Firing Command Events from Code

In some specific cases you may want to raise command events (like Select/Sort/Page/etc.)in code rather than clicking buttons which are placed inside RadTreeList. For such type of situations TelerikRadTreeList exposes the FireCommandEvent(eventName, eventArgs) method which can be called from the items related to the respective operation.

The table below explains the parameters which you can pass to that method to fire corresponding commands:
