	I want to have functionality like this:- I want to avoid overlapping of Nodes(Boxes and ControlHosts) while dragging or Moving in Flow Chart .NET

	You could handle the BoxModified and ControlHostModified events and change the dropped node location if it overlaps another node. Use the Node.Intersects to determine whether two nodes intersect. It is up to you to choose where to place a node if it was dropped over another one.

	Thanks stoyo. I thought about this solution but I want some good interface. while dragging node itself user should recognise that on this place he can not drop perticular node.

	Hi, You might change the mouse cursor icon from the *Modifying event handlers to show that a node cannot be dropped at a particular location. Just set the FlowChart.Cursor property. Stoyan
