问题描述

我使用printwebhelper方法打印gridview内容



i只需将gridview传递给班级



该课程为：

I am using printwebhelper method for printing the gridview content

i just pass gridview to the class

the class is :

public static void PrintWebControl(Control ctrl, string Script, GridView SalesGridView)
    {
        //if (System.Web.HttpContext.Current.(string)Session["isgrid"] == "grid")
        //{
        //    GridView grid = (GridView)ctrl;
        //    grid.AllowPaging = false;
        //    grid.DataBind();
        if (SalesGridView.Rows.Count > 0)
        {
            //}

            SalesGridView.UseAccessibleHeader = true;
            SalesGridView.HeaderRow.TableSection = TableRowSection.TableHeader;
            SalesGridView.FooterRow.TableSection = TableRowSection.TableFooter;
            SalesGridView.Attributes["style"] = "border-collapse:separate";
            foreach (GridViewRow row in SalesGridView.Rows)
            {
                if (row.RowIndex % 30 == 0 && row.RowIndex != 0)
                {
                    row.Attributes["style"] = "page-break-after:always;";
                }
            }

            StringWriter stringWrite = new StringWriter();
            System.Web.UI.HtmlTextWriter htmlWrite = new System.Web.UI.HtmlTextWriter(stringWrite);
            if (ctrl is WebControl)
            {
                Unit w = new Unit(100, UnitType.Percentage); ((WebControl)ctrl).Width = w;
            }
            Page pg = new Page();
            pg.EnableEventValidation = false;
            if (Script != string.Empty)
            {
                pg.ClientScript.RegisterStartupScript(pg.GetType(), "PrintJavaScript", Script);
            }
            HtmlForm frm = new HtmlForm();
            pg.Controls.Add(frm);
            frm.Attributes.Add("runat", "server");
            frm.Controls.Add(ctrl);
            pg.DesignerInitialize();
            pg.RenderControl(htmlWrite);
            string strHTML = stringWrite.ToString();
            HttpContext.Current.Response.Clear();
            HttpContext.Current.Response.Write(strHTML);
            HttpContext.Current.Response.Write("<script>window.print();</script>");
            string style = "<style type = 'text/css'>td { padding: 4px; border: solid 1px #c1c1c1; color: #474545; font-family:Arial; font-size:12px } th { padding: 2px 2px; color: #3e4d9e; background: #e0d7f4 ; font-family:Arial; text-align:left;text-indent:10px; font-size:14px ;border-top: solid 1px #a99cec; border-left:none;border-right:none; border-bottom:none }{ width: 100%;background-color: #fff; margin: 5px 0 10px 0; border-top: solid 1px #a99cec; border-left:solid 1px #a99cec;border-right:solid 1px #a99cec;font-family:Arial; font-size:15px; </style>";

            HttpContext.Current.Response.Write(style);
            HttpContext.Current.Response.End();
        }
    }

但是当它到达时

but when it reached

pg.DesignerInitialize();
            pg.RenderControl(htmlWrite);

行显示错误

表必须按标题，正文，然后页脚的顺序包含行部分

line it showing the error
The table must contain row sections in order of header, body, then footer

推荐答案

这是动态创建的页眉还是页脚？



试试这个

Is this a dynamically created header or footer?

Try this

protected void SalesGridView_RowCreated(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowIndex == 0)
    {
        e.Row.RowType = DataControlRowType.Header;

    }
}
