A Report Writer Control/Component by Telerik Inc.

Report parameters
Advanced, easy to use report parameters is one of the key highlights of the upcoming Q2 2007 release of Telerik Reporting. With the help of expressions (which can be used throughout a report definition to control content or appearance), report parameters can be used to specify the data to use in a report, connect related reports and subreports, modify presentation, filter data, control sorting and grouping, even change text box properties.

Fine-grained CSS-like styling
Telerik Reporting introduces a new, advanced, and much enriched styling mechanism through its build-in styling model, which closely follows CSS specifications. This model provides for quicker and very fine-grained visual customization of all reporting controls, all in the Visual Studio designer. This CSS-like mechanism offers full control over the item’s background, images, colors, borders, styles, paddings, etc.

You can assign styles to one or more reporting items by using the known CSS selectors: Type, Attribute, Style, and Descendant. Styles can also be applied globally and then saved to an external file for later use. If extra control over visual appearance is needed, cascading styles can be applied manually. See online demo

Extensive data source support
You can hook Telerik Reporting to any data source of your choice: all OLE DB providers (SQL Server, MySQL, Oracle, etc), Business Objects, MS Access, XML, Web Services, and even to a file.

Rich set of measurement units
A typical challenge in report design is the precise layout and sizing of elements for the purposes of proper printing and viewing in different formats. Telerik Reporting supports a variety of measurement units, which can be used for any element, including borders, padding, and even font sizes. Examples:
Font.Size=1cm
BorderWidth.Left=2mm
You can also use combinations of different measurement units where appropriate. A default report measurement unit allows you to quickly enter dimensions and positions without specifying the unit.

True Printing through the Web Viewer
Telerik Reporting does not depend on the browser's printing capabilities anymore, instead it uses its own paging and rendering.

User defined functions
You can write custom code that is used in expressions throughout a report thus extending the built-in functionality of the reporting engine to infinity. User defined functions are public static methods (shared in Visual Basic.NET), defined per report, and are available in both runtime and design time.

"Report Wizard" with themes and templates
The "Report Wizard" provides a codeless way for creating reports. Simply start it, select your data source, design the layout, and style your report through the provided templates in true click-and-go fashion.

Windows and Web report viewers
For complete control over viewing reports, the Telerik Reporting offers Windows Forms and Web Viewers, which guarantees that you will always get the same look and feel of your reports. Both viewers are also available within VS2005 with individual design-time support

Conditional formatting builder
Design your reports with the help of the new Conditional Formatting feature much like you would do in Microsoft Excel©.

Integrated expression builder
Parameters can be created and/or set through the intuitive Expression Builder, where you also set a specific filter clause. There is no need to write code, nor event handlers. Full control over conditional formatting, grouping, filtering, and even sorting is achieved with a few mouse clicks.

Visual Studio-identical datasource wizard
Telerik Reporting offers an advanced Data Source Connection Wizard, much like the one in VS2005. The wizard gives you the ability to hook your report to any existing database of your choice, in an intuitive and codeless manner.

Format builder
Following established usability standards, Telerik Reporting now features an item Format Builder which will assist you in formatting report items in Microsoft Excel© fashion.

Report converters
Reuse your existing Crystal Reports and Active Reports* with the help of the intuitive Report Converter Wizard. When creating a new report Telerik Reporting automatically detects whether you have Crystal Reports or Active Reports installed on your machine and guides you through the conversion process.
