ZIndex questions

Hi there,

During creation of diagram items the zindex of it is not set. In the event diagram_nodeCreated the zindex of the node given in the event args has the zindex set to 0. In the node modified event the zindex value changes. I am not using containers or attached nodes. There are simple shapes nodes and table nodes.

Can you please help?

Regards,
Dexter

Hi,

If you are trying to set ZIndex of all nodes to 0, that won't work. The ZIndex of diagram items corresponds to their position in the Diagram.Items collection. Once an item is added to the diagram,  it's ZIndex is kept to a unique value in the range 0..n-1, where n is the number of items. If in NodeCreated you set ZIndex to 0, this will shift the ZIndex of all other items.

I do not set any ZIndex values. So, to understand better, at creating a new diagram item and adding it to the collection of items the insert is actually at index 0? Because this is what I am seeing. Is this correct?

Nope, I'm seeing consecutive integers printed with this code while drawing nodes:

private void diagram_NodeCreated(object sender, NodeEventArgs e)
{
     Debug.WriteLine(e.Node.ZIndex);
}
