An event that does not appear in the Property Grid

Question

I am creating a special search text box. Among other things, these are two events:

    [Category("Behavior")]
    public event EventHandler<GenericEventArgs<string>> Search;

    [Category("Property Changed")]
    public event EventHandler<EventArgs> ActiveColorChanged;

    [Category("Property Changed")]
    public event EventHandler<EventArgs> InactiveColorChanged;

The fact is that only two bottoms appear in the event constructor of constructor properties (whatever that is ...). And I wonder why. Is it because I do not use the standard EventArgs? This should not be so, because I mean that there are other events that do not use this ... like events related to a keystroke, etc.

The class is GenericEventArgs<T>as follows:

public class GenericEventArgs<T> : EventArgs
{
    public T Value { get; private set; }
    public GenericEventArgs() : this(default(T)) { }
    public GenericEventArgs(T value) { Value = value; }
}

What am I doing wrong here?
