I have a TreeView control in my WinForms .NET application that has multiple levels of childnodes that have childnodes with more childnodes, with no defined depth. When a user selects any parent node (not necessarily at the root level), how can I get a list of all the nodes beneith that parent node?
For example, I started off with this:
Dim nodes As List(Of String)
For Each childNodeLevel1 As TreeNode In parentNode.Nodes
For Each childNodeLevel2 As TreeNode In childNodeLevel1.Nodes
For Each childNodeLevel3 As TreeNode In childNodeLevel2.Nodes
Function GetChildren(parentNode as TreeNode) as List(Of String) Dim nodes as List(Of String) = New List(Of String) GetAllChildren(parentNode, nodes) return nodes End Function Sub GetAllChildren(parentNode as TreeNode, nodes as List(Of String)) For Each childNode as TreeNode in parentNode.Nodes nodes.Add(childNode.Text) GetAllChildren(childNode, nodes) Next End Sub
