導出Gridview到Excel：無法導出正確的數據顯示

Question

我需要將我的gridview數據導出爲ex​​cel。這沒有問題。 所有工作正常 問題是我可以應用篩選器顯示在網格中的數據。當我只想導出這些數據時（一旦應用了過濾器），它會在過濾器之前導出之前包含在我的網格中的所有數據。

我希望我足夠清楚......

這是我使用的代碼：

public void ExportGridToExcel(GridView grdGridView, string fileName) 
    { 
     Response.Clear(); 
     Response.Buffer = true; 

     Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.xls"); 
     Response.Charset = ""; 
     Response.ContentType = "application/vnd.ms-excel"; 
     StringWriter sw = new StringWriter(); 
     HtmlTextWriter hw = new HtmlTextWriter(sw); 

     grdGridView.AllowPaging = false; 
     grdGridView.DataBind(); 

     //Change the Header Row back to white color 
     grdGridView.HeaderRow.Style.Add("background-color", "#FFFFFF"); 

     // Apply style to Individual Cells 
     grdGridView.HeaderRow.Cells[0].Style.Add("background-color", "green"); 
     grdGridView.HeaderRow.Cells[1].Style.Add("background-color", "green"); 
     grdGridView.HeaderRow.Cells[2].Style.Add("background-color", "green"); 
     grdGridView.HeaderRow.Cells[3].Style.Add("background-color", "green"); 
     grdGridView.HeaderRow.Cells[4].Style.Add("background-color", "green"); 
     grdGridView.HeaderRow.Cells[5].Style.Add("background-color", "green"); 
     grdGridView.HeaderRow.Cells[6].Style.Add("background-color", "green"); 

     for (int i = 0; i < grdGridView.Rows.Count; i++) 
     { 
      GridViewRow row = grdGridView.Rows[i]; 

      // Change Color back to white 
      row.BackColor = System.Drawing.Color.White; 
      // Apply text style to each Row 
      row.Attributes.Add("class", "textmode"); 
      // Apply style to Individual Cells of Alternating Row 
      if (i % 2 != 0) 
      { 
       row.Cells[0].Style.Add("background-color", "#C2D69B"); 
       row.Cells[1].Style.Add("background-color", "#C2D69B"); 
       row.Cells[2].Style.Add("background-color", "#C2D69B"); 
       row.Cells[3].Style.Add("background-color", "#C2D69B"); 
       row.Cells[4].Style.Add("background-color", "#C2D69B"); 
       row.Cells[5].Style.Add("background-color", "#C2D69B"); 
       row.Cells[6].Style.Add("background-color", "#C2D69B"); 
      } 
     } 
     grdGridView.RenderControl(hw); 

     // style to format numbers to string 
     string style = @"<style> .textmode { mso-number-format:\@; } </style>"; 
     Response.Write(style); 
     Response.Output.Write(sw.ToString()); 
     Response.Flush(); 
     Response.End(); 
    } 

我做什麼應用過濾器（所有的作品完美）

public void refreshGridFactures() 
    { 
     DateTime? debutFacture = null; 
     DateTime? FinFacture = null; 
     DateTime? DebutReglement = null; 
     DateTime? FinReglement = null; 
     int? NumeroFacture = 0; 

     if (PickerDateDebut.SelectedDate != null) { debutFacture = PickerDateDebut.SelectedDate; } 
     if (PickerDateFin.SelectedDate != null) { FinFacture = PickerDateFin.SelectedDate; } 
     if (PickerDebutReglement.SelectedDate != null) { DebutReglement = PickerDebutReglement.SelectedDate; } 
     if (PickerFinReglement.SelectedDate != null) { FinReglement = PickerFinReglement.SelectedDate; } 
     int IdEntreprise = Convert.ToInt32(ddlEntreprises.SelectedValue); 
     string Intitule = txtIntitule.Text; 
     if (txtNumeroFacture.Text != "") { NumeroFacture = Convert.ToInt32(txtNumeroFacture.Text); } 

     List<DBAccess.Facturation> listFacturation = DBAccess.DAOFacturation.GetFactures(IdEntreprise, debutFacture, FinFacture, DebutReglement, FinReglement, Intitule, NumeroFacture); 
     GridFactures.DataSource = listFacturation; 
     GridFactures.DataBind(); 

     double total = Math.Round(listFacturation.Sum(a => a.MontantTTC), 2); 
     double totalHT = Math.Round(listFacturation.Sum(a => a.MontantHT), 2); 

     lblTotalTTC.Text = "Montant total TTC : " + total; 
     lblTotalHT.Text = "Montant total HT : " + totalHT; 
    } 

感謝您的幫助

緊隨您的GridViewRow row = grdGridView.Rows[i];添加一個檢查，看看是否該行可見

if(!row.Visible) continue;
