Load File .ASPX into DIV. In file .ASPX have a Gridview with Paging

When use this code

function HabilitaDiv(nomeDiv){

                                var div =  nomeDiv.replace("btn", "div").replace("menu", "div").replace("_", "");

                                $.ajax({

                                    method: "GET",
                                    url: "divAreaCliente.aspx",
                                    data: "div="+ div,
                                    beforeSend: function() {
                                        $("#carregando").show("fast");
                                    },
                                    complete: function() {
                                        $("#carregando").hide("slow");
                                    },
                                    success: function(conteudo) {
                                        $("#divTudo").html(conteudo);

                                    }

                                });

            }





















and click intothe page two of Gridview have a error: Error in time of execution of Microsoft JScript: 'theForm.__EVENTTARGET' is null or not object.
I test only ASPX.NET nothing Jquery and this Paging is correct, when i used Jquery is not Correct.
