<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" EnableAJAX="True">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="ProductionsModuleItemsMaster">

<UpdatedControls>

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

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadAjaxLoadingPanel runat="server" ID="RadAjaxLoadingPanel1"></telerik:RadAjaxLoadingPanel>

I added the above code to a user control auto-generated by the thunder wizard for adding a custom content type to a custom module; ModuleProject/Web/UI/<ContentType>sDetails.ascx

The RadGrid "ProductionsModuleItemsMaster" is not ajax-ified yet I enabled viewstate from backend pages and checked the box for including a script manager; the page does a full postback when interacting with the RadGrid, ProductionsModuleItemsMaster.

I then tried to programmatically attach the ajax setting to a standard button and it spit out something about a null value (the commented out line didnt work), so i manually created the ajax setting and it didnt encounter an error but the button is not ajax-ified:

protected override void OnInit(EventArgs e)

base.OnInit(e);

var setting = new AjaxSetting();

AjaxUpdatedControl target = new AjaxUpdatedControl(Button1.ID, RadAjaxLoadingPanel1.ID);

setting.UpdatedControls.Add(target);

setting.AjaxControlID = Button1.ID;

RadAjaxManager1.AjaxSettings.Add(setting);

//RadAjaxManager1.AjaxSettings.AddAjaxSetting(Button1, Button1, RadAjaxLoadingPanel1);

Without going into details, I resolved the issue by using this instead of radajaxmanger:

    public class CustomRadAjaxManager : RadAjaxManager

    

        protected override void OnInit(EventArgs e)

        

            this.Page.InitComplete += new EventHandler(Page_InitComplete);

        

        void Page_InitComplete(object sender, EventArgs e)

        

            base.OnInit(e);

Also, you'll need to set the enclosing div tag of the RadGrid to runat="server"
