foreach (var node in form.Nodes)
{
var adapter = node as DiagramNodeAdapter;

if (adapter != null && adapter.Control is ContainerNode)
{
if (adapter.Selected == true)
{
ContainerNode c = (ContainerNode)adapter.Control;
c.Stroke = mycolor;
c.CaptionBackBrush = mycolor;
}
}
}


This code work correclty for all my nodes, but not for containers.

Are you sure your containers are inside adapters? Try this instead:

Code
Select All
foreach (var node in form.Nodes)
{
    var container = node as ContainerNode;
    if (container != null && container.Selected)
    {
        container.Stroke = mycolor;
        container.CaptionBackBrush = mycolor;
    }
    // ... handle adapters next
}


I hope that helps,
Stoyan

Why containers nor are inside DiagramNodeAdapter?

var adapter = node as DiagramNodeAdapter;

DiagramNodeAdapter is used to host custom controls that do not derive from DiagramNode. You could probably host a container inside DiagramNodeAdapter too, but then some features might not work, such as adding children to the container interactively or folding it.
