Drag & Drop functionality has integrated support both by application and back-end application server.

Drag & Drop process activity diagram

The Drag & Drop operation behaves according to the model:

Drag & Drop for touch screens

Touch screens generally doesn't support Drag & Drop. There is a good reason not to used drag and move functionality because it would be confused with gestures. Even the using two or three fingers for Drag & Drop is not efficient on touch screens.

Framework supports Drag & Drop by overwriting the context menu functionality. Context menu is activated by long press or right-mouse click. When using the contextmenu event on drag able or droppable object, framework effectively simulates Drag & Drop. This. functionality even allows to store dragged object longer time and move it to another screen in the same window.
