Issue on drag a treeview's item from one to another

4 posts in this topic

Greetings!

I found a great TreeView's example here, and adapt to work with two treeviews.

But there are a issue and I have no idea to solve it.

Open the example, and drag one item from a treeview to other.

Sometimes in treeview origin does not show a item error/graphic error, but most of the time, there are a graphic error, it cannot delete a drag image of treeview.

If you drag a item in the same treeview, no error, its work fine.

If you drag from one to another, there are error.

Somebody can help-me, how fix it?

Best regards

Luigi

@Danyfirex, thank you for your reply.

 

I fix some redraws (not all).

And you can drag any item from one to another, and left on empty (root).

Sometimes it expand the write item, sometimes not.

If you begin drag a treeview item, from one to another treeview, if the item stay in the origem treeview, its show with correct name, when it moved to another treeview, the name its wrong, but, when you left, its fixed. This bug is only when you drag a item.

 

I want implement:

a] copy a node

b] context menu (delete, rename, create) 

c] define a rule: you can drag(create a copy) from on treeview for another, not inverse

 

This is a new code.
