Fires when the Tree List control reloads all nodes.
The NodesReloaded event's data class is EventArgs.
Write a NodesReloaded event handler to perform specific actions when the control reloads all nodes. This can take place in the following cases:
- The associated data source has been changed. (A new value is assigned to the TreeList.DataSource or TreeList.DataMember property).
- Much of the associated data source's data has been changed.
