Bonnie,

Thank you very much for the sample code. Two more follow up questions, please (you are not getting rid of me easy <g>).
1. Do I understand correctly that you put the code (as in the example you kindly provided) in a .cs file of my project? Like, MyUIClasses.cs?
2. Do I then have to reference this namespace in the forms/classes where I will use them using the "using" syntax. That is, I would put the following in each class?

using MyCompany.WinUI.MyClasses

Again, thank you.

>That's it. These controls can't be sub-classed visually, but as you can see, it's easy enough to do it in code. I have all the basic controls sub-classed in one class library file. Once they're added to the ToolBox, then can be dragged onto any design surface in the IDE.

>>Ok, Bonnie, you asked for it <g>. Watch out, here comes a very newbie question <g>. Say, I have a web project, MyProject and I want to create my class library (I am using VFP terminology, so please forgive me) of commonly used controls (e.g dropdownlist, textbox) based on the .NET classes. What do I add to my project, a class? Or maybe you remember a thread or a link that explains how to do it?

>>>The cool thing is, Dmitry, is that you can start off with sub-classes with nothing in them and add the features you feel you'll need as you learn more. If you've already sub-classed your basic controls and used those sub-classed controls on your Forms already, then you'll have nothing to change when you start adding additional functionality to your sub-classes.
