Hi Mat,

The default is to only grow the container size when nodes are placed near its edge, but never to make it smaller. In addition, the container will never become smaller than its MinimumSize value. Add this to the initialization code and the container should conform to your Margin value:

container.AutoShrink = true;
container.MinimumSize = new SizeF(10, 10);

I hope that helps,

Hi,

The container's code looks like this:

if (result.Width < minimumSize.Width)
     result.Width = minimumSize.Width;
if (result.Height < minimumSize.Height)
     result.Height = minimumSize.Height;

if (autoShrink)
     return result;
else
     return Rect.Union(result, GetBounds());

"result" contains the bounding rectangle of all child nodes. It seems your problem happens because of setting the container rectangle to the union of the old container rectangle and "result". I don't know if that's correct - our developer will check it. You can still avoid getting strange-looking results by setting smaller MinimumSize for the container, so that the statements in the "if" blocks are not executed. Everything seems to work fine if you add this to the initialization code, and the position set by the user is preserved too:

container.MinimumSize = shape.Bounds.Size;

I hope that helps.

Hi,

This version should work fine even without changing the MinimumSize:
