Layers

How hard would it be to add layers to the flowchart control? For example, to show the user the print boundaries of the page, display the layout guides, etc.
The reason I am asking is that there is a need have an element that always appears behind all other objects on the diagram.

It should not be hard, but isn't that something like the Z order ? E.g. you can have an element in the background by setting its ZIndex to 0 and locking it so users cannot select and modify it, kind of what the first sample in the FCDemo does.

Yes, Z-order certainly helps. But..lets say I have a filled box with Z-order set to 0. If selected, the box "pops-up" and completely overlaps whatever objects above it in z-order. Right now to work around this I have to set the FillColor to "Transparent" and turn the shadow off.

Setting flowchart.SelectionOnTop = false should help in that situation - the background box won't pop up even when selected.

... but then layers might come handy if you need some boxes to come to front when selected and others to stay in the background when selected.

Wouldn't this setting affect the entire diagram? I just want to prevent background boxes from popping up... It would have been helpful if  there was a property to configure a specific object from popping up.
