Public Property ImageIndex As Integer
| Type | Description |
|---|---|
| Int32 |
An integer value representing the zero-based index of the desired image within the TreeList.Painter.NodeDragImages collection.

Initially, the source image list contains only three standard images with 0 , 1 and 2 indices. However, you can modify the collection to add custom images to it. If you do this use the added image’s index instead, to display it in front of nodes when dragging.
The source image list can be accessed via the TreeList.Painter.NodeDragImages property.
The following code snippet (auto-collected from DevExpress Examples) contains a reference to the ImageIndex property.
