# NodeDrop

When a Node is dropped onto another Node, between other Nodes or onto an HTML element the **NodeDrop** event fires. The **RadTreeNodeDragDropEventArgs** provides properties for the source and destination Nodes:

* **SourceDragNode**: The Node being dropped.

* **DestDragNode**: The Node being dropped onto.

* **DraggedNodes**: A collection of **RadTreeNodes** that are being dragged. This could be useful when **MultipleSelect** is **True**.

* **DropPosition**: Indicates the relationship of the Nodes being dropped and will be a **RadTreeViewDropPosition** enumeration value **Above**, **Below** or **Over**.

* **HtmlElementID**: The **ID** of the HTML element that the Node is being dropped onto.

See [Drag and Drop Overview](https://www.telerik.com/products/aspnet-ajax/documentation/controls/treeview/drag-and-drop/overview) for more information.

```C#

    e.DestDragNode.Nodes.Add(e.SourceDragNode);
} 		
```

```VB.NET
