推荐答案

点击要从gridview生成excel表格的按钮，使用gridview作为参数调用此函数，例如

Onclick of the button on which you want to generate excel sheet from gridview,call this function with gridview as parameter,e.g.

GenerateExcel(Your gridview here)

然后，实现以下两个函数。

Then,implement below two functions.

public static void GenerateExcel(GridView gv)
        {
            HttpContext.Current.Response.Clear();
            HttpContext.Current.Response.AppendHeader("Content-disposition", "attachment; filename=Leave_Report.xls");
            HttpContext.Current.Response.ContentType = "application/ms-excel";

            using (StringWriter sw = new StringWriter())
            {
                using (HtmlTextWriter htw = new HtmlTextWriter(sw))
                {
                    //  Create a table to contain the grid
                    Table table = new Table();

                    //  include the gridline settings
                    table.GridLines = gv.GridLines;

                    //  add the header row to the table
                    if (gv.HeaderRow != null)
                    {
                        PrepareControlForExport(gv.HeaderRow);
                        table.Rows.Add(gv.HeaderRow);
                    }
                    //Make Header Coloruful

                    for (int j = 0; j < gv.Columns.Count; j++)
                    {
                        //Apply style to Individual Cells
                        gv.HeaderRow.Cells[j].Style.Add("background-color", "#4DB4EE");

                    }

                    //  add each of the data rows to the table
                    foreach (GridViewRow row in gv.Rows)
                    {
                        PrepareControlForExport(row);
                        table.Rows.Add(row);
                    }

                    //  add the footer row to the table
                    if (gv.FooterRow != null)
                    {
                        PrepareControlForExport(gv.FooterRow);
                        table.Rows.Add(gv.FooterRow);
                    }

                    //  render the table into the htmlwriter
                    table.RenderControl(htw);

                    //  render the htmlwriter into the response
                    HttpContext.Current.Response.Write(sw.ToString());
                    HttpContext.Current.Response.End();
                }
            }


        }
        private static void PrepareControlForExport(Control control)
        {
            for (int i = 0; i < control.Controls.Count; i++)
            {
                Control current = control.Controls[i];
                if (current is LinkButton)
                {
                    control.Controls.Remove(current);
                    control.Controls.AddAt(i, new LiteralControl((current as LinkButton).Text));
                }
                else if (current is ImageButton)
                {
                    control.Controls.Remove(current);
                    control.Controls.AddAt(i, new LiteralControl((current as ImageButton).AlternateText));
                }
                else if (current is HyperLink)
                {
                    control.Controls.Remove(current);
                    control.Controls.AddAt(i, new LiteralControl((current as HyperLink).Text));
                }
                else if (current is DropDownList)
                {
                    control.Controls.Remove(current);
                    control.Controls.AddAt(i, new LiteralControl((current as DropDownList).SelectedItem.Text));
                }
                else if (current is CheckBox)
                {
                    control.Controls.Remove(current);
                    control.Controls.AddAt(i, new LiteralControl((current as CheckBox).Checked ? "True" : "False"));
                }

                if (current.HasControls())
                {
                    PrepareControlForExport(current);
                }
            }
        }
