Task Scheduling
11 Jun 202424 minutes to read
The Gantt provides support for automatic and manual task scheduling modes. It is used to indicate whether the start date and end date of all the tasks will be automatically validated or not. taskMode is the property used to change the schedule mode of a task.
The Gantt control supports three types of mode. They are:
-
Auto: All the tasks are automatically validate. -
Manual: All the tasks are manually validate by the user. -
Custom: Both Auto and Manual tasks are render by mapped from data source.
NOTE
The default value of
taskModeisAuto.
Automatically scheduled tasks
When the taskMode property is set as Auto, the start date and end date of all the tasks in the project will be automatically validated. That is, dates are validated based on various factors such as working time, holidays, weekends and predecessors.

Manually scheduled tasks
When the taskMode property is set as Manual, the start date and end date of all the tasks in the project will be same as given in the data source. That is, dates are not validated based on various factors such as dependencies between tasks, holidays, weekends, working time. We can restrict this mode in predecessor validation alone. That is, we can automatically validate the dates based on predecessor values by enabling the validateManualTasksOnLinking property.

Unscheduled tasks
Unscheduled tasks are planned for a project without any definite schedule dates. The Gantt control supports rendering the unscheduled tasks. You can create or update the tasks with anyone of start date, end date, and duration values or none. You can enable or disable the unscheduled tasks by using the allowUnscheduledTasks property. The following images represent the various types of unscheduled tasks in Gantt.
| Taskbar state | Auto | Manual |
|---|---|---|
Start Date Only |
 |
 |
End Date Only |
 |
 |
Duration Only |
 |
 |
Milestone |
 |
|
NOTE
A milestone is a task that has no start and end dates, but it has a duration value of zero.
Define unscheduled tasks in data source
You can define the various types of unscheduled tasks in the data source as follows

allowUnscheduledTasksproperty is set to false, then the Gantt control automatically calculates the scheduled date values with a default value of duration 1 and the project start date is considered as the start date for the task.
Working time range
In the Gantt control, working hours for all days of a project can be defined by using the dayWorkingTime property. Based on the working hours, automatic date scheduling and duration validations for a task are performed.
The following code snippet explains how to define the working time range for the project in Gantt.

NOTE
- Individual tasks can lie between any time within the defined working time range of the project.
* ThedayWorkingTimeproperty is used to define the working time for the whole project.
Working time range for specific day in a week
In the Gantt control, weekWorkingTime property enables you to specify different working hours for each day of the week in your Gantt chart. By configuring this property, you can ensure that tasks are only scheduled during defined working periods, avoiding non-working hours for that respective day.
The timeRange property of weekWorkingTime accepts multiple breakup in the working time as like dayWorkingTime property. This working time range will apply only to the working days defined in dayOfWeek property of weekWorkingTime.
The following code snippet explains how to define the week working time range for the project in Gantt. In the below sample working time range for Monday and Tuesday is set from 10 to 18.
@{
List<GanttDayWorkingTime> timeRanges = new List<GanttDayWorkingTime>();
GanttDayWorkingTime timeRange1 = new GanttDayWorkingTime()
{
From = 10,
To = 18
};
timeRanges.Add(timeRange1);

- By default working time range for all days will be

dayWorkingTimeandweekWorkingTimeare mapped, priority will be given toweekWorkingTimeproperty.- Default working time defined in
dayWorkingTimeproperty will be used for the days left out in theweekWorkingTimeproperty.- If a day is a holiday or non-working day and also initialized in

Weekend/Non-working days
Non-working days/weekend are used to represent the non-productive days in a project. You can define the non-working days in a week using the workWeek property in Gantt.

NOTE
By default, Saturdays and Sundays are considered as non-working days/weekend in a project.
In the Gantt control, you can make weekend as working day by setting theincludeWeekendproperty totrue.
Duration units
In Gantt, the task’s duration value can be measured by the following duration units,
- Day
- Hour
- Minute
In Gantt, we can define duration unit for whole project by using durationUnit property, when we defines the value for this property, this unit will be applied for all task which don’t has duration unit value. And each task in the project can be defined with different duration units and the duration unit of a task can be defined by the following ways,
- Using
taskFields.durationUnitproperty, to map the duration unit data source field. - Defining the duration unit value along with the duration field in the data source.
Mapping the duration unit field
The below code snippet explains the mapping of duration unit data source field to the Gantt control using the taskFields.durationUnit property.

Defining duration unit along with duration field
Duration units for the tasks can also be defined along with the duration values, the below code snippet explains the duration unit for a task along with duration value,
