How do you get the collection of rows that have been added to the TreeListView? Currently our usage of the TreeListView is to display data elements that we have converted from an older version to a newer version. Many of the elements in the TreeListView may have errors or warnings associated with the translation. Sometimes we want to see these elements displayed in the TreeListView, and sometimes we only want to see the successful ones, and sometimes we want to extract these errors and warnings and put them in a list control, so extraction is needed. Thank you for any recommendations that you have.
