Occurs when a new Node should be provided for AdvancedTree's NodeCollection.
The event handler receives an argument of type NodeAddingEventArgs containing data related to this event. The following NodeAddingEventArgs properties provide information specific to this event.
| Property | Description |
|---|---|
| Cancel | Gets or sets a value indicating whether the event should be canceled. |
| Level | Gets the depth of a node that is about to be added. |
| Node | Sets a node that will be added into AdvancedTree's NodeColection. |

Once you call the LoadDataManually method, AdvancedTree fires this event regularly for you to provide it a Node object filled with data. The arguments for this event is derived from CancelEventArgs. You have to set the Cancel property in the event handler to true to stop loading more data. If DelayLoad is set to true, the event stops firing as soon as the nodes fill up AdvancedTree's client area. However, as soon as the user scrolls down to see more nodes, the event starts firing again for the user to provide additional Node objects to be added into the NodeCollection.
