How to check all ChildItems in a TreeView??

Hi!

I have a CheckedTreeView with an event "AfterCheck". So, always, when the Check-State of a button changes, the event is fired. In the event, I want to check or uncheck all child-Items of the selected Item.

So, I wrote a recursive method, that should work just fine. But the problem is, that I use the command "node.Checked = true" to check the childNodes. And always when the command is executed, the "AfterCheck"-event is executed.

Is there a way to suppress this event?

Or is there an easier way to check or uncheck all childItems in a treeView?

Thanks,
Barthi

Try this:

Private Sub TreeView1_AfterCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterCheck
Static itsMe As Boolean
If Not itsMe Then
itsMe = True
recurseNodes(e.Node, e.Node.Checked)
itsMe = False
End If
End Sub
Private Sub recurseNodes(ByVal nd As TreeNode, ByVal chk As Boolean)
For Each child As TreeNode In nd.Nodes
child.Checked = chk
recurseNodes(child, chk)
Next
End Sub
