TdxGanttControlTaskBaseline.Duration Property

Specifies the baseline’s duration, in ISO 8601 format.

Declaration

property Duration: TDuration read; write;

Property Value

Type	Description
TDuration	A baseline’s duration specified as a string.

Remarks

Use this property to specify the duration of a task‘s baseline as follows: PT(N)H(N)M(N)S.

A baseline’s duration is calculated as the difference between its start and finish dates. The duration defines the baseline bar’s length in the chart.

Note

The baseline bar’s length is updated every time a user changes the duration or its measurement units.

Specify Baseline Duration

The table below describes all characters required to specify the baseline’s duration:

Value	Description	Example
P	Period and time designation. You should use this construction to denote task duration; otherwise, the control throws an exception.	‘PT8H22M6S’ – eight hours, twenty-two minutes, and six seconds.
T
N	An integer value.
H	Hours, minutes, and seconds. Tip To omit a time unit, specify 0 before it.
M
S

Implementation Details

The control ignores the baseline’s Duration property value until you do any of the following:

• Specify the property value explicitly

• Assign the duration to the task associated with the baseline and then call the AssignCurrentValues procedure

Note

You should call the baseline’s AssignCurrentValues procedure every time you change the associated task’s settings. Otherwise, the baseline settings are not updated.
