数据导出问题
导出数据到excel中的代码
[code=C#][/code]
Response.Clear();
Response.Buffer = true;
//编码控制
//Response.Charset = "utf-8 ";
//Response.ContentEncoding = System.Text.Encoding.GetEncoding( "utf-8 ");
Response.Charset = "GB2312 ";
Response.ContentEncoding = System.Text.Encoding.GetEncoding( "GB2312 ");
Response.AppendHeader( "Content-Disposition ", "attachment;filename=UserInfo.xls ");
Response.ContentType = "application/ms-excel ";
this.EnableViewState = false;
System.IO.StringWriter swOut = new System.IO.StringWriter();
HtmlTextWriter hTw = new HtmlTextWriter(swOut);
myGW.RenderControl(hTw);
Response.Write(swOut.ToString());
Response.End();
//上面是Button事件代码
//myGw是是一个gridview控件,有几个字段,其中有一个身份证号码字段,通过导出到excel后身份证号码不能正常显示,他显示的是5.13701E+17,展开后后三位是0,怎样才能使它正常显示呢?
[解决办法]
Asp.Net WebForm中DataGrid导出的时候,在ItemDataBound内 就OK 了
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
e.Item.Cells[0].Attributes.Add("style","vnd.ms-excel.numberformat:@");
}
[解决办法]
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) { e.Row.Cells[4].Attributes.Add("style","vnd.ms-excel.numberformat:@"); }
