ControlsEx : index of the node

[nicolasWhite]

Hello.
Is there any way to return the index of the selected node?
:BangHead:

The treeview knows it!

node1.Value = treeview.SelectedNode

I've tried many ways including this one.

ode.Value = tv.SelectedNode
Msgbox(node.Value)

The message box is empty.:sign0148:

You need this:

Sub tree1_AfterSelect
      node1.Value = tree1.SelectedNode
      Msgbox([B]node1[COLOR="Red"].Text[/COLOR][/B])
End Sub

Thank you for your help , but i'm talking about node's index not the text property
I've been mucking with it the whole day and now I'm thinking about something like
index = StrAt(node1.Text,3).Well... it's a drag.
It seems to me that it's impossible in Basic4ppc to get the index of the selected
node.

What exactly do you mean with "index of a node"? This is a tree structure, an index isn't really meaningful.

Maybe the TreeViewPlus library will help you - I added a Tag property to every node, so you can give an index of your preference to the node when the tree is built, and then use it.

I'm trying to do an app similar to Basic4ppc help file.When a node is selected
a form with a multiline textbox is shown.

Sub tv.AfterSelect
Node.Value = NodeN.index 'wish such expression was available
index = Node.Value
FormRecords.Show
TextBoxRecords.Text = Table1.Cell("content",index-1)
'Table1 is in the *.lit file.

I think I can find a way to do it without getting a node's index.
Best Regards.

I had a similar problem with my ToDoTree application.
My workaround was to "misuse" the selectedImageIndex, storing a value that I need to save and load the data for this node.

E.g.:

node1.value = tree1.AddNewNode("something")
node1.selectedImageIndex = 'rowOfTable for this node'
...
...
...
node2.value = tree1.selectedNode
rowOfTableForSelectedNode = node2.selectedImageIndex

Maybe tis solution works for you (if you don't need separate imgages for your nodes).

storing a value that I need to save and load the data for this node.

This is what I'm working on now Still I'm having a strong temptation to resort to
combobox.
