问题 I can't find any list of the available attributes for the PropertyGrid in C#, do you know where I can find one? Thanks. 回答1: The attributes that impact PropertyGrid are indirect: the interesting code is the TypeDescriptor which provides the PropertyDescriptor implementation.

问题 I'm using a WinForms property grid to display the properties of an object. However, most of the properties are read only and thus show up as grey rather then black.

But I'm not sure exactly how I can access ControlPaint.DrawStringDisabled . 回答1: Unfortunately, there's no built-in way to change the

问题 I have ProperyGrid loaded with categorised PropertySpec and set to CategorizedAlphabetical sort. When form runs categories then items within categories are sorted. An annoying artefact is that PropertyGrid by default selects the first item after list was sorted and sometimes it scrolls view to selection.

问题 I have a property on my World class that looks like this: public Vec2 Gravity { get { Console.WriteLine("Getting gravity!"); return GetGravity(); } set { Console.WriteLine("Setting gravity!"); SetGravity(value); } } The "Getting gravity!" string is displayed as expected, when the PropertyGrid tries to read the value, but when I try to change the gravity vector and press enter, nothing happens. Why not? My Vec2 class has properties: public float X { get { return x; } set { x = value; } }
