If no selected nodes in TreeView control

Hi...
When I refere to selected Node in TreeView control, when no selected nodes are, error occurs.. How can I check, is there any selected Node in my TreeView control?
Thank you very much.

Hello there...

Well, here is a way to find out if you have any selected nodes in your tree.

For i = 1 To TreeView1.Nodes.Count

If TreeView1.Nodes.Item(i).Selected = True Then

...hold the i somewhere and you have the selected node...

End If

Next


Hope it helped

Ok, thanks a lot...
But probably there must be an easiest way? Probably using some standart method, or comparing like
if TreeControl.Nodes.SelectedItem = Nothing ..... ?????

I think that was the easiest way to find out if you have selected nodes in Treeview.

There is an easier way, browsing for each nodes in a treeview can be a pain if you have a lot of nodes (like it is often the case with treeview), try that code:

Code:

---

Private Sub Command1_Click()
    Dim objNode As Node
   
    'Get the selected node
    Set objNode = Me.TreeView1.SelectedItem
   
    'Remove the selection to test
    Set objNode = Nothing
   
    'Test if selection
    If objNode Is Nothing Then
        MsgBox "No selection"
    Else
        MsgBox "Selection: " & objNode.Text
    End If
   
End Sub

---

Remove that line afterward :)
Set objNode = Nothing

NO Me.TreeView1.SelectedItem in Visual Studio 2010.

is there any other way?

This is the VB6 forum, and VS2010 is supported in the .Net forum...
