  Hello,

  Angular 5
  
  Typescript
  
  wijmo 5.20173.405

  I have next situation. Please go to Black Sabbat and choose Lady Evil, after that click edit names - here we have a problem that TreeView has collapsed.

  Now we try to select the node, that we have selected before edit action, please click “Select Node” - nothing …

  Can you please explain how to use TreeView control and get described behavior?

  I have made a plunker example.
  
  I know that I have the new reference to action “Edit”, but this is new service.

  Hi,

  On clicking the edit names button,the tree view is losing selection because you are changing its source(not recommended).

  However if there is requirement to change the item source and retain selection you can refer this updated fiddle.

  Hello,

  Waiting has paid off. Thank you very much, Sir. You made my day.

  I have one more question for you. How to recognize the difference if I have for example the item “Lady Evil” 3 times in the list. For example: Please go to Black Sabbat /Heaven and Hell and choose the second Lady Evil. Click on edit, the first Lady Evil will be selected - it should be the second one.

  Here is the plunker: http://plnkr.co/edit/SKCrp8AWQmKFxOifczCN?p=preview

  Thank You

  Hi,

  I think the best way would be to add a unique identifier to the DataSource for each item like an ID, so that we can know the exact node being selected and then re-select it based on the ID.

  If you need a sample let me know, I will try to give it you on Monday
