Hi, I would like to display checkbox in my treeview only on lowest level...For e.g. Let say that my hierarchy has 5 levels... I would like to display checkbox only on 5th level...
Is it possibble, and if yes I would appreciate a lot your help in order to make it works for me...

Note: the hierarchy depth can be different from hierarchy to hierarchy (it can be 5, 6 7 etc level hierarchy)

I do´n like use API.

I control when user can check each Node CheckBox on TreeView.BeforeCheck

Private Sub TV_BeforeCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewCancelEventArgs) Handles TV.BeforeCheck
       Select Case e.Action
          Case TreeViewAction.ByKeyboard, TreeViewAction.ByMouse
          Case Else : Return
       End Select

       Dim f = TryCast(e.Node.Tag, Fcs2)
       If f Is Nothing Then Beep() : e.Cancel = True : Return
       If f.IsIndicador Then
           If MessageBox.Show("¿ Desea eliminar el indicador ?", "Eliminar Indicador", MessageBoxButtons.YesNo) = Windows.Forms.DialogResult.No Then
              e.Cancel = True : Return
           End If
       Else
           Dim nd = e.Node.Parent
           Do Until nd Is Nothing
              If nd.Checked Then Beep() : e.Cancel = True : Return
              nd = nd.Parent
           Loop
           If TieneIndicador(f) Then e.Cancel = True : Beep() : Return
       End If

       Dirty = True
       mSave.Visible = True
    End Sub

Open in new window
