Private Sub CommandBarDropDownList1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles CommandBarDropDownList1.KeyDown
        If e.KeyCode = Keys.Enter Then
            MsgBox("hello", MsgBoxStyle.OkOnly)

Hello ricric,

Do you have the DropDownStyle set to DropDown?
If so, then you'd need to add the event handler to the TextBoxItem which will work for you. Please consider the following code

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    Me.CommandBarDropDownList1.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDown
    AddHandler Me.CommandBarDropDownList1.DropDownListElement.TextBox.TextBoxItem.KeyDown, AddressOf CommandBarDropDownList1_KeyDown
End Sub
Private Sub CommandBarDropDownList1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs)
    If e.KeyCode = Keys.Enter Then
        MsgBox("hello", MsgBoxStyle.OkOnly)
    End If
End Sub

If you have further questions, or a different requirement, please let me know
