c# - 使用 FastReport.Net 创建报告

Question

我已经安装了FastReport.Net用于生成报告。

我包含了以下引用资料:

FastReport.dll , FastReport.Web.dll , FastReport.Bars.dll , FastReport.Editor.dll , FastReport.Service.dll

我还在工具箱中创建了一个名为 FastReport.Net 的自定义选项卡，并将 FastReport 控件/组件添加到该选项卡，我拥有的控件是:

Pointer and WebReport

我已将 WebReport 组件拖放到我的 .aspx 页面上，这使我的 web.config 如下所示:

<?xml version="1.0"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0">
      <assemblies>
        <add assembly="FastReport.Web, Version=2016.3.13.0, Culture=neutral, PublicKeyToken=DB7E5CE63278458C" />
        <add assembly="System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />
        <add assembly="FastReport, Version=2016.3.13.0, Culture=neutral, PublicKeyToken=DB7E5CE63278458C" />
      </assemblies>
    </compilation>
  </system.web>
  <connectionStrings>
    <add name="ConnectionString" connectionString="Data Source=WIN-SERVER;Initial Catalog=RndDatabase;User ID=development;Password=development" providerName="System.Data.SqlClient" />
  </connectionStrings>
  <system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <handlers>
      <add name="FastReportHandler" path="FastReport.Export.axd" verb="*" type="FastReport.Web.Handlers.WebExport" />
    </handlers>
  </system.webServer>
</configuration>

我的问题是如何从数据库中获取数据并使用 FastReport 打印报告。

我在我的项目中创建了一个 dataset.xsd，但是当我从 FastReport 上的设计中单击 Select DataSource... 时(ctrl+Shift +F10) 它会打开一个没有可供选择的选项的弹出窗口。

还有其他的程序吗？

            Report report = new Report();
            // register the "Cities" table
            report.RegisterData(_dataSet.Tables[0], "Cities");

            report.GetDataSource("Cities").Enabled = true;
            // create A4 page with all margins set to 1cm
            ReportPage page1 = new ReportPage();
            page1.Name = "Page1";
            report.Pages.Add(page1);

            // set its height to 1.5cm
            page1.ReportTitle.Height = Units.Centimeters * 1.5f;
            // create group header
            GroupHeaderBand group1 = new GroupHeaderBand();
            group1.Name = "Cities Data";
            group1.Height = Units.Centimeters * 1;
            // set group condition
            group1.Condition = "[Cities.CityName]";//[Cities.CityName].Substring(0, 1)
            // add group to the page.Bands collection
            page1.Bands.Add(group1);
            // create group footer
            group1.GroupFooter = new GroupFooterBand();
            group1.GroupFooter.Name = "GroupFooter1";
            group1.GroupFooter.Height = Units.Centimeters * 1;
            // create DataBand
            DataBand data1 = new DataBand();
            data1.Name = "Data1";
            data1.Height = Units.Centimeters * 0.5f;
            // set data source
            data1.DataSource = report.GetDataSource("Cities");
            // connect databand to a group
            group1.Data = data1;
            // create "Text" objects
            // report title
            TextObject text1 = new TextObject();
            text1.Name = "Text1";
            // set bounds
            text1.Bounds = new System.Drawing.RectangleF(0, 0,
            Units.Centimeters * 19, Units.Centimeters * 1);
            // set text
            text1.Text = "CitiesData";
            // set appearance
            text1.HorzAlign = HorzAlign.Center;
            text1.Font = new System.Drawing.Font("Tahoma", 14, FontStyle.Bold);
            // add it to ReportTitle
            page1.ReportTitle.Objects.Add(text1);
            // group
            TextObject text2 = new TextObject();
            text2.Name = "Text2";
            text2.Bounds = new RectangleF(0, 0,
            Units.Centimeters * 2, Units.Centimeters * 1);
            text2.Text = "[Cities.CityName]";//[Cities.CityName].Substring(0, 1)
            text2.Font = new Font("Tahoma", 10, FontStyle.Bold);
            // add it to GroupHeader
            group1.Objects.Add(text2);
            report.Show();
        }
    }
}

这里我想在点击一个按钮时生成一个报告，当点击一个按钮生成报告时，它在 report.Show(); 行给我一个错误说:

DragDrop registration did not succeed.

当我继续执行时，它会在 report.Show(); 处停止执行。

一种方法是您可以使用名为 WebReport 的 FastReport 控件。

为此，您需要做的就是在工具箱中创建一个新的自定义选项卡，步骤如下:

• 右键单击工具箱并单击创建名为 FastReport 的新选项卡(您可以提供任何名称)
• 添加FastReport的dll
• 在此之后拖放 Webreport 控件并创建报告。
• 如果您想通过菜单添加 DataSource 与数据库交互。

就是这样!
