	I working with mindfussion.diagramming diagram. i can increase /decrease width and height by using numeric button. code is here BGBounds = New Rect(spnTemplateLeft.Value, spnTemplateTop.Value,spnTemplateWidth.Value, spnTemplateHeight.Value) diagram.Bounds = BGBounds BGNode.Bounds = BGBounds It's working fine. But when increase/decrease left and top numeric button then canvas area(bounds) of diagram is not updated. I am using this code: BGBounds = New Rect(spnTemplateLeft.Value, spnTemplateTop.Value,spnTemplateWidth.Value, spnTemplateHeight.Value) BGNode.SetBounds(BGBounds, True) diagram.Bounds = BGBounds If set color to diagram background so colored canvas area also not working. Please help me. Thanks in advance

	Have you attached all nodes in your diagram to BGNode? In such case calling SetBounds(..., true) will move them together with that node, so you won't notice any difference when changing the diagram and BGNode's origin. Call SetBounds(..., false) to leave child nodes in place and you should see the background move. I hope that helps, Stoyan

	Or if you meant to extend the diagram to the left or top rather than just moving the origin of its coordinate system, you must add the offset subtracted from left/top to the rectangle's width/height. I hope that helps, Stoyan

	Hi Stoyo, I tried with that but I am not getting it properly. Can you please help me on this and if possible a small demo project will be helpful. Waiting for your reply. Here is the code that I implemented on Left/Top numeric up/down value changed event: Code TemplateWidth = spnTemplateWidth.Value BGBounds = New Rect(spnTemplateLeft.Value, spnTemplateTop.Value, TemplateWidth, TemplateHeight) diagram.Bounds = BGBounds BGNode.SetBounds(diagram.Bounds, True) Thanks in advance for your valuable time. Regards, Yogendra

	It should look like this if you need to extend to the left/top while right and bottom boundaries remain unchanged: Code dim dx, dy as float dx = diagram.Bounds.Left - spnTemplateLeft.Value dy = diagram.Bounds.Top - spnTemplateTop.Value BGBounds = New Rect(spnTemplateLeft.Value, spnTemplateTop.Value, _ diagram.Bounds.Width + dx, diagram.Bounds.Height + dy) I hope that helps, Stoyan

	Thanks stoyan But if there are nodes on diagram so if i increase/decrease left/top then nodes should be moved, or diagram has some background in color then colored canvas area should be moved.

	And what would you expect to happen? Either move the nodes then, or maybe you should place your diagram inside a Silverlight Border element instead of drawing a border inside the diagram.
