单击导出按钮时我想导出 aspx gridview？

Question

我想在单击导出按钮时导出 ASPxGridView。

我正在使用下面的代码，但没有得到所需的结果：

protected void btn_excel_Click1(object sender, EventArgs e)
    {
        ASPxGridViewExporter1 . WriteXlsToResponse();
    }

Answer 1

如果要将网格视图数据导出到 excel，则使用数据 table。将 gridview 数据绑定到数据 table 并将数据 table 数据导出到 excel。

Answer 2

导出到 Excel 使用此代码。

<asp:GridView ID="GrdAccess" runat="server" AutoGenerateColumns="false" Width="70%" AllowPaging="true" PageSize="20" CssClass="Grid" RowStyle-BackColor="#A1DCF2" AlternatingRowStyle-BackColor="White" AlternatingRowStyle-ForeColor="#000" PagerStyle-CssClass="pgr" OnPageIndexChanging="GrdAccess_PageIndexChanging"></asp:GridView>

protected void ExportToExcel(object sender, EventArgs e)
        {
            Response.Clear();
            Response.Buffer = true;
            Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.xls");
            Response.Charset = "";
            Response.ContentType = "application/vnd.ms-excel";
            using (StringWriter sw = new StringWriter())
            {
                HtmlTextWriter hw = new HtmlTextWriter(sw);

                //To Export all pages
                GrdAccess.AllowPaging = false;
                this.getProjectDetails();

                GrdAccess.HeaderRow.BackColor = Color.White;
                foreach (TableCell cell in GrdAccess.HeaderRow.Cells)
                {
                    cell.BackColor = GrdAccess.HeaderStyle.BackColor;
                }
                foreach (GridViewRow row in GrdAccess.Rows)
                {
                    row.BackColor = Color.White;
                    foreach (TableCell cell in row.Cells)
                    {
                        if (row.RowIndex % 2 == 0)
                        {
                            cell.BackColor = GrdAccess.AlternatingRowStyle.BackColor;
                        }
                        else
                        {
                            cell.BackColor = GrdAccess.RowStyle.BackColor;
                        }
                        cell.CssClass = "textmode";
                    }
                }

                GrdAccess.RenderControl(hw);

                //style to format numbers to string
                string style = @"<style> .textmode { } </style>";
                Response.Write(style);
                Response.Output.Write(sw.ToString());
                Response.Flush();
                Response.End();
            }
        }


    public override void VerifyRenderingInServerForm(Control control)
        {

        }

试试这个

Session["Excel"] - 您要导出的项目（在我的例子中，我将其存储在会话中）。

使用 (var exporter = new NpoiExport()) {

    DataTable dt = new DataTable();
    dt = (DataTable)Session["Excel"];
    exporter.ExportDataTableToWorkbook(dt, "Result");

    string saveAsFileName = string.Format("Results-{0:d}.xls", DateTime.Now);


    Response.ContentType = "application/excel";

    Response.AddHeader("Content-Disposition", string.Format("attachment;filename={0}", saveAsFileName));

    Response.Clear();

    Response.BinaryWrite(exporter.GetBytes());

    Response.End();
}
