Syntax
public class Report : Base, IFRSerializable, IParent
Remarks

The instance of this class contains a report. Here are some common actions that can be performed with this object:

  • To load a report, use the Load(String) method or call static FromFile(String) method.
  • To save a report, call the Save(String) method.
  • To register application dataset for use it in a report, call one of the RegisterData methods.
  • To pass some parameter to a report, use the SetParameterValue(String, Object) method.
  • To design a report, call the method.
  • To run a report and preview it, call the method. Another way is to call the Prepare() method, then call the method.
  • To run a report and print it, call the method. Another way is to call the Prepare() method, then call the method.
  • To load/save prepared report, use one of the LoadPrepared and SavePrepared methods.
  • To set up some global properties, use the Config static class or component that you can use in the Visual Studio IDE.

The report consists of one or several report pages (pages of the ReportPage type) and/or dialog forms (pages of the type). They are stored in the Pages collection. In turn, each page may contain report objects. See the example below how to create a simple report in code.

Examples

This example shows how to create a report instance, load it from a file, register the application data, run and preview.

Report report = new Report();
report.Load("reportfile.frx");
report.RegisterData(application_dataset);
report.Show();

This example shows how to create simple report in code.

Report report = new Report();
// create the report page
ReportPage page = new ReportPage();
page.Name = "ReportPage1";
// set paper width and height. Note: these properties are measured in millimeters.
page.PaperWidth = 210;
page.PaperHeight = 297;
// add a page to the report
report.Pages.Add(page);
// create report title
page.ReportTitle = new ReportTitleBand();
page.ReportTitle.Name = "ReportTitle1";
page.ReportTitle.Height = Units.Millimeters * 10;
// create Text object and put it to the title
TextObject text = new TextObject();
text.Name = "Text1";
text.Bounds = new RectangleF(0, 0, Units.Millimeters * 100, Units.Millimeters * 5);
page.ReportTitle.Objects.Add(text);
// create data band
DataBand data = new DataBand();
data.Name = "Data1";
data.Height = Units.Millimeters * 10;
// add data band to a page
page.Bands.Add(data);

Remarks

This property contains pages of all types (report and dialog). Use the is/as operators if you want to work with pages of ReportPage type.

Examples

The following code demonstrates how to access the first report page:

Parameters

Gets the collection of report parameters.

Declaration
public ParameterCollection Parameters { get; }
Property Value
Type Description
ParameterCollection
Remarks

Parameters are displayed in the "Data" window under the "Parameters" node.

Typical use of parameters is to pass some static data from the application to the report. You can print such data, use it in the data row filter, script etc.

Another way to use parameters is to define some reusable piece of code, for example, to define an expression that will return the concatenation of first and second employee name. In this case, you set the parameter's Expression property to something like this: [Employees.FirstName] + " " + [Employees.LastName]. Now this parameter may be used in the report to print full employee name. Each time you access such parameter, it will calculate the expression and return its value.

You can create nested parameters. To do this, add the new Parameter to the Parameters collection of the root parameter. To access the nested parameter, you may use the GetParameter(String) method.

To get or set the parameter's value, use the GetParameterValue(String) and SetParameterValue(String, Object) methods. To set the parameter's expression, use the GetParameter(String) method that returns a Parameter object and set its Expression property.

Password

Gets or sets the report password.

Declaration
public string Password { get; set; }
Property Value
Type Description
System.String
Remarks

When you try to load the password-protected report, you will be asked for a password. You also may specify the password in this property before loading the report. In this case the report will load silently.

Password-protected report file is crypted using Rijndael algorithm. Do not forget your password! It will be hard or even impossible to open the protected file in this case.

PreparedPages

Gets a pages of the prepared report.

Declaration
public PreparedPages PreparedPages { get; }
Property Value
Type Description
PreparedPages

ReferencedAssemblies

Gets or sets an array of assembly names that will be used to compile the report script.

Declaration
public string[] ReferencedAssemblies { get; set; }
Property Value
Type Description
System.String[]
Remarks

By default this property contains the following assemblies: "System.dll", "System.Drawing.dll", "System.Windows.Forms.dll", "System.Data.dll", "System.Xml.dll". If your script uses some types from another assemblies, you have to add them to this property.

ReportInfo

Property Value
Type Description
ReportInfo

ReportResourceString

Gets or sets the resource string that contains the report.

ScriptRestrictions

Gets or sets a set of permissions that will be restricted for the script code.

Declaration
public PermissionSet ScriptRestrictions { get; set; }
Property Value
Type Description
System.Security.PermissionSet
Remarks

Since the report script is compiled into .NET assembly, it allows you to do ANYTHING. For example, you may create a script that will read/write files from/to a disk. This property is used to restrict such operations. This example shows how to restrict the file IO operations in a script:

using System.Security;
using System.Security.Permissions;
...
PermissionSet ps = new PermissionSet(PermissionState.None);
ps.AddPermission(new FileIOPermission(PermissionState.Unrestricted));
report1.ScriptRestrictions = ps;
report1.Prepare();

ScriptText

Gets or sets the report script.

Declaration
public string ScriptText { get; set; }
Property Value
Type Description
System.String
Remarks

The script contains the ReportScript class that contains all report objects' event handlers and own items such as private fields, properties, methods etc. The script contains only items written by you. Unlike other report generators, the script does not contain report objects declarations, initialization code. It is added automatically when you run the report.

By default this property contains an empty script text. You may see it in the designer when you switch to the Code window.

If you set this property programmatically, you have to declare the FastReport namespace and the ReportScript class in it. Do not declare report items (such as bands, objects, etc) in the ReportScript class: the report engine does this automatically when you run the report.

Security note: since the report script is compiled into .NET assembly, it allows you to do ANYTHING. For example, you may create a script that will read/write files from/to a disk. To restrict such operations, use the ScriptRestrictions property.
