Hi together.

I am working on an application where we use the object ControlHost. In this we show our own Control, where the User can interact. Unfortunately we have some problems in using other features with ControlHosts.

1.) When the Control is shown inside the ControlHost now Anchor is shown.

2.) When we try to draw a link from one host to another it is nessecary, that the control host is a littlebit bigger than the control, so we can draw the link from a free place of the host. Trying to draw a link from inside the control is not possible. So the user has to "aim" exactly betwee control an border of host.

3.) Routing algorithm of Flowchart does not really works with the controlhosts. With normal Boxes there is no problem. The Link is drawn arround boxes. But when there is a Controlhost, the link is not drawn around controlhosts.

Are there any tipps or advices we can use to solve these problems?

For understanding here is the creation of an controlhost. it based on the example "photobook"

ItemControl record = new ItemControl();
ControlHost photo = flowChart1.CreateControlHost(10, 10, 54, 37);
photo.Control = record;
photo.Tag = "Main";
record.Chost = photo;
Group group = flowChart1.CreateGroup(photo);
group.Tag = photo;


photo.CtrlMouseAction = EHostMouseAction.hmaSelectHost;

photo.AnchorPattern = new AnchorPattern(


new AnchorPoint[]
{
new AnchorPoint(0, 0, true, true, EMarkStyle.msRect),
new AnchorPoint(0, 10, true, true, EMarkStyle.msRect),
new AnchorPoint(10, 10, true, true, EMarkStyle.msRect),
new AnchorPoint(10, 0, true, true, EMarkStyle.msRect)
});


thanks for all help

Hi,

1. There's nothing we can do about it. The controls are rendered in their own windows and hide the anchor points rendered in the flowchart's window. If you are now starting a new project, consider our WPF diagramming control - WPF allows for much better integration of custom controls in the diagram's visual tree.

2. Setting ControlMouseAction to IgnoreControl should let you do that, as long as the control does not capture the mouse input.

If you mean the selection handles, set the AdjustmentHandlesSize property (SelHandlesSize in older versions of the control).
