# DragAndDropEventBase<T>

> Base class for drag and drop events.

## Definition

* **Type:** Class
* **Namespace:** [UnityEngine.UIElements](/engine/6000.5/script-reference/unityengine/uielements.md)
* **Assembly:** UnityEngine.UIElementsModule
* **Inherits from:** [MouseEventBase\<T>](/engine/6000.5/script-reference/unityengine/uielements/mouseeventbase1.md)
* **Implements:** [IDisposable](https://learn.microsoft.com/dotnet/api/system.idisposable), [IMouseEvent](/engine/6000.5/script-reference/unityengine/uielements/imouseevent.md), [IDragAndDropEvent](/engine/6000.5/script-reference/unityengine/uielements/idraganddropevent.md)

```csharp
public abstract class DragAndDropEventBase<T> : MouseEventBase<T>, IDisposable, IMouseEvent, IDragAndDropEvent where T : DragAndDropEventBase<T>, new()
```

## Remarks

Drag and drop events are only available on Editor-type Panels.

Refer to the [Drag-and-drop events](/engine/6000.5/manual/uitoolkits/uielements/uie-events/reference/uie-drag-events.md) manual page for more information and examples.
