發送選定的gridview列到excel文件

Question

我已經嘗試過將整個gridview數據保存到excel文件的代碼，它工作正常，但現在我想只保存gridview的特定列到excel文件。我已經使用mysql數據庫和asp.net與C＃。請任何人都幫助我。

**default.aspx** 
<asp:GridView ID="GridView1" runat="server"> 
    </asp:GridView> 

    <asp:Button ID="btnSave" runat="server" Text="Save to Excel" OnClick="btnSave_Click" /> 

**default.cs** 
protected void btnSave_Click(object sender, EventArgs e) 
    { 
     ExportGridToExcel(GridView1, "StudentMarks.xls"); 
    } 

    public void ExportGridToExcel(GridView grdGridView, string fileName) 
    { 
     Response.Clear(); 
     Response.AddHeader("content-disposition", string.Format("attachment;filename={0}.xls", fileName)); 
     Response.Charset = ""; 
     Response.ContentType = "application/vnd.xls"; 
     StringWriter stringWrite = new StringWriter(); 
     HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite); 
     grdGridView.RenderControl(htmlWrite); 
     Response.Write(stringWrite.ToString()); 
     Response.End(); 
    } 

    public override void VerifyRenderingInServerForm(Control control) 
    { 
     return; 
    } 

Answer 1

您可以用asp：BoundField的選擇要在GridView中顯示的列。然後將該gridview導出爲ex​​cel。 Ok。在你的情況下，你可以綁定一個新的gridview，但是沒有Edit/Delete列。您可以將這個新的gridview的可見性設置爲false。

生成Excel使用此方法..

protected void btnExportExcel_Click(object sender, EventArgs e) 
     { 
      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); 
      GridView.AllowPaging = false; 

      // Re-Bind data to GridView 

      using (MSEntities1 CompObj = new MSEntities1()) 
      { 
       // code for bind grid view 
       GridView.DataBind(); 
      } 

      // Change the Header Row back to white color 

      GridViewC.Style.Add(" font-size", "10px"); 

      GridView.HeaderRow.Style.Add("background-color", "#FFFFFF"); 


      //Apply style to Individual Cells 

      GridView.HeaderRow.Cells[0].Style.Add("background-color", "green"); 
      GridView.HeaderRow.Cells[1].Style.Add("background-color", "green"); 
      GridView.HeaderRow.Cells[2].Style.Add("background-color", "green"); 
      GridView.HeaderRow.Cells[3].Style.Add("background-color", "green"); 
      GridView.HeaderRow.Cells[4].Style.Add("background-color", "green"); 
      GridView.HeaderRow.Cells[5].Style.Add("background-color", "green"); 
      GridView.HeaderRow.Cells[6].Style.Add("background-color", "green"); 
      GridView.HeaderRow.Cells[7].Style.Add("background-color", "green"); 


      int k = GridView.Rows.Count; 

      for (int i = 1; i < GridView.Rows.Count; i++) 
      { 

       GridViewRow row = GridView.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"); 
        row.Cells[7].Style.Add("background-color", "#C2D69B"); 
       } 
      } 
      GridView.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(); 
     }
