Hi Brian,
Thank you for your interest in Syncfusion Products.
CategoriesToIgnoreInCusDialog property is used when you don’t want to display certain categories in the Customization Dialog.
//This method adds the Category that is to be ignored based on the Index specified.
this.mainFrameBarManager1.CategoriesToIgnoreInCustDialog.AddRange(new int[] { 1 });
//This method removes the Category that is already ignored based on the Index specified.
this.mainFrameBarManager1.CategoriesToIgnoreInCustDialog.RemoveRange(0, 1);
Please refer the sample available in the following link that illustrates the usage of this.
