ASP.net的GridView控件中的数据如何导入到Excel中～～～
第一中方法：
新建一个网站：在Default.aspx中写入下面代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>无标题页</title>
</head>
<body>
<form id="form1" runat="server">
<div>
</div>
<asp:GridView ID="GridView1" runat="server" >
</asp:GridView>
<asp:Button ID="BtnExport" runat="server" Text="导出" OnClick="Button1_Click" />
</form>
</body>
</html>
然后再在Default.aspx.cs中写入如下代码：
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.OleDb;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindData();
}
}
private void BindData()
{
OleDbConnection con = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=d:/db1.mdb");
OleDbDataAdapter thisadapter = new OleDbDataAdapter("select *from order by 房屋编号 asc", con);
string sql = "select *from 物管费用表 where 1=1";
thisadapter.SelectCommand.CommandText = sql;
DataSet ds = new DataSet();
con.Open();
thisadapter.SelectCommand.ExecuteNonQuery();
thisadapter.Fill(ds, "物管费用表");
this.GridView1.DataSource = ds;
this.GridView1.DataBind();
}
public override void VerifyRenderingInServerForm(Control control)
{
// Confirms that an HtmlForm control is rendered for
}
protected void BtnExport_Click(object sender, EventArgs e)
{
Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls");
Response.Charset = "gb2312";
Response.ContentType = "application/vnd.xls";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
GridView1.AllowPaging = false;
BindData();
GridView1.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();
GridView1.AllowPaging = true;
BindData();
}
protected void paging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
BindData();
}
}
第二中方法：
在Default.aspx中写入如下：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>Untitled Page</title>
</head>
<body id="Body1" runat="server">
<form id="form1" runat="server">
<div id="Div1" runat="server">
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="名称" DataSourceID="SqlDataSource1" AllowPaging="True"
BackColor="LightGoldenrodYellow" BorderColor="Tan" BorderWidth="1px"
CellPadding="2" ForeColor="Black" GridLines="None" >
<FooterStyle BackColor="Tan" />
<Columns>
<asp:BoundField DataField="名称" HeaderText="名称" />
<asp:BoundField DataField="结构" HeaderText="结构" />
<asp:BoundField DataField="建筑面积" HeaderText="建筑面积" />
<asp:BoundField DataField="层数" HeaderText="层数" />
<asp:BoundField DataField="房屋数量" HeaderText="房屋数量" />
<asp:BoundField DataField="单元数量" HeaderText="单元数量" />
<asp:BoundField DataField="施工单位" HeaderText="施工单位" />
<asp:BoundField DataField="竣工日期" HeaderText="竣工日期" />
</Columns>//上面这些DataField都是数据库表中添加到字段名
<PagerStyle BackColor="PaleGoldenrod" ForeColor="DarkSlateBlue"
HorizontalAlign="Center" />
<SelectedRowStyle BackColor="DarkSlateBlue" ForeColor="GhostWhite" />
<HeaderStyle BackColor="Tan" Font-Bold="True" />
<AlternatingRowStyle BackColor="PaleGoldenrod" />
</asp:GridView>
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="导出" />
<br />
</div>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:db1ConnectionString3 %>"
SelectCommand="SELECT [ID], [名称], [结构], [建筑面积], [层数], [备注], [竣工日期], [施工单位], [单元数量], [房屋数量] FROM [小区楼宇信息表]" ProviderName="<%$ ConnectionStrings:db1ConnectionString3.ProviderName %>"></asp:SqlDataSource>
</form>
</body>
</html>
然后再在Default.aspx.cs中写入下面代码：
using System;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DataBind();//绑定数据
}
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Clear();
System.Web.HttpContext curContext = System.Web.HttpContext.Current;
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls");
Response.Charset = "UTF-8";//设置字符集
curContext.Response.ContentEncoding = System.Text.Encoding.UTF8;//设置编码集
Response.ContentType = "application/vnd.xls";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
GridView1.AllowPaging = false;//写到Excel的数据不用分页
BindData();
GridView1.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());//向客户端写数据
Response.End();
GridView1.AllowPaging = true;//恢复分页
BindData();
}
private void BindData()
{
GridView1.DataBind();
}
public override void VerifyRenderingInServerForm(Control control)//这个方法不写的话可能报错类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内。
{
// Confirms that an HtmlForm control is rendered for
}
}
当然还有其他的方法，在此就介暂时给大家介绍这2种了～
