Bind AjaxManager to Specific Events

[ataxia1]

For demonstration-sake, let's say we have two controls, a RadCalendar and a RadScheduler.  In order for them to interact with one-another without a refresh, the AjaxManager binds them together.

Unless I'm mistaken, this means any action on either must take the time to update both.  For example, navigating months (without selecting) on the calendar, which should be a very fast operation, takes a long time because the RadSheduler is being re-rendered as well, even though no changes have been made.

Is there a way to bind only specific events together, similar to how the VS.net AjaxManager works ControlID="" EventName=""?  This would allow the Scheduler to be rendered again, only on applicable events.

Thanks,

Brad

Hello Ataxia1,

Yes, it is possible to do what you are asking. In the AjaxSetting of your RadAjaxManager, simply set the EventName property to the event you'd like the update to depend on. You can add multiple AjaxSettings to further customize the events and controls that cause updates.

Here is a simple example of a RadCalendar that updates itself on any postback, and updates itself and the RadScheduler on the OnSelectionChanged event.

	<telerik:RadScriptManager ID="RadScriptManager1" runat="server" />
	<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
	<AjaxSettings>
	<telerik:AjaxSetting AjaxControlID="RadCalendar1" EventName="OnSelectionChanged">
	<UpdatedControls>
	<telerik:AjaxUpdatedControl ControlID="RadCalendar1"  />
	<telerik:AjaxUpdatedControl ControlID="RadScheduler1"  />
	</UpdatedControls>
	</telerik:AjaxSetting>
	<telerik:AjaxSetting AjaxControlID="RadCalendar1">
	<UpdatedControls>
	<telerik:AjaxUpdatedControl ControlID="RadCalendar1"  />
	</UpdatedControls>
	</telerik:AjaxSetting>
	</AjaxSettings>
	</telerik:RadAjaxManager>
	<telerik:RadCalendar ID="RadCalendar1" runat="server"
	AutoPostBack="true"
	OnSelectionChanged="RadCalendar1_SelectionChanged">
	</telerik:RadCalendar>
	<telerik:RadScheduler ID="RadScheduler1" runat="server"
	DataKeyField="ID"
	DataSubjectField="Subject"
	DataStartField="Start"
	DataEndField="End">
	</telerik:RadScheduler>

I hope this helps. If you continue have trouble, please let me know.

Hi Kevin,

I've been searching for this info for past  many hours. This is great.

I just need one info, I need to use this with RadScheduler - Where can I find  the list of Eventnames of RadScheduler.

Many thanks

I know this is an old post, but I was wondering if It's possible to do this with the radcalendar and the radscheduler in different usercontrols on the same page?
