Hi Daniel,
Thank you for writing. You can disable expand/collapse animation by setting RadTreeView
ExpandAnimation to
None. You can also disable the other animations by modifying one of the existing themes or creating an entirely new theme with our
Visual Style Builder application. I would ask you to explain in more detail how you are using RadTreeView. Are you loading a lot of nodes? Do you have images in the nodes? I am looking forward to your reply.
Sincerely yours,
Victor
the Telerik team
