PROJECT DESCRIPTION
Hello,
i want to deactivate the before / after operation and allow only Inside operation (i use treeview drag and drop only to change a hierarchical order).
Is it possible ?
I tried to handle the preview ended operation but i don't know how to set my value to the element targeted.

Is it possible to have second operation with a keypress or other with dragging ? (like i want to have another operation when i drag and i have crontrol key pressed)

Thank you for all !!!

Hello Ludovic Alcala,

Yes, it is possible to disable before / after dropping by handling the DropQuery event and specifying that if the DropPosition is Before or After the drop should not be possible.

There is a help articles that covers this here:

http://www.telerik.com/help/silverlight/radtreeview-how-to-enabled-drop-inside-only.html

If you would like to do something specific depending on a pressed key, you can check the Keyboard.Modifiers and decide what to do depending on the modifiers. A good event to handle there will be either the treeView.DragEnded or RadDragDropManager.DropInfo.

This article details implementing copy-drag:

Hopefully this will help you,

Kind regards,
