I have a grid that is working fine, the problem is, when I put it inside RadAjaxPanel, I click 
add new record, the insert open successfully, I enter the values and click insert the RadGrid_InsertCommand
does not get invoked, and the grid shows empty again...

When I remove it from RadAjaxPanel it works normally..

Any pointers to this behavior ??

Hi Rabeeh ,

The RadGrid control is properly configured. However can you share the full page code plus the code behind file for further research?

Also, please check any javascript errors are thrown on the page.

Kind regards,

In the code behind, the grid is binded to a data table stored in session. This grid is located in a web control, and this web control is located in Rad Tab control in another page. there is Rad Script manager and style sheet manager on this page...

I created another example where I put only one grid and bind it to Linq data source, I enable automatic CRUD commands on grid and data source, I enable ajax, each time I add record it does not add, and it does not update, I remove ajax and all works fine, here is the a sample of the code, I refereed to any entity in linq context.

<telerik:RadScriptManager ID="RadScriptManager1" Runat="server">

Hello Rabeeh ,

I can see that you are ajaxifying the grid with the RadAjaxManager control but you have one additional RadAjaxPanel around the grid. Can you see if removing the odd RadAjaxPanel makes any difference?

All the best,
