动态RDLC报表（六）
动态RDLC报表类DynamicReport：显示报表和打印
在前面已经人寿了一个空的报表文档，各种节点的数据也已经生成，现在只需把各种节点的数据放进报表文档里，然后加载到ReportViewer中就可以了。
显示报表之前要先传入一个ReportViewer。
private ReportViewer _report;
public void SetReport(ReportViewer reportViewer, DisplayMode displayMode = DisplayMode.PrintLayout, ZoomMode zoomMode = ZoomMode.PageWidth)
{
reportViewer.Dock = System.Windows.Forms.DockStyle.Fill;
reportViewer.SetDisplayMode(displayMode);
reportViewer.ZoomMode = zoomMode;
this._report = reportViewer;
}
生成RDLC报表并显示
public void ShowReport()
{
//将每一个patter转换
if (_reportItemPatterns.Count > 0)
{
var dataSetsString = new StringBuilder();
var tablixString = new StringBuilder();
foreach (var reportItemPattern in _reportHeadPatterns)
{
dataSetsString.Append(reportItemPattern.DataSetString);
tablixString.Append(reportItemPattern.TablixString);
}
foreach (var reportItemPattern in _reportItemPatterns)
{
dataSetsString.Append(reportItemPattern.DataSetString);
tablixString.Append(reportItemPattern.TablixString);
}
foreach (var reportRemarksPattern in reportRemarks)
{
tablixString.Append(reportRemarksPattern);
}
//是否显示签名签章
if (isSignature)
{
if (isSignatureImg) tablixString.Append(signaturePattern.Replace("@TopPosition", tabelTopPosition.ToString()).Replace("@LeftPosition", (pageWidth - leftMargin - 9F).ToString()));
}
//把文档中的文字替换掉
if (tablixString.ToString() == "") _docTemplate = _docTemplate.Replace("@Tablix ", "");
_docTemplate = _docTemplate.Replace("@DataSets", dataSetsString.ToString())
.Replace("@Tablix", tablixString.ToString())

if (reportLogoString.ToString() == "")
{
if (reportLabelPatterns.Count > 0)
{
foreach (var reportLabelPattern in reportLabelPatterns)
{
reportLogoString.Append(reportLabelPattern);
}
foreach (var reportTitlePattern in _reportTitlePatterns)
{
reportLogoString.Append(reportTitlePattern);
}

}

}
if (reportPageFooter.ToString() == "")
{

}
else
{
_docTemplate = _docTemplate.Replace("@PageFooter", reportPageFooter.ToString());
}
var doc = new XmlDocument();
doc.LoadXml(_docTemplate);
//doc.Save(System.AppDomain.CurrentDomain.BaseDirectory + "\\docTemplate.xml");
Stream stream = GetRdlcStream(doc);
//加载报表定义
_report.LocalReport.LoadReportDefinition(stream);
_report.LocalReport.DataSources.Clear();
foreach (var reportItemPattern in _reportItemPatterns)
{
_report.LocalReport.DataSources
.Add(new ReportDataSource(reportItemPattern.DataSetName + "Data",
reportItemPattern.Data));
}
foreach (var reportItemPattern in _reportHeadPatterns)
{
_report.LocalReport.DataSources
.Add(new ReportDataSource(reportItemPattern.DataSetName + "Data",
reportItemPattern.Data));
}
_report.LocalReport.Refresh();
if (onlyPrint) PrintStream(_report.LocalReport);
}
}
protected Stream GetRdlcStream(XmlDocument xmlDoc)
{
Stream ms = new MemoryStream();
XmlSerializer serializer = new XmlSerializer(typeof(XmlDocument));
serializer.Serialize(ms, xmlDoc);
ms.Position = 0;
return ms;
}
