In the Gantt control, While performing edit actions or dynamically change dataSource, the timeline gets refreshed. When zoomToFit toolbar item is clicked and perform editing actions or dynamically change dataSource, the timeline gets refreshed. So that, the timeline will not fit to the project any more.
We can maintain zoomToFit
after editing actions(cell edit,dialog edit,taskbar edit) by using fitToProject
method in actionComplete
and taskbarEdited
event.

We can maintain zoomToFit
after change dataSource dynamically, by calling fitToProject
method in dataBound event.
