Flowcharts on Flowcharts.

Hey Stoya

I have a controlhost with a flowchart as its control.  The flowchart always appears in front of other nodes on the base flowchart regardless of the z-order.  Is there away to include one flowchart in the z-order of another... if that makes any sense.  Any help you can offer is appreciated.

Cheers.

Hi Joshua,

There is no way to do that, because each flowchart is rendered in its own window. You could still implement something similar using grouping and the NodeConstraints.KeepInsideParent property.

Would this be the same situation as with any control embedded within a ControlHost?  I assumed that you could never make a chart object (a box for instance) appear on top of a ControlHost.  Are you saying that this is possible using grouping and the NodeConstraints.KeepInsideParent property?

I would very much like to know more about implementing this.  I haven't been able to find a KeepInsideParent property in the NodeConstraints class.

Thanks,
Jason

Sorry, I meant that he could avoid using flowcharts in ControlHost nodes, and instead use grouping to create container-like boxes.

We have added KeepInsideParent recently, probably in version 4.2; it prevents users from moving subordinate nodes out of their parent node.

Ahh, I see.  Then am I correct in my assumption that a Box can never appear on top of a ControlHost?

Thanks,
Jason

If there is any way to create a bitmap from the contents of controls that you use in ControlHosts, you might create such bitmaps and display them inside boxes. Then you could create a ControlHost only when users need to edit the node data. E.g. handle the BoxClicked event, display the hosted control at the same location when the event fires, and delete the control when the user completes editing the data.

yes, a box cannot appear on top of a ControlHost.
