Task

In this help article you can find helpful information on the different types of RadGantt tasks, their properties and methods.

Task Types

Depending on the TaskType property, the Task can be one of three types:

• Regular Task - regular task which can have assigned resources, links to predecessors, start date, end date,duration and percentage of completion.

• Summary - a grouping of child tasks. The Summary has a Start and End determined by the earliest Start and latest End of its child tasks. The percentage of completion is calculated based on the percentage of each child task. The Summary does not have links to predecessors, and can not be referenced as such by other tasks.

• Milestone - a regular task with zero duration.
