How to implement row-up and row-down in gantt view.

Hello,

Is there any way we can implement a feature/function by which we can move a row up or down when button is clicked or context menu action is clicked.

thank you.

In the latest sandbox build (2023.1.5542), there are new methods added that will let you scroll as needed:

getScrollX()
getScrollY()
setScrollX()
setScrollY()
scrollToTask()

You can scroll down one row using setScrollY():

dp.setScrollY(dp.getScrollY() + dp.taskHeight);

No, actually I meant moving. Suppose you click a button move up, it will move the task one row up just like the taskMoving( that we do by dragging the task).

Sorry for the confusion.

You can do this by changing the order of tasks in the data source (it's stored in dp.tasks.list). Then call update() to apply the changes.
