Setting the BrowsableAttribute at Runtime

Nathan Sokalski

7/25/2009 10:26:00 PM

I have a class that I am writing in which I want to set the
BrowsableAttribute of a Property inherited from it's base class at runtime.
How and where would I do this? Thanks.

If you're building the type at runtime, you need to call
PropertyBuilder.SetCustomAttribute with a CustomAttributeBuilder you've
created with the Attribute you want.

Otherwise you can't change a compiled type at runtime.

You may however be able to use ComponentModel.TypeDescriptionProvider to
fake what you want, depending upon where you need the functionality.
Don't have time to explain this further now...

That sounds pretty simple, but I also need to know which eventhandler to do
it in (Init? PreRender? Load?). Thank you for the help.
