Hello
I am "homegrown" programmer in C.
I want to have ListView Controll with Radiobuttons in my small app (Windows Mobile). I did something like that (see sall part of code):

This is ListView Controll with Checkboxes and I used mechanism which is used in this example:
http://www.codeguru.com/cpp/controls/listview/checkboxes/article.php/c1023/I know taht there are some tips & tricks to "tune up" that technique to use/view Radiobuttons (not CheckBoxes), espetially two:
- use custom drawing to add radio button
- create images for checked/unchecked "radio buttons" and only change these images after mouse-click on the "radio button" area
Unfortunalty I do not know how code it. Maybe you know some steb by step example witch is placed on some website and I can't finde using Google
. Maybe this is very simple and a few simple lines of code do the trick.
Best regards, Grzegorz Dragan.
