C＃Devexpress，更新报告

Question

使用C sharp，winforms，visual studio 2010，.NET 4和devexpress API。

嗨，我最近试图使用devexpress xtreport控件进行报告。 它工作正常，看起来不错，唯一的问题是我需要它在运行时更新。

我遇到的问题是当我的控件更新时，我需要它们将值传递给我的报告，到目前为止，这不工作，也不是我的报告xtrachart，没有更新。

如果有这样的方法，我正在徘徊我应该调用更新整个报告。

原因我正在使用文本框值放入报表是由于报表的显示不会改变，事实上我正在使用少量的数据在我的Winforms应用程序中得到处理。

继承人一些代码：

public partial class XtraReport1 : DevExpress.XtraReports.UI.XtraReport

    DataTable chartTable3 = new DataTable("Table1"); 
    DataTable chartTable4 = new DataTable("Table2");

      xrChart1.Series.Add(series6); 

      xrChart1.Legend.Visible = true; 


    } 
} 

我意识到这个代码需要大量的清理工作，因为它可以做了很多整洁短，但这是暂时的测试，如果我能得到的报告工作。 也请原谅方法和变量与坏名字，这些被映射到我的设计作为我的参考，并且当这完成时也将被改变，我可以想出一些好名字。

非常感谢。我的报告

代码更新报告：

//XtraReport1 is your report 
XtraReport1 report = new XtraReport1(); 
//Open print preview form 
report.ShowPreview(); 

//Update your report content 
report.myChartSeries2(1,2,3,4,DateTime.Now.ToShortTimeString()); 
//Recreate/update document in print preview 
report.CreateDocument();
