Dear support team,
I'm using the built-in create child on the TreeList, which is referenced hear. I just added the "createChild" to the list of commands. On the grid if I click the button the child is created. I can then update the cells, but once I click the update button, the actions are subsequently itemchange, sync, then remove. Of course, the newly created item is removed from the grid. My contact information has been changed, but not with Telerik, so use the below contacts.
