-most table being updatable.  I have a combo-box that provides a filter to the grid.  So, the scenario is that I choose a filter and the grid re-binds.  I can then drill-down into the grid to the 3rd level and insert or update a record.

For some reason, I get full page postbacks when the grid refreshes after the combo-box filter is updated and when I click the plus signs to expand and drill down into the grid.  Once I reach a detail item and go into edit mode either through and update or insert, the page then seems to begin leveraging ajax instead of postbacks.

How can I force this behavior to work from the beginning?

I am developing a User Control that hosts the RadGrid in MOSS.

Masterpage includes:
<asp:ScriptManager runat="server" ID="ScriptManager1" />
 <WebPartPages:SPWebPartManager id="m" runat="Server"/>
 <telerik:RadAjaxManager runat="Server" ID="RadAjaxManager1"/>

UserControl includes:

<

telerik:RadAjaxManagerProxy ID="RadAjaxProxyManager1" runat="server">

 

 

<AjaxSettings>

 

 

<telerik:AjaxSetting AjaxControlID="RadComboBoxBudgetCenter">

 

 

<UpdatedControls>

 

 

<telerik:AjaxUpdatedControl ControlID="ButtonRefreshGrid"

 

 

LoadingPanelID="RadAjaxLoadingPanel1" />

 

 

<telerik:AjaxUpdatedControl ControlID="BOSummaryGrid"

 

 

LoadingPanelID="RadAjaxLoadingPanel1" />

 

 

</UpdatedControls>

 

 

</telerik:AjaxSetting>

 

 

<telerik:AjaxSetting AjaxControlID="ButtonRefreshGrid">

 

 

<UpdatedControls>

 

 

<telerik:AjaxUpdatedControl ControlID="ButtonRefreshGrid"

 

 

LoadingPanelID="RadAjaxLoadingPanel1" />

 

 

<telerik:AjaxUpdatedControl ControlID="BOSummaryGrid"

 

 

LoadingPanelID="RadAjaxLoadingPanel1" />

 

 

</UpdatedControls>

 

 

</telerik:AjaxSetting>

 

 

<telerik:AjaxSetting AjaxControlID="ButtonHideShowActuals">

 

 

<UpdatedControls>

 

 

<telerik:AjaxUpdatedControl ControlID="BOSummaryGrid" LoadingPanelID="RadAjaxLoadingPanel1" />

 

 

</UpdatedControls>

 

 

</telerik:AjaxSetting>

 

 

<telerik:AjaxSetting AjaxControlID="BOSummaryGrid">

 

 

<UpdatedControls>

 

 

<telerik:AjaxUpdatedControl ControlID="ButtonRefreshGrid"

 

 

LoadingPanelID="RadAjaxLoadingPanel1" />

 

 

<telerik:AjaxUpdatedControl ControlID="BOSummaryGrid"

 

 

LoadingPanelID="RadAjaxLoadingPanel1" />

 

 

</UpdatedControls>

 

 

</telerik:AjaxSetting>

 

 

</AjaxSettings>

 

 

</telerik:RadAjaxManagerProxy>

 

 

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Height="75px" Width="75px" Transparency="25">

 

 

<img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>' style="border:0;" />

 

 

</telerik:RadAjaxLoadingPanel>

 

Any ideas are appreciated.

Interestingly, this works as expected in Firefox but the original problem with postbacks still exists in Internet Explorer.

any ideas?

Thanks for your help!

Adding this script in the masterpage seems to have resolved the problem

<form runat="server" onsubmit="return _spFormOnSubmitWrapper();">
   <script type='text/javascript'>_spOriginalFormAction = document.forms[0].action; _spSuppressFormOnSubmitWrapper=true;</script>
<asp:ScriptManager runat="server" ID="ScriptManager1" />
 <telerik:RadAjaxManager runat="Server" ID="RadAjaxManager1"/>
