GridView 分頁後，SelectedIndexChanging 資料綁定錯誤

摘要:GridView 分頁後，SelectedIndexChanging 資料綁定錯誤

今天又抓到一隻前輩留下來的蟲，錯誤發生在當GridView點選分頁後，不管點選哪個選項都只會出現第一頁的分頁資料，看了一下，原來是算錯index了!!!

原本的程式碼:

   1:  protected void GridViewRC_PageIndexChanging(object sender, GridViewPageEventArgs e)

   2:        {

   3:             List rcs = (List) Session["EditRCs"];

   4:             this.GridViewRC.PageIndex = e.NewPageIndex;

   5:             bindRCGridView(rcs);

   6:         }

7:

   8:  protected void GridViewRC_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)

   9:         {

  10:             List rcs = (List)Session["EditRCs"];

  11:             BSMDSS.BFSM.SMEC.CNR.Web.WRRC.RC rc = rcs[e.NewSelectedIndex];

  12:             Session.Add("EditRC", rc);

  13:             Response.Redirect("~/RC/FRMEditRC.aspx");

  14:         }

修改後的程式碼:

   1:  protected void GridViewRC_PageIndexChanging(object sender, GridViewPageEventArgs e)

   2:         {

   3:             List rcs = (List) Session["EditRCs"];

   4:             this.GridViewRC.PageIndex = e.NewPageIndex;

   5:             bindRCGridView(rcs);

   6:         }

7:

   8:  protected void GridViewRC_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)

   9:         {

  10:             List rcs = (List)Session["EditRCs"];

  11:             BSMDSS.BFSM.SMEC.CNR.Web.WRRC.RC rc = rcs[e.NewSelectedIndex+GridViewRC.PageIndex*GridViewRC.PageSize];

  12:             Session.Add("EditRC", rc);

  13:             Response.Redirect("~/RC/FRMEditRC.aspx");

  14:         }
