GridView中的数据导出到Excel方法(经测试完整)

GridView中的数据导出到Excel方法(经测试完整)

protected void Button2_Click(object sender, EventArgs e)
{
if (this.GridView1.Rows.Count == 0)
{
Response.Write("<script>alert('没有查找到数据,无法导出！')");
}
else
{
this.GridView1.AllowPaging = false; // 将有分页的GridView中的数据全部导出到Excel
gvBond();
export("application/ms-excel", "工作人员.xls");
// 换成 export("application/ms-word", "工作人员.doc"); 那么导出的就是Word格式的了.
this.GridView1.AllowPaging = true;
gvBond();
}
}
public void export(string FileType, string FileName)
{
string style = @"<style>.text{mso-number-format:/@}</script>";//导入到excel时,保存表里数字列中前面存在的 0 .
Response.Clear();
Response.Charset = "GB2312";
Response.ContentEncoding = Encoding.UTF7;
Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
Response.ContentType = FileType;
this.EnableViewState = false;
this.GridView1.AllowPaging = false;
System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN", true);
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
this.GridView1.RenderControl(htw);
Response.Write(style);
Response.Write(sw.ToString());
//Response.Write(dt.ToString());
Response.End();
}

public override void VerifyRenderingInServerForm(Control control)
{
//在后台中重载VerifyRenderingInServerForm()方法，否则报错为“类型"GridView"的控件"GridView1"必须放在具有 runat=server 的窗体标记内“
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[3].Attributes.Add("class", "text");//在数字列前存在的 0 的列中加入 class 样式 以便保存 0
}
}

注:如果GricView中有分页的话,导出到Excel时就会报错.可通过修改页文件可以修正这个问题：EnableEventValidation = "false".
