HI I want to remove all nodes and connections in a diagram surface, but i cannot find a method to accomplish this work. Could anyone tell me how to do this? Thanks Best |

I have try the following code: ds.Diagram.Nodes.Clear() ds.Diagram.Connections.Clear() however, the diagram surface never notices that the connections/nodes are removed and still draws them. Any suggestions? |

Hello, Sorry about this. I'd suggest iterating the nodes and connections and call RemoveAt to remove them one by one. If you need to do this in multiple places, you could implement this in a single place that you can reuse. Here is a possible implementation: The main reason we don't handler Clear() in the product is because the collection changed event handler does not provide the original items before they were cleared, and so we can't iterate the old items to remove the visuals. I've made a note to improve this in a future version. -Jason Fauchelle |
