RadGrid, Custom Paging and Ajax -- Oh My!

[Tracy]

I have a RadGrid that is populated from an object DataSource (bound in code-behind). I have the sutom pagin all working except it is posting back instead of making the paging call through Ajax. I have a RadAjaxManager on the page that sets the AjaxUpdatedControl to the RadGrid and I even have a RadAjaxLoadingPanel set up and have tol the AjaxManager to use that as it's Default Loading Panel. What am I missing. I've read all the examples (most of which are old enough that they don't use the RadAjaxManager or the RadAjaxLoadingPanel.

Any help will be appreciated.

Hello Tracy,

Can you post the manager declaration?

I have tried several different incarnations of the Ajax Manager code, this is how it currently looks.

<telerik:RadAjaxManager ID="AjaxManager" runat="server" DefaultLoadingPanelID="LoadingPanel" EnableAJAX="true">
  <AjaxSettings>
    <telerik:AjaxSetting AjaxControlID="AjaxManager">
        <UpdatedControls>
            <telerik:AjaxUpdatedControl ControlID="UserRadGrid" />
        </UpdatedControls>
    </telerik:AjaxSetting>
  </AjaxSettings>
</telerik:RadAjaxManager>

Thanks for the help.

Hi Lee,

You need to select the grid to update itself:

<telerik:RadAjaxManager ID="AjaxManager" runat="server" DefaultLoadingPanelID="LoadingPanel" EnableAJAX="true"> 
  <AjaxSettings>
    <telerik:AjaxSetting AjaxControlID="UserRadGrid"> 
        <UpdatedControls>
            <telerik:AjaxUpdatedControl ControlID="UserRadGrid" />
        </UpdatedControls>
    </telerik:AjaxSetting>
  </AjaxSettings>
</telerik:RadAjaxManager>

That is how I had it set up originally based on the live demos. That still does a post back. Any other ideas?

It seems the problem stems from the fact that I am loading the RadScriptManager progrmatically. I have tried it OnPageLoad and OnInit. I need to load it in the master page (Because I have a PanelBar menu there that needs it.) but I don't want it on the login page, because it throws 'Sys is undefined' errors when I do. So in my Page_Load (or OnInit) I was loading like so:

if(Page.User.Identity.IsAuthenticated)
  Page.Form.Controls.Add(new RadScriptManager());

Loading the RadScriptManager from the code-behind doesn't seem to work.

Is there a more efficient way to set up the RadScriptManager?

I have fixed the problem. I switched the RadScriptManager out for an asp ScriptManager and all is well. I can put it in the .aspx page and it does not interfere with my login page or my panelbar and is available for all pages using that master page.

Thanks for all your help.
