Hi,

Folded containers did not differentiate between child nodes and attached nodes and that lead to hiding the links. Please try that with this version:

I hope that helps,

  Hi,Stoyan.Your new version is useful.Now, all group would move when I am moving or draging the containers.
  I have another question to ask you.Suppose a container contains several tables.How can I layout all the containers automatically and
orderly after user triggerring the "ContainerFolded" or "ContainerUnfolded" event?
  My solution is rearrange all containers after "ContainerFolded" and "ContainerUnfolded" event.However,the result doesn't unsatisfactory.
triggerring the "ContainerFolded" or "ContainerUnfolded" event,the container would move to other corner of the screen,which is far away
from other containers.Yhe containers in the DEMO deal with it well.How can I solve it?
  Thanks a lot!

Hi,

The demo does not run any layout method when folding and unfolding containers. However all containers are expanded initially, and having that space reserved for them they do not overlap other nodes when folded and unfolded again.

If you are still using TreeLayout, try setting the TreeLayout.Root property to the parent of the container for which the event is raised. Then TreeLayot should rearrange just the tree branch that contains this container and it should remain close to its initial position.

Alternatively, save the difference between the container's position and [ScrollX,ScrollY], and after running the layout set [ScrollX,ScrollY] to the new position of the container minus the saved difference.

I hope that helps,
Stoyan
