RichTextBox supports both types of spell-checking using the C1SpellChecker component.

Insert new tables, rows and columns with the click of a button. Specify individual cell borders, sizes and text alignments. You can even merge cells and convert plain text to tables just like in Microsoft Word.

The C1RichTextBox toolbar ships localized in several languages, and new languages can be added by developers.

C1Chart can be professionally designed with just two properties. It includes 12 built-in themes and 22 color palettes. Themes apply to the entire chart area while palettes apply to just the chart elements (bars, points, pie slices, etc). Combine themes with different palettes to make an endless combination of looks or customize them precisely in code and markup.

Enhance the end-user experience by allowing users to zoom, scale, and scroll the chart. Customize the actions by specifying how the user should perform them, such as by mouse drag or key input.

Stack multiple plot areas horizontally and vertically. Just specify which data series belongs in which plot area to increase readability and analysis of multiple collections, while sharing common chart parts such as axes, legends and titles.

C1Chart gives you many axis options such as time display, logarithmic scales, axis scrolling, custom axis labels and support for multiple axes. Display multiple, dependent axes on the top, bottom, left, or right of the chart by simply adding to the chart's Axes collection.

Combine multiple, different chart types into one chart. Just set the ChartType property on each data series to achieve your desired combination.
