从GridView导出数据到Excelsheet时如何删除Excel表格中的分页文本？

Question

我在asp.net应用程序中实现了导出到excel的功能。这里我将数据从网格视图导出到excel表。我还在网格视图中应用了分页。

因此，当我将数据从网格视图导出到 Excel 工作表时，分页文本也会显示在 Excel 工作表中，如给定图像所示。

我们如何删除它

我遵循以下方法导出数据

代码隐藏：

Response.Clear()
Response.ClearHeaders()
Response.AddHeader("content-disposition", "attachment;filename=sample.xls")
Response.Charset = ""
Response.ContentType = "application/vnd.xls"

Dim sb As StringBuilder = New StringBuilder()
Dim objStringWriter As StringWriter = New StringWriter(sb)
Dim objHtmlTextWriter As HtmlTextWriter = New HtmlTextWriter(objStringWriter)

//gvSample is Gridview server control
gvSample.RenderControl(objHtmlTextWriter)

Response.ContentEncoding = Encoding.Unicode
Response.BinaryWrite(System.Text.Encoding.Unicode.GetPreamble())
Response.Write(objStringWriter)
Response.End()

谢谢

Answer 1

渲染前 - 禁用分页，绑定数据然后渲染：

 gvSample.AllowPaging = false;
 gvSample.DataSource = ds; //Data Source
 gvSample.DataBind();
 gvSample.RenderControl(objHtmlTextWriter)

Answer 2

每当从数据库获取数据以显示 gridview 时，在此之前，但在重用它之后，结果内容会在 viewstate[""] 中。当搜索数据以过滤主要内容时，更新的数据将显示在视图状态中，因此您将获得要导出的正确数据

gvSample.AllowPaging = false;
gvSample.DataSource = ViewState["vsData"]; //Data Source
gvSample.DataBind();
gvSample.RenderControl(objHtmlTextWriter);

Answer 3

它可以使用 SQL DataSourceID 来工作

using (StringWriter sw = new StringWriter())
{

  HtmlTextWriter hw = new HtmlTextWriter(sw);
  //To Export all pages
  GridView1.AllowPaging = false;

  GridView1.DataBind();


  GridView1.HeaderRow.BackColor = Color.White;
  foreach (TableCell cell in GridView1.HeaderRow.Cells)
  {
    cell.BackColor = GridView1.HeaderStyle.BackColor;
  }
  foreach (GridViewRow row in GridView1.Rows)
  {
    row.BackColor = Color.White;
    foreach (TableCell cell in row.Cells)
    {
      if (row.RowIndex % 2 == 0)
      {
      cell.BackColor = GridView1.AlternatingRowStyle.BackColor;
      }
      else
      {
        cell.BackColor = GridView1.RowStyle.BackColor;
      }
    cell.CssClass = "textmode";
  }
}

GridView1.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();

其他附加的asp编码文件

 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes["ondblclick"] = Page.ClientScript.GetPostBackClientHyperlink(GridView1, "Edit$" + e.Row.RowIndex);
            e.Row.Attributes["style"] = "cursor:pointer";
        }
    }
