AllowedEffects Property
Gets or sets the allowed effects for the drag operation.
public Avalonia.Input.DragDropEffects AllowedEffects { get; set; }
Remarks
This property can be used to control what operations (move, copy, etc.) are permitted during the drag operation. By default, when Avalonia.Controls.TreeDataGrid.AutoDragDropRows is enabled, this is set to Avalonia.Input.DragDropEffects.Move. Setting this to Avalonia.Input.DragDropEffects.None will cancel the drag operation.
Models Property

public System.Collections.Generic.IEnumerable<object> Models { get; set; }
Remarks
These are the underlying data models for the selected rows, not the visual row elements.
