TPlanner moving Items


I am working on moving items with the mouse. My planner doesn't make use of the cells but we create items to become our cells.
Is it possible to block the movement of an item on empty cells ?
In other words, I wish the items could be movable only if it is on other items.

Thank you in advance.

You can implement the OnItemMoving event. It is triggered during the moving with the coordinates where the item is being moved to. It has a var Allow parameter you can use to block the moving to certain cells if you want this.
