Hello,

Try to change your AjaxSettings as shown below and see if it makes a difference.
ASPX:

<telerik:RadAjaxManager id="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSettings AjaxControlID="RadGrid1" >

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid1"></telerik:AjaxUpdatedControl>

</UpdatedControls>

</telerik:AjaxSettings>

</AjaxSettings>

</telerik:RadAjaxManager>

For more information, please refer to these articles:
