RDLC报表实现二维码打印功能
虽然RDLC中的矩阵可以扩展列，但是无法满足我需要完成的功能。所以在一个报表中放置了多个矩阵，每个矩阵绑定一个数据集，再通过XML数据控制显示的行数列数及分配给的数据集。
代码：
分页：工具箱中拖一个列表过来，设置 列表-->行组-->组属性
常规-->组表达式=Int((RowNumber(Nothing)-1)/10)
分页符-->勾选在组的结尾。工具箱中拖一个矩阵，放在列表中，然后可以对表进行随意设计，表中分组就会自动按照10条一页进行分页。
控制每个Matrix是否可见（实质控制每个Rectangle可见，可在Matrix中列表的空白区域右击有可见的选项，对应有XML的变化）
private void LetSecondRecVisible() //删除Visibility节点
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(AppDomain.CurrentDomain.BaseDirectory + "MaterielManagement/MaterielOper/MaterielReport.rdlc");
XmlNode recNodeList = xmlDoc.GetElementsByTagName("Rectangle").Item(1);
XmlNodeList test = xmlDoc.GetElementsByTagName("Visibility");
if (null != recNodeList && test.Count!=0)
{
XmlNode recVisibleNode = recNodeList.ChildNodes[2];
recNodeList.RemoveChild(recVisibleNode);
xmlDoc.Save(AppDomain.CurrentDomain.BaseDirectory + "MaterielManagement/MaterielOper/MaterielReport.rdlc");
}
}
private void LetSecondRecHidden() //插入Visibility节点，将Hidden节点置为true
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(AppDomain.CurrentDomain.BaseDirectory + "MaterielManagement/MaterielOper/MaterielReport.rdlc");
if (xmlDoc.GetElementsByTagName("Visibility") == null || xmlDoc.GetElementsByTagName("Visibility").Count==0)
{
XmlElement xmlElement = xmlDoc.CreateElement("Visibility",xmlDoc.DocumentElement.NamespaceURI);
XmlNode xmlNode = xmlDoc.GetElementsByTagName("Rectangle").Item(1);/Rectangle节点
XmlNode keepTogtherNode = xmlNode.ChildNodes[1];
XmlNode xmlVisibleNode = xmlNode.AppendChild(xmlElement); /返回的插入的节点
XmlElement xmlHiddenElement = xmlDoc.CreateElement("Hidden", xmlDoc.DocumentElement.NamespaceURI);
xmlHiddenElement.InnerText = "true";
xmlVisibleNode.PrependChild(xmlHiddenElement);
xmlDoc.Save(AppDomain.CurrentDomain.BaseDirectory + "MaterielManagement/MaterielOper/MaterielReport.rdlc"); //插入Visibility节点 true
}
}控制每页显示行数：
private void SetPageItems(string num) /设置每页显示二维码的个数
{
try
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(AppDomain.CurrentDomain.BaseDirectory + "MaterielManagement/MaterielOper/MaterielReport.rdlc");
if ("one" == num || "two" == num)
{
XmlNodeList groupNodeList = xmlDoc.GetElementsByTagName("TablixRowHierarchy");
foreach (XmlNode groupNode in groupNodeList)
{
XmlNode grouping= groupNode.FirstChild.FirstChild.FirstChild;
foreach (XmlAttribute xmlAttribute in grouping.Attributes)
{
if (xmlAttribute.Value != null && ("详细信息" == xmlAttribute.Value || xmlAttribute.Value == "详细信息1")) 每页显示一行
{
grouping.FirstChild.FirstChild.InnerText = "=Int((RowNumber(Nothing)-1)/1)";
}
}
}
}
if ("four" == num)
{
XmlNodeList groupNodeList = xmlDoc.GetElementsByTagName("TablixRowHierarchy");
foreach (XmlNode groupNode in groupNodeList)
{
XmlNode grouping = groupNode.FirstChild.FirstChild.FirstChild;
foreach (XmlAttribute xmlAttribute in grouping.Attributes)
{
if (xmlAttribute.Value != null && ("详细信息" == xmlAttribute.Value || xmlAttribute.Value == "详细信息1")) 每页显示两行
{
grouping.FirstChild.FirstChild.InnerText = "=Int((RowNumber(Nothing)-1)/2)";
}
}
}
}
if ("six" == num)
{
XmlNodeList groupNodeList = xmlDoc.GetElementsByTagName("TablixRowHierarchy");
foreach (XmlNode groupNode in groupNodeList)
{
XmlNode grouping = groupNode.FirstChild.FirstChild.FirstChild;
foreach (XmlAttribute xmlAttribute in grouping.Attributes)
{
if (xmlAttribute.Value!= null&&("详细信息" == xmlAttribute.Value || xmlAttribute.Value == "详细信息1")) 每页显示三行
{
grouping.FirstChild.FirstChild.InnerText = "=Int((RowNumber(Nothing)-1)/3)";
}
}
}
}
xmlDoc.Save(AppDomain.CurrentDomain.BaseDirectory + "MaterielManagement\\MaterielOper\\MaterielReport.rdlc");
xmlDoc.Load(AppDomain.CurrentDomain.BaseDirectory + "MaterielManagement\\MaterielOper\\MaterielReport.rdlc");
}
catch (Exception ex)
{
}
}加载两列数据，对两个数据集进行赋值：
private void PrintTwoColumnsBarCodeXml() /显示两列数据
{
dt = GetDataSource();
string filePath = ConfigurationManager.AppSettings["FileDirName"];
//站点文件存储路径
string sysFilePath = Global.ServerFilePath.Replace("\\", "/");
//文件类型
string uploadPath = sysFilePath + "/BarCode/";
DataTable anthorSource = new DataTable();
DataTable firstSource = new DataTable();
firstSource = dt.Clone();
anthorSource = dt.Clone();
for (int i = 0; i < dt.Rows.Count; i++)
{
if (0 != i % 2)i为奇数，matrix为第二列
{
DataRow cRow = dt.Rows[i];
anthorSource.ImportRow(cRow);
string imagePath = Path.Combine(uploadPath, cRow["BarCode_Position"] == DBNull.Value ? "blank.png" : cRow["BarCode_Position"].ToString());
ReportParameter MatrixColumnSecond = new ReportParameter("MatrixColumnSecond", "file:///" + imagePath);
MaterielReportViewer.LocalReport.SetParameters(new ReportParameter[] {MatrixColumnSecond});
}
else
{
DataRow cRow = dt.Rows[i];
firstSource.ImportRow(cRow);
string imagePath = Path.Combine(uploadPath, cRow["BarCode_Position"] == DBNull.Value ? "blank.png" : cRow["BarCode_Position"].ToString());
ReportParameter MatrixColumnFirst = new ReportParameter("MatrixColumnFirst", "file:///" + imagePath);
MaterielReportViewer.LocalReport.SetParameters(new ReportParameter[] { MatrixColumnFirst });
}
}
ReportDataSource dataReport = new ReportDataSource("materielInfo", firstSource);
ReportDataSource dataSecondReport = new ReportDataSource("ImageSecond", anthorSource);
MaterielReportViewer.LocalReport.DataSources.Add(dataReport);
MaterielReportViewer.LocalReport.DataSources.Add(dataSecondReport);
MaterielReportViewer.LocalReport.Refresh();
}在Matrix中添加图片每行显示不同的图片，本人实验不能通过参数来引用外部图片，这样每行显示的图片都是同一个，必须通过将图片直接存入数据库中。如果有人成功，希望给出解决办法！！！
