SortOrder=Ascending + Drag'n'Drop

[Brian]

This (to me) seems to be a bit of an odd one.

I have a RadTreeView, if I set the SortOrder to None,  then Drag'n'Drop features work .. as i'd expect.

If I set the SortOrder to Ascending;  then Drag'n'Drop appears to be switched off?


Am I missing something?   Is there a setting I need,  or do I have to either implement my own custom sorting or custom drag'n'drop?

Thanks
Brian.

Hello Brian,

Thank you for writing.

The observed behavior is the normal behavior, since when you have a sorted the tree, the drag and drop operation does not make sense. You cannot change the position of a node in a sorted tree, since it has to be in a certain position according to the sort order.

I hope that you find this information useful.

Does that mean, that it is impossible to drag item into node and expect this item to drop into "sorted" position?

Hi David,

I have just tested this behavior with our latest version and it does work as you described. One can drag and drop the nodes, and once a node is dropped, it get sorted right away. See attached video.

I hope that you find this information useful. Should you have any other questions, do not hesitate to contact us.
