Hi Alfred,
Greetings from Syncfusion.
To render gantt chart as specified by the datasource schedule, you can set the 'autoCalculateDateScheduling' property to false. No need to use 'IsManual' or 'TaskMode' properties.
Note: Enabling this property means that no internal validation will be performed, and the taskbars will be rendered based solely on the data provided in the data source.
Code-Snippet:
autoCalculateDateScheduling: false, |
Sample - 3l6b3x (forked) - StackBlitz
If we have misunderstood your query, please provide us with more details.
Regards,
Sridharan
