在ASP.NET Linq数据绑定中将Gridview数据导出到Excel

我使用波纹管代码导出gridview数据excel但问题是整个页面导出到excel.我只想要gridview数据而不是整页导出.怎么能解决这个问题？

HtmlForm form = new HtmlForm();
Response.Clear();
Response.Buffer = true;
string filename = "GridViewExport_" + DateTime.Now.ToString() + ".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);
gdvInBox.AllowPaging = false;
gdvInBox.DataBind();
form.Controls.Add(gdvInBox);
this.Controls.Add(form);
form.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();

提前致谢.

解决方法

设置excel导出非常容易,只导出gridview.这已经过测试,只会导出出现在给定网页上的gridview.

对于您的C#代码,请使用以下代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class vxcel_export : System.Web.UI.Page
{
    protected void Page_Load(object sender,EventArgs e)
    {
    }

    protected void Button2_Click(object sender,EventArgs e)
    {
        Response.Clear();
        response.addheader("content-disposition","attachment;filename=file-name.xls");
        Response.ContentType = "application/vnd.xlsx";
        System.IO.StringWriter stringWrite = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
        GridView1.RenderControl(htmlWrite);
        Response.Write(stringWrite.ToString());
        Response.End();
    }    

    public override void VerifyRenderingInServerForm(Control control)
    {
    }
}

在您的aspx代码中使用以下代码：

确保将EnableEventValidation =“false”添加到<％@ Page％>代码位于页面顶部.

将以下代码放在要将按钮导出gridview到Excel的位置：

<asp:Button ID="Button2" runat="server" OnClick="Button2_Click" Text="Whatever you want your button to say" />

您可以将高度和宽度修改为按钮中所需的任何大小.

而已.要记住的一件事是,在导出文件时,除非将其另存为工作簿/ Excel文件,否则它不是真正的Excel文件.
