onBeforeExternalDragIn

fires before some element starts to be dragged into the scheduler from an outside DHTMLX component (only with dnd extension enabled)

source	HTMLElement	an HTML element that will be dragged into the scheduler
dhtmlx	object	a global DHTMLX object
tArea	HTMLElement	an HTML object of the scheduler's data area
tNode	HTMLElement	the target scheduler's HTML object (a column in the Day view, a section in the Timeline view, etc.)
e	Event	a native event object

boolean

defines whether the default action of the event will be triggered (true) or canceled (false)

Example

scheduler.attachEvent("onBeforeExternalDragIn",function(source,dhtmlx,tArea,tNode,e)
{
    //any custom logic here
    return true;
});

The event is blockable. Return false and the external element won't be dragged to the scheduler.
