将选中的Gridview行导出为pdf [英] Export checked Gridview rows to pdf

问题描述

我有用于将已检查的gridview行导出到excel的代码，但无法修改代码以便以相同的方式导出pdf文件。

protected void btnExportExcel_Click(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";
            StringWriter sw = new StringWriter();
            HtmlTextWriter hw = new HtmlTextWriter(sw);

            GridView1.AllowPaging = false;
            GridView1.DataBind();

            GridView1.HeaderRow.Style.Add("background-color", "#FFFFFF");
            GridView1.HeaderRow.Cells[0].Visible = false;
            GridView1.HeaderRow.Cells[4].Visible = false;
            GridView1.HeaderRow.Cells[1].Style.Add("background-color", "#285D8B");
            GridView1.HeaderRow.Cells[2].Style.Add("background-color", "#285D8B");
            GridView1.HeaderRow.Cells[3].Style.Add("background-color", "#285D8B");

            if (ViewState["CheckBoxArray"] != null)
            {
                ArrayList CheckBoxArray = (ArrayList)ViewState["CheckBoxArray"];
                string checkAllIndex = "chkAll-" + GridView1.PageIndex;
                int rowIdx = 0;
                for (int i = 0; i < GridView1.Rows.Count; i++)
                {
                    GridViewRow row = GridView1.Rows[i];
                    row.Visible = false;

                    if (row.RowType == DataControlRowType.DataRow)
                    {
                        if (CheckBoxArray.IndexOf(i + 1) != -1)
                        {
                            row.Visible = true;
                            row.BackColor = System.Drawing.Color.White;
                            row.Cells[0].Visible = false;
                            row.Cells[4].Visible = false;
                            row.Attributes.Add("class", "textmode");
                            if (rowIdx % 2 != 0)
                            {
                                row.Cells[1].Style.Add("background-color", "#cedae4");
                                row.Cells[2].Style.Add("background-color", "#cedae4");
                                row.Cells[3].Style.Add("background-color", "#cedae4");
                                row.Cells[5].Style.Add("background-color", "#cedae4");
                            }
                            rowIdx++;
                        }
                    }
                }
            }
            GridView1.RenderControl(hw);
            string style = @"<style> .textmode { mso-number-format:\@; } </style>";
            Response.Write(style);
            Response.Output.Write(sw.ToString());
            Response.End();
        }
