Item Drag & Drop
This demo shows how to enable item drag and drop in the List UI component. You can reorder items or drag and drop them between two separate lists. Use the handles on the right side of items to initiate drag and drop.
The following steps describe how to configure this functionality:
-
Enable item drag and drop
Set the itemDragging.allowReordering to true. -
Add the lists to the same group
Set the group property of both UI components to the same value to allow a user to drag and drop items between them. -
Reorder list items in code
Use the onDragStart event handler to store the dragged item's data. When a user drops the item, the onRemove and onAdd functions allow you to remove the item from its initial position and add it to the new location.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
