Hi,

if I set ToolTipText in RadPanelBarGroupElement it works.
This means if I run the program it shows up the tooltip.
This is new (a fix I would say) in Q3 SP1.

But when I 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)
---------------------------
OK  
---------------------------

Regards

Manfred

Hi Manfred Pohler,

I confirm this issue. It will be addressed as soon as possible.

As a workaround, I suggest setting the ToolTips through the API of RadPanelBar by getting the instance of
the captionElement using the GetCaptionElement method and setting its ToolTipText and AutoToolTip properties.

Please write me back if you have additional questions.

Kind regards,

Hi,

setting the ToolTip via code like you suggested already worked before SP1.
The difference (I see for SP1), that (at runtime) I can directly use ToolTipText as porperty and don't have to mess around with ".GetCaptionElement" and such things.

But I would say the new property is buggy!

Hi,

You're right Manfred. We've had an issue with this property and we've already fixed it. The fix would be present in the next release of RadControls for WinForms. We greatly appreciate your valuable feedback.

Your points have been updated!
