Handle NodeClicked:

BUG:

c.Foldable = false;

When i save the diagram, and open again, container appear with that circle with arrow for fold and unfold.
That not should be happen.

Thank you so much, this work perfect.
Just found few problems and limitations make container less suefull in some situations:

c.TextAlignment = TextAlignment.Center;

The text no is correctly cenetered, is a little moved to the left when use center and use foldabe false.

The other problem i see, happen when container is folded and then resize unfolded.
By example:

I unfold container, then resize, then locate some objects inside, then fold.
If i resize now the container when is folded objects inside not are showed and container not work how should be.
I think resize container when is folded no have any sense and any practical use so is ok, but i need prevent this happen, i need prevent resize when container is folded.
How can prevent container be resizable when is folded?
I just want drag and move when is folded, but no want resize enabled when is folded.
Some sugestion?
Can add this like feature please?

Fnally the other problem i see is a lack of feature make the container right now less usefull under some situations.
When open container close to the bottom of diagram, the container go outisde of the diagram.
Really be good if this can be improved or fixed.
By example if container is located at botom position, when is unfolded should be unfolded in in upward direction, in that way contianrs can be used on anyportion of the screen.
With current behaviour only can be used on top, or in the middle of screen or something like that.

Can implement please some behaviour for make container can open in any oposite direction when is near to bottom borders?
I mean open in oposite direction if contaner unfolded not fit im portion of the screen available.
A simple and probably the best workaround for this, is rotate the container, but when i rotate more prolmes come.
By example if I rotate 180 degres, the text appear inverted, the fold and unfold (captionsection) remain on top of the container, and contaner continue unfold out of screen. ; (
I think rotate contianer will be the best option, if container automatically continue working when is rotated. This feature add a great fucntionality to container and fix the limitation I explain aboout container go out of scree when is unfolded near to bottom, lef or righ or the sreen.


Aditional to this problem i found a possible bugs:

Create container in same way I create:

ContainerNode c = form.Factory.CreateContainerNode(100,100,100,100);
c.Bounds = new Rect(e.MousePosition, new Size(100, 100));
c.Folded = false;
c.Foldable = false;
c.AutoShrink = false;
c.Text = "Test";
c.TextAlignment = TextAlignment.Center;
c.CaptionBrush = Brushes.White;
c.CaptionHeight = 25;
c.Stroke = Brushes.Red;
c.Brush = Brushes.Black;
c.StrokeThickness = 3;
c.CaptionBackBrush = Brushes.Red;
c.FontSize = 14;
c.Constraints.MinWidth = 100;
c.Constraints.MinHeight = 100;
c.FontFamily = new FontFamily("Arial");
c.HandlesStyle = HandlesStyle.Custom;
c.TextVerticalAlignment = AlignmentY.Center;
c.MinimumSize = new Size(100, 100);
c.Selected = true;



For fold and unfold i use this method:

private void OnNodeClicked(object sender, NodeEventArgs e)
{
     var ctr = e.Node as ContainerNode;
     if (ctr != null &&
           e.MousePosition.Y < ctr.Bounds.Top + ctr.CaptionHeight)
           ctr.Folded = !ctr.Folded;
}


Now, create a container, then fold, then copy and paste.
When unfold the copyed container, contianer just is resized to very little size.

Letme know if can reproduce this possible bug, this bug only happen when container is empty


If container have some object inside, when copy and paste when is folded, the border disappear!
Also, size is wrong, position of object incorrect.

Please check.


Best regards.

I understand the concept of not work with resize and use by example with AutoShrink.

The problem with autoshrink is really work bad for 2 reasons.

The object draged inside the diagram, touch the border od container and autotrink always catch the object an resize not leaving any marging.

If by example AutoShrink have configurable marging in pixels:
example
AutoShrinkMargin = 10;

That be ultra usefull.
I know this is only cosmetic thing but cosmetic is always important in a software.
Can please add this feature?

The second problem with AutoShrink is when you drag object, close to border of container, is very easy, object go out of container, object should be go out only when object is 100% out of container.
Right now that not happen and is very easy move object out of container by accident or error.
Can be this fixed?



About this comment:
If a container is near the diagram bottom boundary, you can either enlarge the diagram or move the container upwards from the ContainerUnfolded event handler.
Please can show a code example?
Best regards.

1. Ups! sorry i not see container marging before, no idea why, probably for not read more lol.
Is great, now margin is fixed and work perfect!!

2. Really sorry but no is how work here, inmediate after i put out of container more of 25% of object, object go out of container, i cna create a video for you if you want see this.
Im testing with custom UserControl. (nodes are UserControl)
Can be related?

3 Thank you for the example i test soon.


I need check why my diagram objects go out of teh container when i justdrag a little more of 25% of object.

If you are using DiagramNodeAdapters to show user controls, perhaps your user control size doesn't match the node's Bounds size. Check the SizeSyncMode property for a couple of options you have. Also make sure you don't use fixed-size elements in your control templates, and apply dynamic layouts using grid or stack panels instead of placing child elements at fixed positions.

I hope that helps,

You will have to make your BlackShape control adapt to the node size. Check if some of the panels used inside it doesn't have fixed Width and Height. If there's such panel, remove the Width/Height setters so that it fills whatever size the parent control has.
