.net下导出sigma_grid数据到Excel

2015-11-05 18:34 447 查看

今天在做sigma_grid导出Excel数据，网上的Demo都是给一个导出Excel的地址，如：

exportURL : './export_php/testList.php?export=true',

但是并没有给出服务端是如何处理的，只好猜想怎么做，传统的Excel导出方法无外乎就那么几种方式，于是对着照写：

将导出Excel路径设置为：

exportURL: '../Ajax/getTableJson.ashx?type=excel',

这样为了导出Excel，采用输出HTML的方式进行导出。

获得数据源DataTable，然后将数据写成HTML，进行输出。实现代码如下：

private void ExporttoExcel(DataTable table,string filename){
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.ContentType = "application/ms-excel";
HttpContext.Current.Response.Write(@"<!DOCTYPE HTML PUBLIC ""-//W3C//DTD HTML 4.0 Transitional//EN"">");
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=" + filename + ".xls");
HttpContext.Current.Response.Charset = "GB2312";
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default;
//sets font
HttpContext.Current.Response.Write("<font style='font-size:10.0pt; font-family:Calibri;'>");
HttpContext.Current.Response.Write("<BR><BR><BR>");
//sets the table border, cell spacing, border color, font of the text, background, foreground, font height
HttpContext.Current.Response.Write("<Table border='1' bgColor='#ffffff' " +
"borderColor='#000000' cellSpacing='0' cellPadding='0' " +
"style='font-size:10.0pt; font-family:Calibri; background:white;'> <TR>");
//am getting my grid's column headers
int columnscount = table.Columns.Count;
for (int j = 0; j < columnscount; j++){      //write in new column
HttpContext.Current.Response.Write("<Td>");
//Get column headers  and make it as bold in excel columns
HttpContext.Current.Response.Write("<B>");
HttpContext.Current.Response.Write(table.Columns[j].ColumnName.ToString());
HttpContext.Current.Response.Write("</B>");
HttpContext.Current.Response.Write("</Td>");
}
HttpContext.Current.Response.Write("</TR>");
foreach (DataRow row in table.Rows)
{//write in new row
HttpContext.Current.Response.Write("<TR>");
for (int i = 0; i < table.Columns.Count; i++){
HttpContext.Current.Response.Write("<Td>");
HttpContext.Current.Response.Write(row[i].ToString());
HttpContext.Current.Response.Write("</Td>");
}

HttpContext.Current.Response.Write("</TR>");
}
HttpContext.Current.Response.Write("</Table>");
HttpContext.Current.Response.Write("</font>");
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
}

效果图为：

虽然问题解决了，但是没明白sigma_grid到底怎么配置才能导出数据，如知道解决可以沟通一下！
