Hide class properties in dll control

I know 3 ways to hide Properties from Controls :

1: You create them (all) as dummi-Properties and set it's Attribute like described by OG.

2: You build an own Designer-Class for your control (each). In this Designer-Class you have the ability to remove the Properties with (for example) overriding the method "PreFilterProperties" ...

3: You implement the "ICustomTypeDescriptor"-Interface and it's methods into your control (each). In the overriden methods "GetProperties" you call an own method which removes the unwanted Properties from the List.

For the Items 2 and/or 3 I could give you VB-Examples how to do. The VB-Code is not very complicated so you should (if interested) be able to convert it to C#.

There is no point to do that...

However, if you want to limit access to a control or a set of them, you should put your control inside a user control. This could be particullary useful for complex controls like a grid or a chart when you want to only expose some properties.

You will still see "classic" properties of the user control like it size but you won't see properties of the nested control. You then add some properties to the iser control to give access to internal control properties of the nested control.
