1.如何在WPF應用程序中使用FastReport.Net控件？編程

您應該爲此使用WindowsFormsHost控件：url

0）在FastReport.dll上添加引用；spa

1）若是要使用PreviewControl，則將屬性添加到Window（Page）標記中：xmlns：fr =「 clr-namespace：FastReport.Preview; assembly = FastReport」，xmlns：fr1 =「 clr-namespace：FastReport.Design; assembly = FastReport」-if DesignerControl;.net

2）將WindowsFormsHost標記添加到您的XAML標記中：code

<WindowsFormsHost HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Grid.Column="0" Grid.ColumnSpan="3">
</WindowsFormsHost>

3）將子級添加到WindowsFormsHost中：<fr：PreviewControl> </ fr：PreviewControl>或<fr1：Designer> </ fr1：Designer>。orm

完整的標記應以下所示：

<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.如何以編程方式設置Format的值？

您能夠使用如下代碼在腳本或項目中執行此操做：

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

而後：

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

3.如何在MSChartObject中建立帶有間隙的行？

您應該建立基本的System.Windows.Forms.DataVisualization.Charting.Series對象，並在此處建立行。以後，應爲MSChartObject基本圖表分配建立的系列（MSChart1.Chart.Series.Add（series）;）不要忘記在「報表」->「腳本」菜單和命名空間System.Windows.Forms中添加 System.Windows.Forms.DataVisualization.dll。 .DataVisualization.Charting。

帶有間隙的線的示例：

.
.
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);
 
 }
 }
}

結果：

4.如何從代碼建立MSChartObject？

1.建立新的MSChart對象，設置寬度，高度和圖例：

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

2.建立ChartArea對象，設置名稱，軸標題，並將建立的ChartArea分配給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.建立系列對象，設置圖表類型，邊框寬度，添加點並將系列分配給圖表：

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.將建立的MSChart分配給DataBand：

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

完整的代碼段：

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;
