【Wonder原创】栈板标签列印

一、画面效果如下：

二、打印效果

三、后台代码：

1、全局变量

　　public static int _Cur_index;   //当前页码
　　public static string[] _BoardList; //需要打印的栈板号数组

2、自定义方法

//重置全局变量
        private void ClearVar()
        {
            _Cur_index = 0;
            _BoardList = null;
        }

核心打印方法：

        {
            string CodeNo="", PN="", qty="0", Sdate="",Bindex="";

            foreach (DataRow dr in dt.Rows)
            {
                CodeNo = dr["CodeNo"].ToString();
                PN = dr["PN"].ToString();
                Sdate = dr["DDate"].ToString();
                Bindex = dr["bindex"].ToString();
                qty = (Convert.ToInt32(qty) + Convert.ToInt32(dr["qty"].ToString())).ToString();

3、“查询”按钮事件，查询需要打印的数据

private void btnQuery_Click(object sender, EventArgs e)
        {
            if (drpCUS.SelectedIndex == -1 || drpDept.SelectedIndex == -1)
            {
                MessageBox.Show("请先选择客户及部门.");
                return;
            }
            lblBSum.Text = "0";
            lblQSum.Text = "0";            
            try
            {
                DataSet ds = CDataSet.GetSTList(drpCUS.SelectedItem.ToString(), drpDept.SelectedItem.ToString(), dDate.Value.ToShortDateString(), "%");
                if (ds != null)
                {
                    CDataSet.BindToCombox(drpSTNO, ds.Tables[0], "STNO");
                    if (drpSTNO.Items.Count > 0)
                    {
                        ds = CDataSet.GetSTList(drpCUS.SelectedItem.ToString(), drpDept.SelectedItem.ToString(), dDate.Value.ToShortDateString(), drpSTNO.SelectedItem.ToString());
                        gvData.DataSource = ds.Tables[0];

                        int i = 0;
                        double qty = 0;
                        for (; i < ds.Tables[0].Rows.Count; i++)
                        {
                            qty += Convert.ToDouble(ds.Tables[0].Rows[i]["数量"].ToString());                            
                        }
                        lblBSum.Text = i.ToString();
                        lblQSum.Text = qty.ToString();
                    }
                    else
                    {
                        gvData.DataSource = null;
                        drpSTNO.Text = "";
                        drpSTNO.Items.Clear();
                    }
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

4、“列印全部”按钮事件

private void btnPrint_Click(object sender, EventArgs e)
        {
            try
            {
                StringBuilder sbStr = new StringBuilder();
                ClearVar();
                foreach (DataGridViewRow gr in gvData.Rows)
                {
                    sbStr.Append(gr.Cells[7].Value.ToString());
                    sbStr.Append(",");
                }
                _BoardList = sbStr.ToString().TrimEnd(',').Split(',');
                if (_BoardList != null && _BoardList.Length > 0)
                {
                    printDoc.PrintController = new System.Drawing.Printing.StandardPrintController();//隐藏“正在打印。。。”小窗口
                    printDoc.DefaultPageSettings.Landscape = true;//横向打印
                    printDoc.Print();
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

5、PrintDocument 响应PrintPage事件

打印每一页都会触发这个事件，注意 HasMorePages 达到分页列印效果。

private void printDoc_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            try
            {

                DataSet ds = CDataSet.GetBoard_SEC(_BoardList[_Cur_index].ToString());
                if (ds != null && ds.Tables.Count > 0)
                {
                    //BarcodePrint(e, "LJ01-07716A1", "PL-15-324", "9000", "2010-8-27");
                    BarcodePrint(e, ds.Tables[0]);
                }
                _Cur_index++;
                if (_Cur_index < _BoardList.Length)
                    e.HasMorePages = true;

            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }
