Align to grid

Hi there,
Is it possible to set the alignment to grid of a node to it center. Now align to grid set the sides of every newly created or modified diagram item aligned to the nearest grid points. I want to align the center of the node to the nearest grid point.
It is possible to do this?

Regards,
Dexter

Hi,

You will have to disable the automatic AlignToGrid feature. In NodeCreated calculate the node center point, call diagram.AlignToGridPoint(center), and move the node with the same offset as the one between the original center and the aligned point.

I hope that helps,
Stoyan

It does not work. If I disable the AligToGrid then the method returns the same point and the offset will be 0. At create I solve the problem, but now at update bounds if I write the same code the movement will be from grid line i to grid line i+2 so no grid i+1. What I am doing wrong?

Best regards

Then in NodeCreated enable AlignToGrid temporarily before calling AlignPointToGrid.

I hope that helps,
