its not really the way to do it. First you need to disable he drag
drop ,drag enter and drag move on trees so that is does not call the
default functions when you are dragging an item from the datagrid,
then you need to implement the following :
dropEnabled="false" /*Set the property of the tree*/
dragEnabled="false" /*Set the property of the tree*/
dragMoveEnabled="false" /*Set the property of the tree*/
dragEnter="onDragEnter(event)" /*Implement this
function*/
dragDrop="onDragDrop(event)" /*Implement this
function*/
dragOver="dragOver(event)" /*Implement this function*/
