TreeView and AfterCheck event

[TechnoTone]

I want to use the AfterCheck event on a TreeView to ensure all child nodes to the node that was checked/unchecked are the same. Unfortunately, the AfterCheck event doesn't tell you which node was checked/unchecked and the TreeView's selected node doesn't change either.

 

Any suggestions?

I've found 1 solution but it isn't ideal. It involves moving the selected node as the mouse moves over the control so that the selected node will alway match the clicked node.

 

If there is another way I'd be most interested in hearing of it.

 

 

 

  Private Sub TreeView1_AfterCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterCheck
     Static bIgnore As Boolean
     If bIgnore Then Exit Sub
     bIgnore = True
     CheckTree(TreeView1.SelectedNode)
     bIgnore = False
  End Sub

  Private Sub TreeView1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TreeView1.MouseMove
     TreeView1.SelectedNode = TreeView1.GetNodeAt(e.X, e.Y)
  End Sub

  Private Sub CheckTree(ByVal RootTreeNode As TreeNode)
     With RootTreeNode
        Dim subNode As TreeNode
        For Each subNode In .Nodes
           subNode.Checked = .Checked
           CheckTree(subNode)
        Next
     End With
  End Sub

The AfterCheck event _does_ tell you which node was checked :)

:eek: Thanks Divil. I could've sworn I checked the parameters and didn't find it. Oops!!

 

I'll get my coat.

 

 

 

I could still do with some advice on my other issue though.
