Span Planner Control
Used to design horizontal spans of various colours. Similar to a Gantt Chart,
but it doesn't handle dependencies. The main thing I've done with it is to make
a Day Planner:
It also comes with a funky Legend Control:

SpanPlanner
These are just the more interesting properties & methods.Headers
A collection of SpanHeaders. Each of these has a BackColor (which can be
Color.Empty). This BackColor is used to set up the alpha background you see
above. They also have Text and Width properties.
Rows
Contains a Collection of SpanRows. These also have BackColor and Text
properties. It also contains a Spans property which hosts the pretty spans you
see above.
SpanTool
This contains an object that implements ISpanTool. Basically the thing
that creates the spans that are added to the planner. It's a Factory
class. There are two implementations of ISpanTool: ColorSpanTool and
LegendSpanTool.
Key
Contains the public key that is used to check the license and policy
signatures.
BuildHourlyHeaders
Generates the headers in the screenshot.
BuildWeeklyRows
Generates the rows in the screenshot.
Span Object
Represents a span being designed. Note that when spans are overlapped they do one of two things: merge or join. A merge only happens when the spans have the same brushes and pens. The two spans are merged into one. In a join (which happens when the spans cannot merge), one span is pushed out of the way of the other.operator explicit DateTime
Used when you created the SpanPlanner using BuildHourlyHeaders. Converts the
start of the span to a DateTime (always relative to DateTime.Today).
operator explicit TimeSpan
Also used when the planner has hourly headers. This converts the duration
of the Span to a TimeSpan.
Legend Control
Contains a set of LegendItems to display. Have a look at the sample for how to interoperate the SpanPlanner with the Legend control.
