This sample project shows the possibility of creating a report in runtime. After you create a report using the code, you can display it in the WPF viewer. For a start, initialize components:

public MainWindow()
{
	InitializeComponent();
}

All necessary actions can be done in the Button_Click() event of the application. In the first place create the new report object, register the data and synchronize it with the report dictionary:

private void Button_Click(object sender, RoutedEventArgs e)
{
	var report = new StiReport();

	// Add data to datastore
	var dataSet = StiJsonToDataSetConverterV2.GetDataSetFromFile(@"Data\Demo.json");
	report.RegData(dataSet);

	// Fill dictionary
	report.Dictionary.Synchronize();

...

Then we need to create the report components. First, add the Header Band to the report page with the Text component that will display the title:

...

	var page = report.Pages[0];
	
	// Create HeaderBand
	var headerBand = new StiHeaderBand();
	headerBand.Height = 0.5;
	headerBand.Name = "HeaderBand";
	page.Components.Add(headerBand);
	
	// Create text on header
	var headerText = new StiText(new RectangleD(0, 0, 5, 0.5));
	headerText.Text = "CompanyName";
	headerText.HorAlignment = StiTextHorAlignment.Center;
	headerText.Name = "HeaderText";
	headerText.Brush = new StiSolidBrush(System.Drawing.Color.LightGreen);
	headerBand.Components.Add(headerText);

...

Next, add the Data Band with the Text component to which add an expression. This expression combines the Line number and the CompanyName data column from the Customers data source:

...

	// Create Databand
	var dataBand = new StiDataBand();
	dataBand.DataSourceName = "Customers";
	dataBand.Height = 0.5;
	dataBand.Name = "DataBand";
	page.Components.Add(dataBand);
	
	// Create text
	var dataText = new StiText(new RectangleD(0, 0, 5, 0.5));
	dataText.Text = "{Line}.{Customers.CompanyName}";
	dataText.Name = "DataText";
	dataBand.Components.Add(dataText);

...

Finally, add the page Footer Band with the Text component which displays the text at the bottom of the page. Last action is a call of the WPF viewer which will build and display the report automatically:

...

	// Create FooterBand
	var footerBand = new StiFooterBand();
	footerBand.Height = 0.5;
	footerBand.Name = "FooterBand";
	page.Components.Add(footerBand);
	
	// Create text on footer
	var footerText = new StiText(new RectangleD(0, 0, 5, 0.5));
	footerText.Text = "Count - {Count()}";
	footerText.HorAlignment = StiTextHorAlignment.Right;
	footerText.Name = "FooterText";
	footerText.Brush = new StiSolidBrush(System.Drawing.Color.LightGreen);
	footerBand.Components.Add(footerText);
	
	report.ShowWithWpf();
}
