Gantt task predecessor is not working in resourceView

[xia]

Hi syncfusion supporter

I'm flowing the user guide to set the task relationship with predesessorMapping, and it's still not working.

My purpose is when you drag a task, the other task who has a relationship with that will be shift if the dragging task endDate time was dragged above others.

I know the connector between the tasks are not shown in the resource view, but it's OK, all I need is to see the interaction between these tasks.

Here is my demo -- https://jsplayground.syncfusion.com/f2tsjpwv

Sorry, my platform is JavaScript - EJ 1

Hi Xia, 

 

We analyzed the provided sample and we note that you set taskSchedulingMode as manual. When this property is set as manual the dates are not validated automatically based on the predecessor value. 

We can validate the dates automatically for the manual tasks by enabling the property validateManualTasksOnLinking.  

We can also validate the dates based on the predecessor values by setting the property taskSchedulingMode as auto. Please find the below code example. 

 

 

$("#resourceGantt").ejGantt({ 

     //taskSchedulingMode: ej.Gantt.TaskSchedulingMode.Auto, 

     taskSchedulingMode: ej.Gantt.TaskSchedulingMode.Manual, 

     validateManualTasksOnLinking: true, 

     //... 

}); 

 

Please find the below sample and documentation link.
