I've been experimenting with the TreeViewAdv samples. I noticed that the Data Binding Demo (and two other bound samples I was provided) is very slow when you try to expand and collapse the nodes of the tree. The other samples are okay.

Does anyone know of the cause or have any workaround for this?

(I'm using 7.4.0.20 in trial mode, C#, running on Win XP.)

Hi Ball,

By default the TreeViewAdv AnimationType is "Slide" and default AnimationSpeed is 1, This is the reason you are feeling that TreeViewAdv is expanding slow. It is the framework restriction that we cannot set the animation speed to 0 that is why the default value is 1. If you want faster Animation then just increase the AnimationSpeed to say 5 or something else whatever is your requirement, then you won't see the delay.
If you don't want any animation then just set AnimationType as None. Then you won't see any delay.

Hope this resolves your problem.

Please let me know if you have any other concerns.

Regards,
Padmaja
