How to set Control Points?

Print Post  
For a diagramNode, if the node is not locked, when it is selected, the control points will show.
1. Usually it was 9 points (3 x 3), I want to get rid of the middle one. How to do that?
2. Is there any way NOT show the control points even it is not locked? when I put the diagram as not editable, the control points are still shown.

Thanks,

3. My coworker also wants to know is there any way to re-define the size of those white or gray control boxes? We want 8 or 4 white control points and each box is much smaller.

Set node.HandlesStyle = HandlesStyle.SquareHandles2;

You could clear the selection when entering read-only mode, or assign transparent brushes to properties of ActiveItemHandlesStyle and SelectedItemHandlesStyle. Alternatively, loop over nodes and set their HandlesStyle to Invisible.

Set diagram.AdjustmentHandlesSize /= 2;

I hope that helps,
