I think the NodeMouseClick event of the TreeView may be used for this purpose, as shown below

VB

Sub Main
    Dim form1 As New Form()
    
    Dim treeView1 As New TreeView()
    treeView1.Nodes.Add("N1")
    treeView1.Nodes.Add("N2")
    treeView1.Nodes.Add("N3")
    treeView1.Nodes.Add("N4")
    AddHandler treeView1.NodeMouseClick, addressof treeView1_NodeClicked
    form1.Controls.Add(treeView1)
    
    form1.ShowDialog()
End Sub

public shared sub treeView1_NodeClicked(sender, args)
    MessageBox.Show("Node clicked")
End sub

Solution 2

VB

Private Sub tvPlants_NodeMouseClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles tvPlants.NodeMouseClick
       tvPlants.CollapseAll()
       tvPlants.ExpandAll()
   End Sub
