導出超鏈接字段在Excel未示出

我有一個顯示在asp.net柵格和與輸出相同場到Excel它後面C＃代碼另一個按鈕數據的按鈕。網格顯示數據源看起來如下：導出超鏈接字段在Excel未示出

<Columns> 
    <asp:BoundField HeaderText="Location" DataField="Location" SortExpression="Location" /> 
    <asp:BoundField HeaderText="Latitude" DataField="GPSLatitude" SortExpression="GPSLatitude" /> 
    <asp:BoundField HeaderText="Latitude" DataField="GPSLatitude" SortExpression="GPSLatitude" /> 
    <asp:BoundField HeaderText="Picture Link" DataField="PicLink" **Visible="true"**/> 
</Columns>

當我添加到PicLink，這是一個超級鏈接例如http://beta.example.co.za/trials/Pictures/V_2992.jpg屬性可見=「真」，該字段將顯示在數據網格視圖，並且還顯示Excel導出。如果我將Visible設置爲「false」，則數據網格和Excel導出都不顯示該字段。問題是我只想在Excel導出中顯示字段，但不是在數據網格上。

背後的C＃代碼 '導出到Excel' 按鈕，如下所示：

string attachment = "attachment; filename=ArchivedStuff.xls"; 

Response.ClearContent(); 
Response.AddHeader("content-disposition", attachment); 
Response.ContentType = "application/ms-excel"; 
StringWriter sw = new StringWriter(); 
HtmlTextWriter htw = new HtmlTextWriter(sw); 

gvLogDetails.AllowPaging = false; 
gvLogDetails.AllowSorting = false; 
string sort = ViewState["LogSortExpression"].ToString() + ' ' + ViewState["LogSortDirection"]; 
loadGrid(sort); 

GridView grdExport = new GridView(); 
grdExport.AllowPaging = false; 
grdExport.AllowSorting = false; 
grdExport.AutoGenerateColumns = false; 
grdExport = gvLogDetails; 

int colcount = grdExport.Columns.Count; 
for (int i = 1; i < colcount; i++) 
{ 
    grdExport.Columns[i].SortExpression = ""; 
} 

grdExport.Columns[0].Visible = false; 
grdExport.Columns[16].Visible = true; //the PicLink field 

//Prepare the grid for exporting to excell 
ExportToExcel.PrepareGridViewForExport(grdExport); 

// Create a form to contain the grid 
HtmlForm frm = new HtmlForm(); 

gvLogDetails.Parent.Controls.Add(frm); 
frm.Attributes["runat"] = "server"; 
frm.Controls.Add(grdExport); 
frm.RenderControl(htw); 
Response.Write(sw.ToString()); 

Response.End();

// ExportToExcel

public class ExportToExcel 
{ 
    #region Export to Excel 
    public static void PrepareGridViewForExport(Control gv) 
    { 
     Literal l = new Literal(); 

     for (int i = 0; i < gv.Controls.Count; i++) 
     { 
      if (gv.Controls[i].GetType() == typeof(LinkButton)) 
      { 
       l.Text = (gv.Controls[i] as LinkButton).Text; 

       gv.Controls.Remove(gv.Controls[i]); 
       gv.Controls.AddAt(i, l); 
      } 
      else if (gv.Controls[i].GetType() == typeof(HyperLink)) 
      { 
       l.Text = (gv.Controls[i] as HyperLink).Text; 

       gv.Controls.Remove(gv.Controls[i]); 
       gv.Controls.AddAt(i, l); 
      } 
      else if (gv.Controls[i].GetType() == typeof(DropDownList)) 
      { 
       l.Text = (gv.Controls[i] as DropDownList).SelectedItem.Text; 

       gv.Controls.Remove(gv.Controls[i]); 
       gv.Controls.AddAt(i, l); 
      } 
      else if (gv.Controls[i].GetType() == typeof(CheckBox)) 
      { 
       l.Text = (gv.Controls[i] as CheckBox).Checked ? "True" : "False"; 

       gv.Controls.Remove(gv.Controls[i]); 
       gv.Controls.AddAt(i, l); 
      } 
      else if (gv.Controls[i].GetType().Name == "DataControlLinkButton") 
      { 
       l.Text = (gv.Controls[i] as LinkButton).Text; 

       gv.Controls.Remove(gv.Controls[i]); 
       gv.Controls.AddAt(i, l); 
      } 

      if (gv.Controls[i].HasControls()) 
      { 
       PrepareGridViewForExport(gv.Controls[i]); 
      } 
     } 
    } 
    #endregion 
}

只有在Excel導出：

在gvLogDetails（我假設在aspx中）add

Visible="false"

第16列。您可以刪除

grdExport.AutoGenerateColumns = false;

並且您必須重新綁定數據。

您也可以直接使用gvLogDetails。
