1.修改页边距

XmlDocument XMLDoc = new XmlDocument();

XMLDoc.Load(System.Windows.Forms.Application.StartupPath + @"Report_try-2.rdlc");

XmlNamespaceManager xmn = new XmlNamespaceManager(XMLDoc.NameTable);

xmn.AddNamespace("X", "http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition");

string strXPath;

strXPath = "/X:Report/X:Page/X:LeftMargin"; 

XmlNode Node = XMLDoc.SelectSingleNode(strXPath, xmn).ChildNodes.Item(0);     // 读取左边距

Node.InnerText = "20mm";      // 左边距改为20mm

XMLDoc.Save(System.Windows.Forms.Application.StartupPath + @"Report_try-2.rdlc");  // 写XML

 

修改右、上、下边距方法和上述方法一样,只需要更改 strXPath = "/X:Report/X:Page/X:LeftMargin"; 

 

2.修改表格列宽

XmlDocument XMLDoc = new XmlDocument();

XMLDoc.Load(System.Windows.Forms.Application.StartupPath + @"Report_try-2.rdlc");

XmlNamespaceManager xmn = new XmlNamespaceManager(XMLDoc.NameTable);

xmn.AddNamespace("X", "http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition");

string strXPath;

strXPath = "/X:Report/X:Body/X:ReportItems/X:Tablix/X:TablixBody";

XmlNodeList NDList = XMLDoc.SelectSingleNode(strXPath, xmn).ChildNodes;

XmlNode subNode = NDList.Item(0);

/*

subNode.ChildNodes.Count即为报表列数

subNode.ChildNodes.Item(X).innerText即为第X列的列宽,X下标从0开始

*/

subNode.ChildNodes.Item(0).InnerText = "20mm";     // 修改第一列列宽为20mm

XMLDoc.Save(System.Windows.Forms.Application.StartupPath + @"Report_try-2.rdlc");  // 写XML
