                                        <tr>
                                            <td style="width: 200px;">
                                                <asp:Button ID="Button1" runat="server" OnClientClick="changePage('first'); return false;"

Hi...
i solved this by changing some javascript.

initially my page change function was :

	function changePage(argument)
	{
	tableView.page(argument);
	}

then i changed it to

	function changePage(argument)
	{
	if(!(argument=='next' && tableView.get_currentPageIndex()+1==tableView.get_pageCount()))
	tableView.page(argument);
	}

now it works fine...
but if it is RadGrid problem, it should be soulved...

Thanks...
