    in SP1 we found a new property ToolTipText.
    This works when used at runtime.

    To reproduce.
    Build a WinApp.
    Drag a RadPanelbar to it.
    At some Elements.
    Take the first RadPanelBarGroupElement and enter some text under Properties/ToolTipText

    Close the form (in VS) and open it again.

    I get the following error messsage:


    Error setting property "ToolTipText" in class "Telerik.WinControls.RadItem" to value "TestTT".

    The error was:
    System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.

       bei System.ComponentModel.ReflectPropertyDescriptor.SetValue(Object component, Object value)

       bei Telerik.WinControls.Design.RadObjectCustomPropertyDescriptor.SetValue(Object component, Object value)

    Hi Manfred,

    I confirm the issue and it will be fixed as soon as possible. It is already added to our bug tracking system as it was reported by you a day ago. The workaround is to set the ToolTipText property through the API of the control, not through design-time. We will have this property fixed for the next release.

    Sincerely yours,
