Solution 1

FindNode[^] accepts valuePath[^] as a parameter with specific PathSeparator[^]. Seems, you pass wrong value.

The TreeView1 is empty, by this code i have filled treeview from active directory , but i cannot search from tree view..

DirectoryEntry directoryObject = createDirectoryEntry();

//Searcher.Filter = ("(objectClass=organizationalUnit)");
foreach (DirectoryEntry firstChild in directoryObject.Children)
{
if (firstChild.Name.Contains("OU"))
{
TreeNode Node = new TreeNode(firstChild.Name.Remove(0, 3));
TreeView1.Nodes.Add(Node);
}

}
