Is it possible to search for a treenode within in tree by the treenode text? I have a windows form application C# application that allows users to create new tree nodes and assign ID as text. I need to make sure the ID value they assign is unique within the parent.
- Category 1 (ID = 001)
- SubCat 1 (ID = 031)
- SubCat 2 (ID = 091)
- SubCat 3 (ID = ----> If the user trys to enter 091, 031 or 001 for the ID, then I need to display an error. How can I search within a tree?
- Category 2 (ID = 004)
