DiagramView DrawShape

I'm testing with the trial version of Windows Forms.

If the Behavior property of DiagramView is set to DrawShape, when we draw small areas, seem that you have a minimum distance when drawing the node.
What property should I change for a more sensitive drawn?
And, what property should I change for nodes are transparent? (without any shading, to see the background image)

Thanks for advanced

Set smaller Diagram.MinimumNodeSize value to allow drawing smaller nodes.

Set node.Brush to a SolidBrush(Color.Transparent) to remove the fill of individual nodes, or change Brush to null in the current theme's style if you need that for all nodes.

You might also want to remove shadows by setting Diagram.ShadowsStyle = None.

I hope that helps,
Stoyan

The problem is not draw small nodes.
diagramView.Diagram.MinimumNodeSize.Height = 0.0;
diagramView.Diagram.MinimumNodeSize.Width = 0.0;


The problem is in the redraw with the cursor or moving a node. It seems as exists defined minimum distance to draw or moving when distances are very short.
Is there any property to change that?

Is possible to move nodes with keys.Up, keys.Down, keys.Left, keys.Rigth??

Thanks

Set it to a small size, but not zero:
diagramView.Diagram.MinimumNodeSize = new SizeF(0.01f, 0.01f);

Zero size is the default, however the control enforces a MeasureUnit-independent one millimeter size when at default value.

See http://mindfusion.eu/Forum/YaBB.pl?num=1323665629/1#1 for moving with arrow keys.

I hope that helps,
Stoyan

MinimumNodeSize doesn't solve the problem.
The property to which I referred is diagram.AlignToGrid = false.

Thanks for everything

Right, I forgot about that. You might also make the alignment grid smaller by setting the GridSizeX and GridSizeY properties.

I hope that helps,
