使用此功能，并启用时寻呼=真

private void BindGrid(string sqlQuery, ref GridView gv)
{
    SqlConnection sqlConnection = null;
    try
    {
        sqlConnection = new SqlConnection(strConnect);
        SqlCommand scom = new SqlCommand(sqlQuery, sqlConnection);
        scom.CommandTimeout = 100;
        sqlConnection.Open();
        SqlDataAdapter adapter = new SqlDataAdapter(scom);
        DataTable dt = new DataTable();
        adapter.Fill(dt);
        gv.DataSource = dt;

Answer 1

添加处理程序PageIndexChanging事件。

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) 
 { 
  GridView1.PageIndex = e.NewPageIndex; 
  .....
  .....
  GridView1.DataSource=dt;
  GridView1.DataBind(); 
  }

Answer 2

尝试，此代码：

   int newPagenumber = e.NewPageIndex;
   GridView1.PageIndex = newPagenumber;

   GridView1.DataSource = call the method that will fill ur dataset.
   GridView1.DataBind();
