Hi Naiyin,
Thanks for using Syncfusion products.
You can achieve your requirement by using ToolBarItemInfoCollection property of ToolBarAdv . Each
ToolBar item’s ToolBarItemInfo contains IsChecked property, with this you can
identify the hidden items in ToolBarAdv.
Download the attched sample.
Please let us know in case of any queries.
Regards,
Victory
