Hi,

I need to implement following requirement:

We need to select a group of nodes and if they are of same type (say they have a property type as custom information added to the node) then we will show them in a composite group node which will show the group node images. If they are not of the same type then the grouping operation should be canceled displaying message "can not group, items are not of same type". The group can also be ungroup and restored to the previous state.

The intention behind this is that when we have lots of nodes in the tree so to display them on a single map they become too small (zoomtofit). So the idea here is to group them and display only group nodes, so that the group nodes can be seen more clearly.

How can we achieve above requirement with wpf diagram.

Thanks,

Thanks for the reply. But we want this feature to be available for not connected nodes also.

Actually we would like the user to select the nodes using a draw box to group them and then the operation as explained above should continue.

Thanks,
