Add more context information to criteriaScript in GridDropTargetConnector (#11321)
* Add more context information to criteriaScript in GridDropTargetConnector
When using drag and drop in Grids and TreeGrids a criteriaScript can be specified.
However, this criteriaScript only gets an event as input parameter.
It would be helpful if the criteriaScript would get more information:
- the DropLocation
- the targetElement which is used as a base for the DropLocation
This change provides a protected method in DropTargetExtensionConnector
which decides, if the drop is allowed by the criteriaScript.
This method is overriden in GridDropTargetConnector to
provide the both parameters dropLocation and targetElement.
* add Test UI for criteriaScript with targetElement and dropLocation
* add some description for the Test UI
