Require Node at front

Hi Stoyo,

We have some overlapped nodes in our diagram.
Suppose node1 is partially behind the node2, now if I click on node1 it gets selected.
I want that it should select but it should also bring in front i.e. now node2 should behind the node1.

Note- I have tried with ZTop property and it was working as expected, but due to this we were facing many problems because at some places we are doing something with the ZIndex value. Is there any other way to achieve this?

Regards,
Anshul

Changing the ZIndex value is the only way to do that.

Hi Stoyan,

We have set node.ZTop() to bring it in front but at some places we are getting some problem.

Can we change zIndex of both nodes in selection change event so that we can set zTop for newer one and decrease zIndex for previous selected node?

How to get previous selected nodes?


Regards,
Anshul

Handle the NodeDeselected event to detect the previously selected node.

If you are using multiple selection and prefer to process all nodes together in a batch, you might save a copy of Selection.Nodes each time SelectionChanged is raised; before cloning it, loop over the already saved collection to find out which were the previously selected nodes.

I hope that helps,
Stoyan
