Drag & Drop in a treeGrid

[palgaz]

Hi,
Please is there anyway to get the source parent and the destination parent on dropping an object into a new destination ?
Thank you,

And also I have an other question, it's possible to do somes controles on dropping an object. For exemple check if the object is intanceof a SubType, if yes, then drop, else cancel the drop event

I've got the exact same question and I didn't fin anyway to do it.

I found a kind of solution in another post.

You must override showFeedback in your TreeGridDropTarget.

Then, in the method, you can use

com.sencha.gxt.widget.core.client.tree.Tree.TreeNode<? extends BaseDto> item = super
                            .getWidget().findNode(
                                    event.getDragMoveEvent().getNativeEvent().getEventTarget().<Element> cast());

to find the target element, and if you want to forbid the drop, instead of calling the super you call :

// forbid the drop
                        status = -1;
                        activeItem = null;
                        appendItem = null;
                        Insert.get().hide();
                        event.getStatusProxy().setStatus(false);
