I have created a tree panel containing empty nodes(folder) and other nodes(folders) containing child nodes under them. When I drag drop a file from one folder to another folder containing child nodes under it, it is working as expected. But when I drag drop a file from one folder to another folder which is empty is throwing error.
I am using "beforeitemmove" event to handle drag drop. When I drag drop a file from one folder to another empty folder "itemexpand" event is being triggered before the control comes to "beforeitemmove" handler. Since Taget Folder is empty "item expand" method is throwing error.
How to avoid expanding target node when any item is drag-dropped to it?
Thanks in Advance
