Hello:

In a TreeView:
In the AfterSelect even. How I can get the Index of Child node?

-Germany
--Bonn
--Berlin
-Italy
--Roma
--Pissa
--Napoles
-France
--Paris
--Lion

When the user selects "Pissa" How I can get the Index and subindex of "Pissa"?

thanks

Each node has one index which is related to its parent.
You can use IsRoot to check if this node parent is the TreeView or another node.
Then call TreeView.IndexOfNode or get the parent node and call Node.IndexOfNode.

thanks for your reply. But still not working well.

Sub Globals
'Declare the global variables here.
End Sub

Sub App_Start
Form1.Show
CreateTree
End Sub

Sub CreateTree
Tv.New1("Form1",10,10,100,150)
Node1.New1
Node2.New1
Node3.New1
Tv.AddNewNode("Germany")
Tv.AddNewNode("Italy")
Tv.AddNewNode("France")
Node1.Value=Tv.GetNode(0)
Node1.AddNewNode("Bonn")
Node1.AddNewNode("Berlin")
Node1.Value=Tv.GetNode(1)
Node1.AddNewNode("Roma")
Node1.AddNewNode("Pissa")
Node1.Value=Tv.GetNode(2)
Node1.AddNewNode("Paris")
Node1.AddNewNode("Lion")
End Sub

Sub Tv_AfterSelect
'TextTree IndTree TextNod and IndNode are TextBox
TextTree.Text=Tv.SelectedText
IndTree.Text=Tv.IndexOfNode(Tv.SelectedNode)
Node1.Value=Tv.SelectedNode
TextNod.Text=Node1.Text
IndNode.Text=Node1.IndexOfNode(Node1.Value)
End Sub

I want IndTree is the Index of the parent and the child index is IndNod. But both are the same. Can you help me? Thanks

Add another node Node2:

B4X:

Node1.Value = Tv.SelectedNode
If Node1.IsRoot Then
 msgbox(Tv.IndexOfNode(Node1.Value))
Else
 Node2.Value = Node1.Parent
 msgbox(Node2.IndexOfNode(Node1.Value))
End If
