resizeToFitItems not updating node location? (Read 2906 times)

	I have just started using Diagram.ResizeToFitItems but it doesn't seem like the diagram.nodes shapenode bounds/center are being updated when I do so. Am I missing something? Dean

	This resizes the diagram object so it gets just big enough to contain all items. If you need to resize items to fit their contents, call ResizeToFitText or ResizeToFitImage from a loop. I hope that helps, Stoyan

	Thanks, Stoyo but what is happening to me is that the diagram resizes, the nodes move but the node locations don't change/update.

	Stoyo, I don't think I understand the relationship between the DiagramView.Size and the Diagram.Bounds. I see that the diagramView.Size is unchanged by the resizetoFit, the diagram is reduced as necessary and the diagram's x and y value are translated. The real problem I have is I am recording the location of the nodes on the diagramview so that when I redraw the diagram from scratch I can place them. I'm not sure how to integrate the resizeToFit behavior into this system. Should I record the diagram bounds, the on restore i would set the canvas size, place the diagram, and then plot the nodes relative to the diagram bounds? Thanks, Dean

	The nodes do not move, but the origin of the coordinate system shifts - that is the top-left corner of the diagram - so the nodes appear at a different position. If you want to update just the size of the diagram, you could save the Bounds value, call ResizeToFitItems(), and set Bounds to RectangleF.FromLTRB(oldBounds.Left, oldBounds.Top, newBounds.Right, newBounds.Bottom). I hope that helps, Stoyan

	how can one control the origin of the coordinate system programmatically? Thanks!

	You specify where the origin point is located inside the diagram by setting Bounds. Calling ResizeToFitItems changes Bounds too, so to restore the CS origin, you set the Bounds' Left and Top properties back to their old values. That should take care of all items being displaced on screen after calling ResizeToFit. I hope that helps, Stoyan
