I would like to use RAD controls for silverlight in our workflow designer. Users need to (1) drag the source activities from the draggable list to the sequential activity tree, (2) reorder them within the tree.
The default drag&drop within the tree is OK, and it has 3 visual objects: (1) DragCue showing both source icon and label; (2) horizontal line; (3) Label describing the target location (before, in or after the item).
The default drag&drap between list and tree has only 2 visual objects: (1) DragCue showing source icon; (2) ArrowCue. It should have consistent Cues and behavior as that of drag&drop within the tree.
I am thinking the following steps:
(1) once the mouse reach the tree, create a temp tree item,
(2) automatically complete the first drag&drop between the two controls, and start the drag&drop within the tree.
Do you have even simpler approach to adding horizontal line and description label?
