Hello, Our company’s project needs the following functionality: after dropdown in RadDropDownTree is closed, an event will fire - only ONCE – with all checked nodes. Currently, NodeCheck event fires immediately for each node checked. And, onEntryAdded event occurs after the dropdown is closed, but it is fired for each node checked. Our project involves a lot of data. Therefore, many nodes can be checked by the user. It is unpractical that the event will be fired for each node checked, as this will harm our project’s functionality and performance. Thanks, Daniel. .Net Programmer at ISR Corp.
