Can you explain the Item2 part? I think I tried this one before by just calling Select and did not work.. Maybe i missed something. You are doing some smart thing for sure 👍

Haha, nothing smart here. InputNodes property on NodeModel is of type IDictionary<int, Tuple<int, NodeModel>>. I'm just getting the NodeModel part of the tuple.

If there is a chance, I would like to get some knowledge share around undo/redo recorder and what it means to reuse it. That is the only piece I am not sure if the way in this PR will be something we want to promote in the feature. |

@QilongTang I have done some final refactor - I have moved the commands from |

@aparajit-pratap Do you know if selection is part of undo/redo sequence? I have been thinking about if there could be any side effects to this but in general feels OK

This is not part of the undo/redo sequence. I think you'll need to use one of the selection related commands to add it to undo/redo queue.

Purpose
https://jira.autodesk.com/browse/DYN-2978
This builds on top of PR #11164.
The node chosen from node autocomplete suggestions is created, connected, and then placed relative to the initial node using the graph auto layout. A single undo-recorder group is initialized for this entire operation so that it can be undone in a single step. The following are the sequence of steps:
CreateAndConnectCommandto make it use an existing undo-redo recorder group instead of creating a new oneNodeViewReadyevent on DynamoViewModel is subscribed to. Only when this event is raised does the size of the new node created get set. Only once the size is set, can graph layout work correctly.NodeViewReadyevent handler the graph auto layout is performed using only the input nodes to the initial node. This is to ensure that the initial node does not jump to a new location on graph layout.Please hide whitespace to review this PR.
