string strCon = \北风贸易;Uid=sa;Pwd=\ protected void Page_Load(object sender, EventArgs e) {

if (!IsPostBack) {

ViewState[\身份证号码\ ViewState[\ bind(); } }

protected void GridView1_Sorting(object sender, GridViewSortEventArgs e) {

string sPage = e.SortExpression;

if (ViewState[\ {

if (ViewState[\ ViewState[\ else

ViewState[\ } else {

ViewState[\ } bind(); }

public void bind() {

string sqlstr = \飞狐工作室\ sqlcon = new SqlConnection(strCon);

SqlDataAdapter myda = new SqlDataAdapter(sqlstr, sqlcon); DataSet myds = new DataSet(); sqlcon.Open();

myda.Fill(myds, \飞狐工作室\

DataView view = myds.Tables[\飞狐工作室\ string sort = (string)ViewState[\

(string)ViewState[\ view.Sort = sort;

GridView1.DataSource = view; GridView1.DataBind(); sqlcon.Close(); } }
