Diagrams linking controls

[VCMANZO]

Hello All

I need to create a Diagram in a Form… Like Gantt diagrams or SQLServer Relations Diagrams.

The scenario is like this:

I have two Listbox controls (LB1 and LB2) and I want to relate graphically both of them doing some drag and drop…

Let’s say I select one element on LB1 and Drag that element to link it/overlap it to one element in LB2. What should happen, is that a Line should be drawn linking LB1 and LB2 by the elements just related…

I have been investigating the dragdropeffects Enumeration, and there is a LINK value but I don’t know how to use it and if is the solution to my issue….

Can anybody suggest/Help?

Regards,
VCM

Sorry I haven't tried anything like that and I'm not really good at drawing. Or is your question about the drag and drop?

I think we can split the question in 2 topics...

1) How can a relate/link two items in 2 list boxes (with drag and drop if possible)?

2) How can a draw a line to see the relation in point 1?
