Checked Nodes in Treeview

[Ronald Rasmussen]

If I use the folowing code to walk through the checked nodes in a treeview will I ever get a child node BEFORE I get the parent node?

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)

For Each tv As TreeViewNode In TreeView1.SelectedNodes

Text1.Text += tv.Text

Next tv

End Sub

Hi Ron,

Thank you for your interest in Syncfusion products.

The child nodes can be retrieved before their parent node.

Following code snippet can be used to acheive your requirement

[C#]

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)
 Dim allCheckedNodes As New List(Of TreeViewNode)()
  childparent(TreeView1.Items, allCheckedNodes)
  For Each tv As TreeViewNode In allCheckedNodes
   Text1.Text += tv.Text
  Next tv
End Sub

Protected Sub childparent(ByVal listItems As IList, ByVal list As List(Of TreeViewNode))
 For Each tv As TreeViewNode In listItems
  If tv.HasSubNodes Then
    childparent(tv.Items, list)
  End If
  If tv.Checked AndAlso tv.ShowCheckBox Then
   list.Add(tv)
  End If
  Next tv
End Sub

Please let us know if it helps you.
