首先要把GridView控件放到panel中
AutoGenerateColumns="False" AllowPaging="True" AllowSorting="True" OnRowDeleting="gridview1_RowDeleting"
OnRowEditing="gridview1_RowEditing" DataKeyNames="sno" OnDataBound="gridview1_DataBound"
Font-Size="14px">
DataNavigateUrlFormatString="StudentInfo.aspx?id={0}" />
再添加一个按钮，用于触发导出事件：
以上为aspx页面代码，后台代码则是：
protected void lbtnexcel_Click(object sender, EventArgs e)
{
gridview1.BottomPagerRow.Visible = false;//导出到Excel表后，隐藏分页部分
gridview1.Columns[9].Visible = false;//隐藏“编辑”列
gridview1.Columns[10].Visible = false;//隐藏“删除”列
DateTime dt = DateTime.Now;//给导出后的Excel表命名，结合表的用途以及系统时间来命名
string filename = dt.Year.ToString() + dt.Month.ToString() + dt.Day.ToString() + dt.Hour.ToString() + dt.Minute.ToString() + dt.Second.ToString();
/*如导出的表中有某些列为编号、身份证号之类的纯数字字符串，如不进行处理，则导出的数据会默认为数字，例如原字符串"0010"则会变为数字10，字符串"1245787888"则会变为科学计数法1.236+E9，这样便达不到我们想要的结果，所以需要在导出前对相应列添加格式化的数据类型，以下为格式化为字符串型*/
foreach (GridViewRow dg in this.gridview1.Rows)
{
dg.Cells[0].Attributes.Add("style", "vnd.ms-excel.numberformat: @;");
dg.Cells[5].Attributes.Add("style", "vnd.ms-excel.numberformat: @;");
dg.Cells[6].Attributes.Add("style", "vnd.ms-excel.numberformat: @;");
dg.Cells[8].Attributes.Add("style", "vnd.ms-excel.numberformat: @;");
}
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment;filename=" + System.Web.HttpUtility.UrlEncode("学生表" + filename, System.Text.Encoding.UTF8) + ".xls");//导出文件命名
Response.ContentEncoding = System.Text.Encoding.UTF7;//如果设置为"GB2312"则中文字符可能会乱码
Response.ContentType = "applicationshlnd.xls";
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
Panel1.RenderControl(oHtmlTextWriter);//Add the Panel into the output Stream.
Response.Write(oStringWriter.ToString());//Output the stream.
Response.Flush();
Response.End();
}
//重载VerifyRenderingInServerForm方法，否则运行的时候会出现如下错误提示：“类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内”
public override void VerifyRenderingInServerForm(Control control)
{
//override VerifyRenderingInServerForm.
}
