教你一个方法
保存DataGrid到Excel实际就是保存你的DataGrid的DataSource(DataTable)到Excel
网上DataSet ,DataTable保存到Excel的例子很多，找不到我帮你找，在原来项目里有

private void Button1_Click(object sender, System.EventArgs e)
{
//this.DataGrid1.AllowPaging = false;
//DB(); 这里需要加你绑定dridgrid的方法
Response.ContentType = "application/vnd.ms-excel ";
System.IO.StringWriter sw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(sw);
DataGrid1.RenderControl(hw);
Response.Write(sw.ToString());
Response.End();
}
