Short Name: Edit Tree Items.Delete

Requires: Base Development System

Class: TreeControl Methods

To Use: Create a method.

Deletes an item from the tree control. Wire an empty string to tag and a value of TRUE to Delete Children to delete all items in the tree control.

If you do not update the value of a tree control after deleting a row, the control may return old data. Deleting a selected item does not change the value of a tree control. After you delete an item, the tree value may be a tag for an item that no longer exists. You can select one of the remaining tree items to update the value of the tree control.

This method is similar to the Delete Item item on the shortcut menu of a tree control.
