Where GUI elements are implemented using pseudographics) using a mouse or touch screen.

The method is implemented by “capturing” (by pressing and holding the main ( first, usually the left mouse button) of an object displayed on the computer screen, programmatically available for such an operation, and moving it to another place (to change the location) or “throwing” it onto another element (to call the corresponding action provided by the program). In relation to windows (also capable of moving in a similar way) this term is not usually used.

Basic actions and the simplest examples of drag-and-drop actions are: moving an object, moving an object from panel to panel, although in modern operating systems Drag-and-drop has become widely used and is one of the main ways to interact with a computer in a graphical user interface.

Objects to move can be the following interface elements: Desktop icons, floating toolbars, program shortcuts in the Taskbar (starting with Win XP), TreeView elements, text string, DataGridView cell., also OLE elements. Objects can move both within a certain certain area, within one window, between panels of the same window, and between different windows.

The drag event must be triggered by some user action. Most often, this action is pressing the left mouse button on an element (this event is called MouseDown), which can be moved in its container. Some components have their own drag-n-drop start events - for example, TreeView has an ItemDrag event.
