Drag from Grid to Scheduler

Hello,

I’m struggeling with dragging some data from the grid onto the scheduler.
In the grid I have job records that I want to schedule by dragging them onto the scheduler.
Grid and scheduler are both attached to a layout object.
Also I want to be able to drag data from external source onto the scheduler.
This part is already working - I have an “ondrop” function in the “scheduler-here” div-container.
Dropping some text from external source works okay.
When dragging from the grid I only see the dragged row (the first column of the row) while dragging, but when I drop it, nothing happens. I guess the dragdata format is not “text” - how can I change it?

Thanks,
Thomas
