Forces the Tree List to finish its initialization.
You must call the ForceInitialize method before changing a TreeList's options when a form is being loaded. After the Tree List has been initialized, you can manipulate its settings safely. For instance, you should call the ForceInitialize method before:
- applying data sorting;
- changing summary settings;
- expanding and collapsing nodes;
- creating columns and changing their visible state;
- restoring a layout, etc.
