Why is Ajax happening when not set up?

[Lenny_shp]

2009.3.1503.35
I have a main page with AjaxMgr, and that loads the user control.

<div id="divPlaceHolder" runat="server" >
     <asp:PlaceHolder ID="myPlaceHolder" runat="server"></asp:PlaceHolder>
</div>

I do not have Ajax set up from myPlaceHolder to myPlaceHolder, or divPlaceHolder to divPlaceHolder.
I do have a menu on the main page to updates divPlaceHolder so it shows the User Control.

<telerik:AjaxSetting AjaxControlID="mnuFunction">
    <UpdatedControls>
          <telerik:AjaxUpdatedControl ControlID="divPlaceHolder" />
    </UpdatedControls>
</telerik:AjaxSetting>

However in the user control (I do not have AjaxMgrProxy set up), if there is autopostback in its child control, it'll do an Ajax update.

Is that expected?   I would have assumed that I have to use AjaxMgrProxy to set up Ajax within User Control but it seems to be doing that by its own?

Hi Lenny_shp,

The described behavior is expected. Because when a controls is ajaxified with RadAjax and updated via ajax, an ajax panel is wrapped around it.
To overcome that behavior you can handle the RadAjaxManager AjaxSettingsCreated event as shown below:

void manager_AjaxSettingCreated(object sender, AjaxSettingCreatedEventArgs e)
{
    if (e.Updated == divPlaceHolder)
    {
        e.UpdatePanel.ChildrenAsTriggers = false;
    }
}

Thanks, could this be a property of AjaxSetting for future?

<telerik:AjaxSetting AjaxControlID="cboxyz"  ChildrenAsTriggers="false">

Hi Lenny_shp,

Indeed, this is a good idea and I will share it with our developers so they could check it out and consider implementing such a property.
