How To Make RadGrid AJAX Enabled.

[Umesh]

Hi All,

Iam using 2008.3.1314.35 version of RadControls for my application.
I want to make RadGrids AJAX enabled so that for every postback event it will work asynchronously.
But in this version RadGrid is not showing any property to do the same. 
Right now it is showing one property 'EnableAjaxSkinRendering'. 

I tried with setting this property to True,but still it is not giving me proper result.

I also  tried with by setting properties, 
EnableAJAX="True" EnableAJAXLoadingTemplate="True"

But RadGrid is not accepting these properties for this version.
Is there any way to do the same...?

Hello Umesh,

You can ajaxify your grid using the RadAjaxManager or RadAjaxPanel Controls. Refer to the following help documents to understand how to use either of these controls. Also, EnableAjax property of the grid is available only with RadGrid for Asp.Net version.
AJAX Manager
AJAX Panel


Thanks

Thanks Princy for your quick reply,
I have gone through AjaxManager,AjaxPanel.
But AjaxPanel updates all controls within it after any postback and for Ajax Manager we have to specify,
for which control we have to use Ajax by using design view.
I think these controls provides same functionality as Update Panel control of Ajax.
So Iam in confusion with what to use Update Panel control of AJAX or these provided controls.

Hello Umesh,

I recommend you examine the Advanages section of RadAjax in our documentation. I extracted several links below:

Hi Daniel,

I tried by using AjaxManager instead of Update Panel and It works really great.
But there is one issue over here.
Before completing one request i.e when it showing Loading image during asynchronous postback 
if I tried to make edit or add on radgrid for many times it is showing me error.
I think before completing one request it should not allow other request.
Also after using AjaxManager on page it is blocking popups which we are displaying for showing error  messages.

Is there any way to handle this.

Thanks...

Hello Umesh,

You can utilize the AJAX queue functionality of our RadAjaxManager:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" RequestQueueSize="3"...
