Vista - get child node of selected parent node

All,

I've tried working on this this before with no luck. I've looked all over
and can't seem to find a sample that I can redo (understand) to test with my
sample.
I've created a treeview with nodes from the sample below. I'd like to be
able to use the TreeView1_AfterSelect to retrieve the child node text values
and tag values.
to place in message box or userform labels.

If I select parent node Visual-Runway-A in the treeview I'd like to collect
the text values and tag values for all nodes(0)...under the parent
Visual-Runway-A. )
Pretty new to dot net.

Thanks for all your help.
John



TreeView1.Nodes.Add("Visual-Runway-A")
TreeView1.Nodes(0).Tag = ("Visual-Runway-A")
TreeView1.Nodes(0).Nodes.Add("Inner Width").Tag = "250"
TreeView1.Nodes(0).Nodes.Add("Outer Width").Tag = "1250"
TreeView1.Nodes(0).Nodes.Add("Surface Length").Tag = "5000"
TreeView1.Nodes(0).Nodes.Add("Slope").Tag = "20:1"
TreeView1.Nodes(0).Nodes.Add("Radius").Tag = "5000"

TreeView1.Nodes.Add("Visual-Runway-B")
TreeView1.Nodes(1).Tag = ("Visual-Runway-B")
TreeView1.Nodes(1).Nodes.Add("Inner Width").Tag = "500"
TreeView1.Nodes(1).Nodes.Add("Outer Width").Tag = "1500"
TreeView1.Nodes(1).Nodes.Add("Surface Length").Tag = "5000"
TreeView1.Nodes(1).Nodes.Add("Slope").Tag = "20:1"
TreeView1.Nodes(1).Nodes.Add("Radius").Tag = "5000"

continues.......to nodes(5) not shown

Private Sub TreeView1_AfterSelect _
(ByVal sender As Object, _
ByVal e As System.Windows.Forms.TreeViewEventArgs) _
Handles TreeView1.AfterSelect

Dim tn As TreeNode = e.Node
Dim d As New Dictionary(Of String, Object)

For Each child As TreeNode In tn.Nodes
d.Add(child.Text, child.Tag)
Next

' do something with the dictionary
End Sub

e.Node contains the node selected, and the Nodes property contains the
children of that node.

Mike,

Thank you, I was able to add your sample and retrieved the child.text and
child.tag under the selected parent.
would I have to do another for each loop to to get the remaining child text
and tags under the parent.

in this sample if I select the parent node Visual-Runway-A
I'd like to get all child text and tag so I can read them into a messagebox

any hints or links are welcome.

have a great day
John

TreeView1.Nodes(0).Nodes.Add("Surface Length").Tag = "5000"
TreeView1.Nodes(0).Nodes.Add("Slope").Tag = "20:1"
TreeView1.Nodes(0).Nodes.Add("Radius").Tag = "5000"

TreeView1.Nodes.Add("Visual-Runway-B")
TreeView1.Nodes(1).Tag = ("Visual-Runway-B")
TreeView1.Nodes(1).Nodes.Add("Inner Width").Tag = "500"
TreeView1.Nodes(1).Nodes.Add("Outer Width").Tag = "1500"

The keys should have been "Inner Width", "Outer Width", "Surface
Length", "Slope" and "Radius". The values for the keys respectively,
should have been "250", "1250", "5000", "20:1" and "5000".

Are you not getting this from the code when you select "Visual-Runaway-A"?

Mike,

Sorry, I now see the dictionary in the locals window under d and it is
cycling thru
the items under the selected parent node. I've never worked with a
dictionary or treeview before, I was looking in the wrong location.

In debug I can see the d.item keys and vlaue string as it iterates thru and
populates the dictionary, but when I try to get the values I don't see how to
get the d.tem key and d.item value string as shown in the locals window.

I know this is a struggle working with someone who doesn't understand these
newer control items but in time I will learn how these tools work, the old me
would of just made and if Visual-Runway-A was selected then form label
1,2,3... are equal to what I already types in the tree text, I'm trying to
change that.

Have a great day,
John
