Hi,

I've developed a couple of Windows Forms controls. To extend their
flexibility, in run-time, I should be able to define/add new properties for
those controls.

I know that Reflection.Emit namespace is for that purpose. I have searched
for possible examples about this and only found the ones which create the
assembly, module and properties (As a whole) from scratch. But I want to add
new properties to an existing Class?

Does anybody have any example about this? I need examples such as how to
retrieve mehtodbuilder from an exsiting class, etc. to add new properties?

Thanks in advance,

Özden

You can create a new class inherited from the original class and add your
new properties.

Hi Ozden,
Check out this link:

http://msdn.microsoft.com/library/de...et04082003.asp

Shows the use of Extender Providers to add properties, etc. to
textboxes but could work with any control. Well written article and
the download shows the source code. I used it to develop my own text
validator using much of Mr. Hollis' ideas but changing the overall
behavior to suit my needs.

Hi,

Thank you both for taking time and trying to help me...

I know I can extend a class by deriving from it and add my properties and I
also know Extender Providers to add properties to controls. But both of
these solutions are again static, I mean I hardcode which properties will be
added to my standart control. My problem was creating properties on the fly,
this means when I instance an object in my applicaiton, I add properties
into it and it becomes a modified class.

Anyway, I could find the solution at here :

http://www.codeproject.com/cs/miscct...g_property.asp

I hope it will be usefull for anybody in a situation like me...

Thanks again,

Özden
