Question

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

大家好，我最近尝试使用devexpress xtreport控件进行报告。它运行良好，看起来很棒，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他们将值传递给我的报告，到目前为止，这不起作用，也不是我的xtrachart报告，没有任何更新。

如果有这样的方法，我正在徘徊我应该更新整个报告的内容。

原因我正在使用文本框值放入报告中是因为报告的显示从未改变，而且我使用的是在winforms应用程序中处理的少量数据。

下面是一些代码：

public partial class XtraReport1 : DevExpress.XtraReports.UI.XtraReport
{
    DataTable chartTable3 = new DataTable("Table1");
    DataTable chartTable4 = new DataTable("Table2");
    DataTable chartTable5 = new DataTable("Table3");
    DataTable chartTable6 = new DataTable("Table4");
    public DevExpress.XtraReports.UI.XRChart xrChart1;

    public XtraReport1()
    {
        InitializeComponent();

    }

        branch.Text = bname;

        Pg3.Text = pg3k;
        Pg4.Text = pg4k;
    }

    public void TotalSalesk(string totS)
    {
        Sales.Text = totS;
    }

    public void TotalQtyk(string totQ)
    {
        Qty.Text = totQ;
    }

    public void SelectedSales(string pg1S, string pg2S, string pg3S, string pg4S)
    {
        //xrLabel1.Text = label1;

    }

            xrChart1.Series.Add(series6);

            xrChart1.Legend.Visible = true;


    }
}

我意识到这段代码需要大量的清理工作，因为它可以做得更整洁更短，但这是暂时的，可以测试我是否可以让报告工作。还请原谅带有错误名称的方法和变量，这些方法和变量都映射在我的设计上供我参考，并且在完成后也会被更改，我可以想出一些好名字。

非常感谢。

更新报告的代码：

//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();

有关CreateDocument（）方法的更多详情和说明，请访问DevExpress documentation

C＃Devexpress，更新报告
