I am new to programming learning about VB.NET.

I have a treeview which I added nodes in the TreeNode Editor. I would like to show the "child nodes" in Listview when I click on a node in treeview (like windows explorer). I saw many tutorials but I do not understand them. What is the EASIEST way to do this?

hi jantrey, you could use the AfterSelect event to step through the Nodes collection of the selected node:

Private Sub TreeView1_AfterSelect(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterSelect
        Me.ListView1.Items.Clear()
        Dim oNode As TreeNode

        For Each oNode In TreeView1.SelectedNode.Nodes
            Me.ListView1.Items.Add(oNode.Text)
        Next
End Sub

well the better way to do that is dragging an ImageList control from the toolbar to the Form, then select the new added imagelist control and in the property windows fill its Images property which is a collection of images, once you have done so, select the ListView control and in the property windows set its SmallImageList and LargeImageList properties to the ImageList control added in the previous step (also you can have two ImageList control, one for each property). Then you can modify the event handler:

Private Sub TreeView1_AfterSelect(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterSelect
        Dim theItem As ListViewItem
        Dim oNode As TreeNode

        For Each oNode In TreeView1.SelectedNode.Nodes

            theItem = New ListViewItem(oNode.Text)
            theItem.ImageIndex = 0 'HERE setting the first image
            Me.ListView1.Items.Add(theItem)
        Next
End Sub

Jantrey,

If you are going to develop this further, I suspect that eventually you will need a method of getting the system-default icon for each item.
