[DefaultBindableProperty("MyCustomProperty")]
public class MyCustomLabel : XRLabel {
    // The following line specifies the Property Grid category, 
    // where a custom property is located.
    [SRCategory(ReportStringId.CatAppearance)]
    // When BindableAttribute is applied, the property will appear
    // in the Data category, as well as in the custom category (if specified).
    [System.ComponentModel.Bindable(true)]
    public string MyCustomProperty { get; set; }
}

public class MyCustomPageHeaderBand : PageHeaderBand {

    // a property appears in the Misc category.
    public string MyCustomBandProperty { get; set; }
}
