Groups within Groups

Hi,

We are using Diagramming control version 5.3.5 and trying to implement Groups within groups. I have a default group for the nodes of the diagram and I have to have groups within groups. Here I am finding issue selecting the inner group when added to existing default group of the workflow diagram.

I think the ZIndex is causing the issue as I am unable to select the node within an inner group box in the UI, it is always selecting the group box when I click on the node of inner group.

Please suggest a solution for this.

Regards
Velidanda

Does that inner node have higher ZIndex than the group node? I think attached nodes are drawn above parent nodes by default, but hit-testing is always done according to the ZIndex values.

Inner nodes have lesser ZIndex than Group node.

ZIndex of nodes attached to Group doesn't seem to have higher ZIndex though they are getting attached to Group node.

Do we need to explicitly set the ZIndex for the nodes which should be higher than Group node?

Yes, you'll have to set it explicitly.

Thanks, got the zindex set during attaching the nodes to group but somehow it is getting changed when selecting the nodes within the group and playing with it and sometimes the group node getting unselectable.

Is there any chance that the zindex gets reset to some different value based on any other events that makes it unselectable?

An item's ZIndex might change when setting ZIndex of another item, are you doing that in response to any selection events? ZIndex is actually the position of an item within the diagram.Items collection, whose elements' positions might shift with +/- 1 to adjust for the changed position of another element.
