What is the exact type of "TextBox" or "ComboBox"? There is a number of different controls under these names. Full names, please. And you always need to tag UI library you use.

And please don't forget to ask a question.

Your controls are part of the Controls collection of the form, but if you're creating them dynamiclaly, you're better off putting them in a collection so you have kept a reference to them and can refer to them from there. You can set their id in code, and look for it, or use a dictionary to map a value ( probably a string ) to each control you want to look for.
