[Solved] Script Control may not be registered before prerender

[Subbaraya Prabu]

Hi, 
I am using RadGrid and I have  added the  scriptmanager to the page from code, making sure that the  first control on the  form is  always a scriptmanager. However, while loading the  page it works fine but  on postback it  throws the  error "Script Control may not be  registered before prerender". 

 Stack Trace: 

[InvalidOperationException: Script controls may not be registered before PreRender.]

I have  used the  control as follows. 

 <radg:RadGrid CssClass="grid_container" ID="grdProperties" runat="server" EnableAJAX="true"
                                HeaderStyle-Wrap="false" BorderWidth="1" BorderColor="#cccccc" ItemStyle-Wrap="false"
                                AlternatingItemStyle-Wrap="false" AutoGenerateColumns="False" CellSpacing="0"
                                CellPadding="0" GridLines="None" AllowSorting="True" EnableEmbeddedSkins="false" EnableAjaxSkinRendering="false" EnableEmbeddedBaseStylesheet="false"> 
                                <ItemStyle CssClass="grid" BorderWidth="0" />
                                <AlternatingItemStyle CssClass="grid_alt" BorderWidth="0"></AlternatingItemStyle>
                                <HeaderStyle CssClass="grvHeadings"></HeaderStyle>
                                <MasterTableView BorderWidth="0" AutoGenerateColumns="false" ItemStyle-CssClass="grid"
                                    ItemStyle-BorderWidth="1" AlternatingItemStyle-CssClass="grid_alt" BorderColor="#cccccc">
                                    <Columns>
                                        <radg:GridTemplateColumn HeaderStyle-Wrap="false" ItemStyle-HorizontalAlign="Right"
                                            HeaderStyle-HorizontalAlign="Right" HeaderStyle-CssClass="grvHeadings" ItemStyle-Wrap="false"
                                            ItemStyle-BorderWidth="0">
                                            <HeaderTemplate>
                                            </HeaderTemplate>
                                            <ItemTemplate>
                                            </ItemTemplate>
                                        </radg:GridTemplateColumn>
 </Columns>
                   </MasterTableView>
            </radg:RadGrid>
 Could you guide me as how I could  handle this exception. 

Thanks in Advance.
