Question

我有一个gridview，它在运行时添加了多个标题，如下面的snap中所示：

我想将此gridview中的数据导出到excel，我有以下代码：

protected void Button1_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";
        using (StringWriter sw = new StringWriter())
        {
            HtmlTextWriter hw = new HtmlTextWriter(sw);
            gdView.HeaderRow.BackColor = Color.White;
            foreach (TableCell hcell in gdView.HeaderRow.Cells)
            {
                hcell.BackColor = Color.White;
            }
            foreach (GridViewRow row in gdView.Rows)
            {
                {
                    row.BackColor = Color.White;
                    foreach (TableCell cell in row.Cells)
                    {
                        cell.CssClass = "textmode";
                    }
                }
            }
            gdView.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(System.Web.UI.Control control)
    {
        // controller   
    }

我得到的excel输出如下：

正如您所看到的，标题行的颜色继续超出表格区域。此外，顶部标题行在Excel输出中折叠。

请大家好好建议如何解决这个问题。

感谢。

我最终可以通过修改代码解决问题：

protected void Button1_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";
        using (StringWriter sw = new StringWriter())
        {
            HtmlTextWriter hw = new HtmlTextWriter(sw);
            for (int x = 0; x <= 3; x++)
            {
                GridViewRow rows = (GridViewRow)gdView.HeaderRow.Parent.Controls[x];
                rows.BackColor = Color.White;
                rows.Height = 15;
                for (int i = 0; i <= rows.Cells.Count - 1; i++)
                {
                    rows.Cells[i].BackColor = Color.Maroon;
                }
            } 
            foreach (GridViewRow row in gdView.Rows)
            {
                row.BackColor = Color.White;
                foreach (TableCell cell in row.Cells)
                {
                    cell.VerticalAlign = VerticalAlign.Middle;
                    cell.CssClass = "textmode";
                }
            }
            gdView.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(System.Web.UI.Control control)
    {
        // controller   
    }
