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
You can get the style rule and change its style properties like so:
Configurable Style Properties
startShape: GC.Spread.Sheets.GanttSheet.TaskbarEndShape
startType: GC.Spread.Sheets.GanttSheet.TaskbarEndType
startColor: string
endShape: GC.Spread.Sheets.GanttSheet.TaskbarEndShape
endType: GC.Spread.Sheets.GanttSheet.TaskbarEndType
endColor: string
middleShape: GC.Spread.Sheets.GanttSheet.TaskbarMiddleShape
middlePattern: GC.Spread.Sheets.GanttSheet.TaskbarFillPattern
middleColor: string
leftText: string
rightText: string
topText: string
bottomText: string
insideText: string
Text properties like leftText support the data field name and column formula:
Custom Style Rules
You can create a custom style rule based on the base style rule class (GC.Spread.Sheets.GanttSheet.TaskbarStyleRule):
Then add your custom style rule to the taskbar style rule collection (GC.Spread.Sheets.GanttSheet.TaskbarStyleRules):
You can update an existing custom style rule:
