How to select all the leaf nodes of the parent node?

Platform: WinForms |
Control: TreeViewAdv |
Published Date: April 30, 2011 |
Last Revised Date: July 10, 2014


We can select all the leaf nodes of the parent node by just selecting the parent node by handling the AfterSelect Event handler.


private void treeViewAdv1_AfterSelect(object sender, System.EventArgs e)


TreeNodeAdvCollection tn = new TreeNodeAdvCollection();

foreach (TreeNodeAdv n in this.treeViewAdv1.SelectedNodes)


this.AddChildren(tn, n);


foreach (TreeNodeAdv n in tn)





private void AddChildren(TreeNodeAdvCollection tn, TreeNodeAdv n)


foreach (TreeNodeAdv child in n.Nodes)



this.AddChildren(tn, child);




Private Sub treeViewAdv1_AfterSelect(ByVal sender As Object, ByVal e As System.EventArgs)

Dim tn As TreeNodeAdvCollection = New TreeNodeAdvCollection()

For Each n As TreeNodeAdv In Me.treeViewAdv1.SelectedNodes

Me.AddChildren(tn, n)

Next n

For Each n As TreeNodeAdv In tn


Next n

End Sub

 Private Sub AddChildren(ByVal tn As TreeNodeAdvCollection, ByVal n As TreeNodeAdv)

For Each child As TreeNodeAdv In n.Nodes


Me.AddChildren(tn, child)

Next child

End Sub
