Hi everybody.
I need to sort a treeview, but I must keep intact the child structure. Any idea about strategy
Example:
BEFORE SORT:
root
|
---parent2
| |---childX
| |---childA
|
---parent3
| |---childX
| |---childA
|
---parent1
|---childX
|---childA
AFTER SORT:
root
|
---parent1
| |---childX
| |---childA
|
---parent2
| |---childX
| |---childA
|
---parent3
|---childX
|---childA
Thank you very much for your help

Treeview parent sort
C#2.0
I just coded this up in Visual Studio 2005 and I have not tested it much but this seems to work (you need to add code to guard against nodes with the same text):
Dim sortedNodes As New SortedDictionary(Of String, TreeNode)
For Each node As TreeNode In Me.TreeView1.Nodes
sortedNodes.Add(node.Text, node)
Next
Me.TreeView1.Nodes.Clear()
For Each node As TreeNode In sortedNodes.Values
Me.TreeView1.Nodes.Add(node)
Next
TreeView has a Sort method if you provide a TreeViewNodeSorter (http://msdn2.microsoft.com/en-us/library/system.windows.forms.treeview.treeviewnodesorter) but this will sort all the nodes in the TreeView.
Best regards,
