将Gridview导出为ex​​cel而不使用网格线

标签： c# excel gridview export asp.net-2.0

我使用此代码将datagridview导出为ex​​cel 

HtmlForm form = new HtmlForm();
Response.Clear();
Response.Buffer = true;
string fileName = "TRAIL" + "[" + DatefromTxtBox.Text.Replace("/", "") + "_" + DatetoTxtBox.Text.Replace("/", "") + "]" + ".xls";
Response.AddHeader("content-disposition", "attachment;filename=" + fileName);
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
AuditTrailGV.AllowPaging = false;
AuditTrailGV.DataSource = (DataSet)ViewState["audit"];
AuditTrailGV.DataBind();
form.Controls.Add(AuditTrailGV);
this.Controls.Add(form);
form.RenderControl(hw);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();

问题是此代码还捕获了gridview的格式/边框

以下是示例屏幕截图

这是我在asp.net中的gridview enter image description here

这就是我的出色表现 enter image description here

你可以看到它改变了所有的行，比如gridview，我不希望它发生，如果我只能保留仅包含数据的行的网格线，如果不可能，则删除全部网格线..

任何帮助？我真的不喜欢我的excell中的那些网格线

VB 

Public Overrides Sub VerifyRenderingInServerForm(control As Control)
    'base.VerifyRenderingInServerForm(control);
    'This remains empty
End Sub

Protected Sub btnExcel_Click(sender As Object, e As ImageClickEventArgs) Handles btnExcel.Click

    Response.Clear()
    Response.AddHeader("content-disposition", "attachment;filename=FileName.xls")
    Response.Charset = ""
    Response.Cache.SetCacheability(HttpCacheability.NoCache)
    Response.ContentType = "application/vnd.ms-excel"

    Dim stringWrite As New System.IO.StringWriter()

您可以尝试以下代码并自定义下载数据的颜色。除了数据之外，它也不会对Column和行进行着色。

protected void DownloadExcel_Click(object sender, EventArgs e)
{
    Response.ClearContent();
    Response.Buffer = true;
    Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "Report.xls"));
    Response.ContentType = "application/ms-excel";
    StringWriter sw = new StringWriter();
    HtmlTextWriter htw = new HtmlTextWriter(sw);
    GridView1.AllowPaging = false;
    GridView1.DataBind();
    GridView1.HeaderRow.Style.Add("background-color", "#FFFFFF");

    for (int i = 0; i < GridView1.HeaderRow.Cells.Count; i++)
    {
        GridView1.HeaderRow.Cells[i].Style.Add("background-color", "#bfc2c7");
    }

    int j = 1;
    foreach (GridViewRow gvrow in GridView1.Rows)
    {           
        //gvrow.BackColor = color.White;
        if (j <= GridView1.Rows.Count)
        {
            if (j % 2 != 0)
            {
                for (int k = 0; k < gvrow.Cells.Count; k++)
                {
                    gvrow.Cells[k].Style.Add("background-color", "#EFF3FB");    
                }
            }
        }
        j++;
    }
    GridView1.RenderControl(htw);
    Response.Write(sw.ToString());
    Response.End();
}
