我出于某种原因导致将GridView导出到Excel时出现问题。我有两个按钮,一个是搜索,一旦用户提供了所需的信息,就会处理搜索。另一个按钮是基本上处理gridview出口excel的导出。导出到Excel文件时,GridView导出不会返回任何数据
我的问题是,当用户点击搜索按钮,然后他们想要将数据导出为Excel时,他们需要点击导出按钮。一切都很好,直到这一点,当Excel文件是查看,没有数据导出。这里是我的两个按钮的代码:
任何帮助将不胜感激,谢谢。
protected void search(object sender, EventArgs e)
{
odbc.Open();
ds = new DataSet();
cmd = new OdbcCommand("SELECT XHLBCD AS LOCATION, XHLCST AS STATUS, XHEXUN AS EXCESS, XHSHUN AS SHORT, XHCNTD AS DATE_COUNTED FROM " +
"WM242BASD.XHCTRL00 WHERE XHCNTD BETWEEN '" + fromdate.Text + "' AND '" + todate.Text + "'", odbc);
cmd.CommandType = CommandType.Text;
cmd.Connection = odbc;
oda = new OdbcDataAdapter(cmd);
oda.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();
odbc.Close();
}
protected void export_OnClick(object sender, EventArgs e)
{
// Let's hide all unwanted stuffing
GridView1.AllowPaging = false;
GridView1.AllowSorting = false;
// Let's bind data to GridView
BindGrid();
//Change the color back to white
GridView1.HeaderRow.Style.Add("background-color", "#ffffff");
//Apply color to the header
GridView1.HeaderRow.Cells[0].Style.Add("background-color", "#e0e0e0");
GridView1.HeaderRow.Cells[1].Style.Add("background-color", "#e0e0e0");
GridView1.HeaderRow.Cells[2].Style.Add("background-color", "#e0e0e0");
GridView1.HeaderRow.Cells[3].Style.Add("background-color", "#e0e0e0");
GridView1.HeaderRow.Cells[4].Style.Add("background-color", "#e0e0e0");
// Let's output the GridView
Response.Clear();
Response.ContentType = "application/vnd.xls";
Response.AddHeader("content-disposition", "attachment;filename=" + reportid + ".xls");
StringWriter swriter = new StringWriter();
HtmlTextWriter hwriter = new HtmlTextWriter(swriter);
GridView1.RenderControl(hwriter);
Response.Write(swriter.ToString());
Response.End();
}
private void BindGrid()
{
GridView1.DataBind();
}
谢谢。这工作,是的,我使用这种方式进行测试,只有一次我进入生产我使用SQL参数和StoreProcedures – jorame 2012-02-07 19:50:47
