Feature Highlights

• Data binding – the control can be bound to a wide variety of data sources, such as Objects, Collections, XML, WCF services and more

ChartView: Minor Ticks and Stripes Support

If you need to provide a more punctual view of the ticks in an axis, you can utilize the minor ticks support of RadChart. With it, you can define the number of minor ticks to be displayed between major ticks. Minor ticks can be heavily customized with the available API to define the number of minor ticks between major ones, the tick length, offset from the major tick, the tick template and style

In addition to the minor ticks, we have also added support for grid stripes. Stripes are the visual representation of the minor ticks in the chart area and can be used to display where the minor ticks are, for the user to easily spot the value of a certain tick and compare it to a data point on the chart. Stripes support defining the stripe visibility, style, dash array and more.

SpreadProcessing: Insert and Delete Comments

The latest addition to the SpreadProcessing library is the ability to insert and delete comments in excel files. This functionality allows you to add information about a cell, reply to a comment or delete one. Information such as the creation date, author and whether the comment is resolved is also readily available.

SpreadProcessing: Cell References

SpreadProcessing now supports Absolute, Relative and Mixed cell references to entire columns and rows, e.g., $1:$2 and A:D. These come in handy when you need to work with a range of cells.

PdfProcessing: Support for Type 3 Fonts

According to the PDF standard, Type 3 fonts can contain lines, areas, shares of gray, images, graduated fills or variable stroke width. This makes them quite useful for displaying logos or barcodes. Should you need to embed Type 3 fonts into a PDF file or to manipulate a file that uses such font types, with the RadPdfProcessing library for WinForms you can do it all.
