Built-in Style Rules
There are several built-in style rules for each taskbar type (GC.Spread.Sheets.GanttSheet.TaskbarStyleRuleName).
durationOnly
durationOnlyMilestone
finishOnly
finishOnlyMilestone
manualMilestone
manualProgress
manualSummary
manualTask
milestone
progress
projectSummary
startOnly
startOnlyMilestone
summary
task
The corresponding style can only be set for a single task if a primary key exists.
You can get the style of a task and change its style properties like so:
/*REPLACE_MARKER*/
/*DO NOT DELETE THESE COMMENTS*/
