Drag grid item to another grid

[EduardoLuis]

Hey Edward. What a great job. Excelente and usefull implementación. Congratulaciones.

As promised here is the next version.
Added:
- support for Ctrl and Shift while dragging and dropping.
With the Shift key, you can move items by changing the position in the tree, with the Ctrl key we perform a copy operation.
- handling the context menu when dropping the right mouse button on tree # 2 (Copy / Move)
- handling the context menu of tree # 2 (on the tree item/node: Rename / Delete / Add as child ; in the empty tree space: Add New As Root )
- there is a new method for the tree: InsertItem
As I did not integrate this method with HMG sources, we call it as a function: _InsertItem (ControlName, FormName, cValue, nInsertPos, [aImage], [Id]).

Now you can build a tree using the context menu.

Enjoy.

We have many contribution code like this;

thanks to these successful participants.

Sadly adding this useful codes to the core of HMG not likely in the near future

there isn't a way adding them to next releases of HMG under a new section namely such "contributions"


Viva HMG, builder, developers, contributors, participants and followers

We have no leader now, who will create new versions.
It's really sad.

Thanks Edward for your great work!

A small bug fix when adding / inserting a node to the root of the tree.

In last sample, when I move Item 2.2.8 to Item 2.2.7 - look ok, but when I drag Item 2.2.7 to Item 2.2 (its parent - nothing should happened) Item 2.2.8 is lost

Sample for a tree that uses IDs.
Unfortunately, in this variant there are constraints based on the necessity of assigning new IDs when copying/adding tree elements. Also, you would need to give ID for elements dragged from other controls like textbox or from other trees, which is why these functionalities have been removed.
