  First as a prologue, I am aware of the deficiency that radmenus do not show the accelerator key all the time, despite the windows default having been set. To get around that, I have added code which I have found elsewhere in this forum, basically this:
  
  

  Public Sub ShowMenuShortCuts(ByVal AMenuItems As Telerik.WinControls.RadItemOwnerCollection)

      Dim i As Int32 = 0

      While (i < AMenuItems.Count)

          Try

              CType(AMenuItems(i).Children(2).Children(0).Children(1).Children(0), Telerik.WinControls.Primitives.TextPrimitive).ShowKeyboardCues = True

              AddHandler CType(AMenuItems(i).Children(2).Children(0).Children(1).Children(0), Telerik.WinControls.Primitives.TextPrimitive).PropertyChanged, AddressOf MenuPropertyChanged

   

              If (TypeOf AMenuItems(i) Is myMenuItem) AndAlso (CType(AMenuItems(i), myMenuItem).Items.Count > 0) Then

                  ShowMenuShortCuts(CType(AMenuItems(i), myMenuItem).Items)

              End If

          Catch

              'Failure

          End Try

          i += 1

      End While

  End Sub

   

  Public Sub MenuPropertyChanged(ByVal sender As Object, ByVal e As PropertyChangedEventArgs)

      Dim tPrimitive As Telerik.WinControls.Primitives.TextPrimitive

      tPrimitive = CType(sender, Telerik.WinControls.Primitives.TextPrimitive)

   

      If (e.PropertyName = "ShowKeyboardCues" AndAlso (Not tPrimitive.ShowKeyboardCues)) Then

          tPrimitive.ShowKeyboardCues = True

      End If

  End Sub

  
  
  I am pointing this out because it may be relevant to current issue.
  
  Ok let's say you have this in place:
  - You have parent window, with a menu, where one of the items has an accelerator key of "a".
  - You have a child window, with a control, with an accelerator key of "a"
  So two controls with the same accelerator key. Here is what you do with normal windows forms to invoke one or the other
  - If you HOLD DOWN the Alt key, and press your accelerator letter at the same time, this invokes the control on the child window.
  - If you press and RELEASE the Alt key, the focus is now on the menu, and you can then type "a" to invoke the menu item.
  
  But here is what happens if the menu is a radmenu:
  - I press and HOLD DOWN the Alt key, and then press "a" at the same time. Result? Focus goes to the menu. It should not, it should set focus to the control on the child form.
  
  Thanks for looking.

  Hello Blair,

  Thank you for reporting this issue.
  
  I can confirm that the focus goes to the menu - we will consider changing this behavior.
  In regards to the mnemonics, the Alt key is needed only when the focus is not on the control where you need to apply the mnemonic. After this control gets the focus, you can select an item only by pressing the mnemonic key, the Alt key is not needed anymore. If you want to change the selected item only when the Alt key is pressed, you should use the RadShortcuts approach.
  
  We have added points to your account for the suggestions. Do not hesitate to contact us if you have other questions.

  Greetings,
  Peter
