Vue DataGrid - rowDragging

allowDropInsideItem

Allows users to drop a row inside another row.

Selector: allow-drop-inside-item

Type:

Default Value: false

This property also requires that you handle the change of hierarchy in code. If a row is dragged within a single component, use the onReorder handler. If the row is dragged from one component to another, use the onAdd and onRemove handlers.

allowReordering

Allows row reordering using drag and drop gestures.

Selector: allow-reordering

Type:

Default Value: false

This property limits row reordering to the UI and does not affect the data source. You should also handle the effects of the drag and drop to the data source in code. If users reorder rows inside a single component, implement the onReorder handler.

For information on drag and drop between components, refer to the group topic.

filter
