Designer error in vs2017

[Davy]

Hello, i get the following error in vs.

the error appears when i close the design mode form of the form with a palletegroupbar

Everything worked fine, but suddenly i got this error ...

PalleteGroupBar thrown an unhandled exception in the designer

(Can't attach to top level or parentless control)

[Davy]

I'm debuging and found the following.

The error only happens when the palletegroupbar (3) is nested in a split container (2) and this container is also nested in a split container (1)

1. private Syncfusion.Windows.Forms.Tools.SplitContainerAdv splTopBottom;
2. private Syncfusion.Windows.Forms.Tools.SplitContainerAdv splMenuForms;
3. private Syncfusion.Windows.Forms.Diagram.Controls.PaletteGroupBar sideMenuBar

if i only use one split container there is no error!

if i change the SplitContainerAdv's by standart SplitContainer's there is no error

Hi Davy

Thank you for contacting Syncfusion Support.

We have checked the reported behavior with Palette GroupBar. We have already faced this type of DesignError with GroupBar and it has been fixed internally. Since the PalleteGroupBar has been inherited from GroupBar , the reported issue has also been fixed. We have also taken the video for the same which shows no designer error occurs on closing the designer page for both GroupBar and PaletteGroupBar from following location:

This issue has already been fixed in the version 15.3.0.33 and your product version details also 15.3.0.33. So can you please confirm us your Syncfusion Product version details, it would be helpful for us to provide you the solution at the earliest.

Regards,
