1.如何在WPF应用程序中使用FastReport.Net控件？

您应该为此使用WindowsFormsHost控件：

0）在FastReport.dll上添加引用；

1）如果要使用PreviewControl，则将属性添加到Window（Page）标记中：xmlns：fr =“ clr-namespace：FastReport.Preview; assembly = FastReport”，xmlns：fr1 =“ clr-namespace：FastReport.Design; assembly = FastReport”-if DesignerControl;

2）将WindowsFormsHost标记添加到您的XAML标记中：

 

<WindowsFormsHost HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Grid.Column="0" Grid.ColumnSpan="3">
</WindowsFormsHost>
3）将子级添加到WindowsFormsHost中：<fr：PreviewControl> </ fr：PreviewControl>或<fr1：Designer> </ fr1：Designer>。

 

完整的标记应如下所示：

<Window
 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
 xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
 x:Class="WpfApplication1.MainWindow"
 Title="MainWindow" Height="375.977" Width="939.258"
 xmlns:fr="clr-namespace:FastReport.Preview;assembly=FastReport">
 <Grid>
 <Grid.ColumnDefinitions>
 <ColumnDefinition Width="*"/>
 <ColumnDefinition Width="*"/>
 <ColumnDefinition Width="*"/>
 </Grid.ColumnDefinitions>
 <WindowsFormsHost HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Grid.Column="0" Grid.ColumnSpan="3">
 <fr:PreviewControl></fr:PreviewControl>
 </WindowsFormsHost>
 </Grid>
</Window>

 

2.如何以编程方式设置Format的值？

您可以使用以下代码在脚本或项目中执行此操作：

FastReport.Format.NumberFormat format = new FastReport.Format.NumberFormat();
format.UseLocale = false;
format.DecimalDigits = 2;
format.DecimalSeparator = ".";
format.GroupSeparator = ",";

然后：

textObject.Formats.Clear();
textObject.Formats.Add(format);

3.如何在MSChartObject中创建带有间隙的行？

您应该创建基本的System.Windows.Forms.DataVisualization.Charting.Series对象，并在此处创建行。之后，应为MSChartObject基本图表分配创建的系列（MSChart1.Chart.Series.Add（series）;）不要忘记在“报表”->“脚本”菜单和命名空间System.Windows.Forms中添加 System.Windows.Forms.DataVisualization.dll。 .DataVisualization.Charting。

带有间隙的线的示例：

.
.
using System.Windows.Forms.DataVisualization.Charting;
 
namespace FastReport
{
 public class ReportScript
 {
 private void MSChart1_BeforePrint(object sender, EventArgs e)
 { 
 Series series = new Series("sample");
 series.ChartType = SeriesChartType.Line;
 series.BorderWidth = 2;
 series.MarkerSize = 5;
 
 series.Points.Add(new DataPoint(0, 1));
 series.Points.Add(new DataPoint(1, 2));
 DataPoint dp = new DataPoint(2, double.NaN);
 dp.IsEmpty = true;
 series.Points.Add(dp);
 series.Points.Add(new DataPoint(3, 5));
 series.Points.Add(new DataPoint(4, 8)); 
 
 MSChart1.Chart.Series.Add(series);
 
 }
 }
}

结果：

4.如何从代码创建MSChartObject？

1.创建新的MSChart对象，设置宽度，高度和图例：

 MSChartObject MSChart1 = new MSChartObject();
 MSChart1.Width = 300;
 MSChart1.Height = 300;
 MSChart1.Chart.Legends.Add(new Legend() { Name = "Legend1", Title="Legend title"});

 2.创建ChartArea对象，设置名称，轴标题，并将创建的ChartArea分配给MSChart：

 ChartArea chartArea1 = new ChartArea();
 chartArea1.Name = "ChartArea1";
 chartArea1.Axes[0].Title = "X name";
 chartArea1.Axes[1].Title = "Y name";
 MSChart1.Chart.ChartAreas.Add(chartArea1);

3.创建系列对象，设置图表类型，边框宽度，添加点并将系列分配给图表：

 Series series = new Series("sample");
 series.ChartType = SeriesChartType.Line;
 series.BorderWidth = 2;
 series.Points.Add(new DataPoint(0, 1));
 series.Points.Add(new DataPoint(1, 2));
 series.Points.Add(new DataPoint(3, 5));
 series.Points.Add(new DataPoint(4, 8));
 
 MSChart1.Chart.Series.Add(series);

 4.将创建的MSChart分配给DataBand：

Report report = new Report();
report.Load("ok.frx");
DataBand db = report.FindObject("Data1") as DataBand;
 
MSChart1.Parent = db;

完整的代码段：

 MSChartObject MSChart1 = new MSChartObject();
 MSChart1.Width = 300;
 MSChart1.Height = 300;
 MSChart1.Chart.Legends.Add(new Legend() { Name = "Legend1", Title="Legend title"});
 
 ChartArea chartArea1 = new ChartArea();
 chartArea1.Name = "ChartArea1";
 chartArea1.Axes[0].Title = "X name";
 chartArea1.Axes[1].Title = "Y name";
 MSChart1.Chart.ChartAreas.Add(chartArea1); 
 
 Series series = new Series("sample");
 series.ChartType = SeriesChartType.Line;
 series.BorderWidth = 2;
 series.Points.Add(new DataPoint(0, 1));
 series.Points.Add(new DataPoint(1, 2));
 series.Points.Add(new DataPoint(3, 5));
 series.Points.Add(new DataPoint(4, 8));
 
 MSChart1.Chart.Series.Add(series);
 
 Report report = new Report();
 report.Load("ok.frx");
 DataBand db = report.FindObject("Data1") as DataBand;
 MSChart1.Parent = db;

 结果：
