#Treeview angularjs code
In case of our example, we are adding code which changes the icon of parent of dragged object (item or row).Įach item or row object has an icon field which accepts a CSS class name. By handling dragDrop event for example, you can set custom conditons and when they are met you can invoke a custom operation. You can modify this in your code and add any custom functionality.

Depending on whether there are child objects the icon is changed to folder icon, if there are no chidren, icon changes to a file icon. You may also notice from above demonstration during drag drop operations, that icon of parent items and rows changes. Handling Drag Drop Events to Change Item Icon In both cases, all data is sustained, only in case of dropping a tree item, because there are no cells for item objects, they are internally created by the built-in functionality of the Tree Grid. When row is dropped, an item is created using only the row text, and cells that belong to the row are not displayed. In similar way, when row from Tree Grid is dragged over TreeView space, a tooltip will appear stating the target item and the position at which dragged row will be dropped.

Note The tooltip icon changes depending on drop position. In this process when item is dropped, a row is automatically created using the data from the tree item.
