Hello,

I have tried to reproduce the same but no avail. Here is the code.
ASPX:

<telerik:RadAjaxPanel ID="RadAjaxManager1" runat="server" ClientEvents-OnRequestStart="requestStart" ClientEvents-OnResponseEnd="responseEnd">

<asp:Button ID="Button1" runat="server" Text="abc" />

</telerik:RadAjaxPanel>

JS:

<script type="text/javascript">

function requestStart(sender, eventArgs)

{

alert('Request start');

}

function responseEnd(sender, eventArgs)

{

alert('Response complete');

}

</script>

Thanks,
Princy.

Hello Asif,

I have created sample project to illustrate the approach you need to use in order to successfully hook the RequestStart and ResponseEnd client events of RadAjaxPanel.

Give this project a try and check what are the differences with yours.

Hello Asif,

I created a project with your pages but again it is working as expected on my side. I have made a video for you to see how things are going on my side.

You could check the Visual Studio settings, restart the ASP.NET Development server, it seems to me that the problem is in the Visual Studio.

You could try to clear the content of these folders:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files and

C:\Users\current_user\AppData\Local\Microsoft\VisualStudio\10.0\ProjectAssemblies

and to check whether this helps.

All the best,

Hi,

Ajax requests could be only performed by controls that implement IPostaBackContainer interface. Basically you want to update one control based on another input control like button, checkbox, dropdown, etc. What will be in the TR and TD elements and what they need to update when the response come back from the server?

</Radajaxpanel>

Hi,

TR and TD tags are HTML tags and does not have any server-side or client-side functionality, so they are could not affect the Ajax calls in no way. I made a sample project to verify this behavior. You could find it attached to my post.
