数据填充方式XML/JSON预览。

一：xml填充：更加方便右击主对象增加明细网格

增加列组合

右击记录集增加字段集合

选中内容行列设置数据字段

例子测试：

using gregn6Lib;
namespace StudentTest
{
    public partial class Form1 : Form
    {
        private GridppReport report = new GridppReport();
        public Form1()
        {
            InitializeComponent();
        }
        private void button1_Click(object sender, EventArgs e)
        {
            report.Clear();
            report.PrepareLoadData();
            report.LoadFromFile(@"MyStudent.grf");
            report.LoadDataFromXML(GetAllBodyXML());
            report.PrintPreview(true);
        }
        private string GetAllBodyXML()
        {
            XmlDocument bodyDoc = new XmlDocument();
            XmlElement element = bodyDoc.CreateElement("BarCode");
            bodyDoc.AppendChild(element);
            XmlNode rootNode = bodyDoc.SelectSingleNode("BarCode");
            XmlElement xe = null;
            DataTable dtUnique = new DataTable();
            dtUnique.Columns.Add(new DataColumn("StudentAge"));
            dtUnique.Columns.Add(new DataColumn("StudentName"));
            dtUnique.Columns.Add(new DataColumn("StudentClass"));
            DataRow dr = dtUnique.NewRow();
            dr["StudentAge"] = "18";
            dr["StudentName"] = "小明";
            dr["StudentClass"] = "三年二班";
            dtUnique.Rows.Add(dr);
            DataRow dr2 = dtUnique.NewRow();
            dr2["StudentAge"] = "28";
            dr2["StudentName"] = "小明";
            dr2["StudentClass"] = "三年二班";
            dtUnique.Rows.Add(dr2);
            //方式一自己拼接
            //foreach (DataRow dr2 in dtUnique.Rows)
            //{
            //        xe = bodyDoc.CreateElement("Details");
            //        xe.SetAttribute("StudentAge", Convert.ToString(dr["StudentAge"]));
            //        xe.SetAttribute("StudentName", Convert.ToString(dr["StudentName"]));
            //        xe.SetAttribute("StudentClass", Convert.ToString(dr["StudentClass"]));
            //        rootNode.AppendChild(xe);
            //}
            //return bodyDoc.OuterXml;
            //方式二利用dataset更加方便
            DataSet ds = new DataSet();
            ds.Tables.Add(dtUnique);
            return  ds.GetXml();
        }  
    }
}

二：测试二

右击增加明细网格，增加自由表格，增加记录集，条形码中点击文本插入字段

        private void button1_Click(object sender, EventArgs e)
        {
            report.Clear();
            report.PrepareLoadData();
            report.LoadFromFile(@"Test.grf");
            report.LoadDataFromXML(GetAllBodyXML());
            report.PrintPreview(true);
        }
        private string GetAllBodyXML()
        {
           //测试二
            DataTable dtUnique = new DataTable();
            dtUnique.Columns.Add(new DataColumn("cInvCode"));
            dtUnique.Columns.Add(new DataColumn("cInvName"));
            dtUnique.Columns.Add(new DataColumn("cInvStd"));
            dtUnique.Columns.Add(new DataColumn("cBarCode"));
            DataRow dr = dtUnique.NewRow();
            dr["cInvCode"] = "147258369";
            dr["cInvName"] = "德芙巧克力";
            dr["cInvStd"] = "30mm*20mm";
            dr["cBarCode"] = "6943620580207";
            dtUnique.Rows.Add(dr);
            DataRow dr2 = dtUnique.NewRow();
            dr2["cInvCode"] = "123456789";
            dr2["cInvName"] = "杯子";
            dr2["cInvStd"] = "500mm*200mm";
            dr2["cBarCode"] = "6943620580207";
            dtUnique.Rows.Add(dr2);
            DataSet ds = new DataSet();
            ds.Tables.Add(dtUnique);
            return ds.GetXml();
        }  
    }

测试二

<Data>
	<Rows>
		<Row>
		 <cInvCode>02001</cInvCode>
		 <cInvName>存货A</cInvName>
		 <cBarCode>200,2jjj,698</cBarCode>
		 <cVenName>供应商A</cVenName>
		 <cInvStd>2018*20mm</cInvStd>
		 <PackSize>200</PackSize>
		 <iQuantity>30</iQuantity>
		 <cBatch>20180913</cBatch>
		</Row>
		<Row>
		 <cInvCode>02002</cInvCode>
		 <cInvName>存货B</cInvName>
		 <cBarCode>200,2jjj,AA</cBarCode>
		 <cVenName>供应商A</cVenName>
		 <cInvStd>2018*20mm</cInvStd>
		 <PackSize>200</PackSize>
		 <iQuantity>50</iQuantity>
		 <cBatch>20180913</cBatch>
		</Row>
	</Rows>
</Data>

上面的数据保存为xml文件，设置数据源xml即可测试预览

实际应用场景：数据库返回DataTable，转DataSet=>xml填充
