public partial class Manage_AdminNews : System.Web.UI.Page
{
  BaseClass bc = new BaseClass();
  protected void Page_Load(object sender, EventArgs e)
  {
  if (!IsPostBack) 
  {
  GridView1_Bind();
  }

  }
  protected void GridView1_Bind() 
  {
  GridView1.DataSource = bc.GetDateSet("select ID,NewsTitle,AddTime from News order by UPDateTime desc", "News");
  GridView1.DataKeyNames = new string[] { "ID" };
  GridView1.DataBind();
  }
   
  protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
  {
  GridView1.PageIndex = e.NewPageIndex;
   
  GridView1.DataBind();
  }
  protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
  {
  }

}

------解决方案--------------------------------------------------------
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) 
{ 
GridView1.PageIndex = e.NewPageIndex; 

GridView1.DataBind(); 
} 

GridView1.DataBind(); 这个方法改成GridView1_Bind() ；
