UserControl的类别，CustomControl属性

Question

I'm developer my new CustomControl , I know when I put [Caterogy("MyCategeory")] on the property, it will create a new category in the property List in design mode

Example:

[Category("Mask")]
public string Mask
{
    get
    {
        return _Mask;
    }
    set
    {
        this._Mask = value;
    }
}

What name is this? How to I can search about it? I want meet others features for customize my control property, but I don't know how to called it and I don't know what more can I do for customize my properties

Example, how to can I set a property contains get, set, but no show in the property list?
