Hi Warren,

I would also need to see your AjaxSettings in order to see your idea of ajaxifying the controls in your page. I see that you also have a master page and I assume the settings are presented in it, so it would be helpful if you share that part as well.

My suggestion is that you send us the full code for the pages related to the problemmatic scenario in a formal support ticket, so we can run a test page using your logic and inspect the behavior of the ajaxified controls locally.

Hi Warren,

The first thing which I noticed is that you have set RadAjaxManager as AJAX initiator for all grids in the page. This would mean that on any AJAX request on the page, these five RadGrid controls will be updated, thus including the callback to refresh the other controls they are set up to update, so this results in most of the page being updated.

Could you please remove this setting from the manager's set up and see if the undesired behavior persists?

<telerik:AjaxSetting AjaxControlID="RadAjaxManager1">

<UpdatedControls>

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

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

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

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

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