Search TreeView

Question

Hi I've seen a number of people having this problem but no really good solution. I hope that anyone here got on. I have a TreeView that's populated with data from a DataView. Each row in the DataView contains an ID that's the primary key in the table. I have created a extended version of the TreeNode that contains a Key property where I store my ID. How can I search and find a specific node in my TreeView based on the ID? Do I really have to do a recurcive search of the whole structure? Thx Ante

TreeView does not have the ability to search. Also insted of creating specialised version of TreeNode you could have used TreeNode.Tag property to put custom data in there. But since you already have the custom TreeNode you could add search feature there: public MyTreeNode Search(string str) { if (db.Search(this.myCustomID str)) return this; else { foreach (MyTreeNode node in Nodes) return node.Search(str); return null; } }

Yes. I think you have to search it recursively. I dont think TreeView provides any method or property that allows you to search the contents.
