Web Forms Server Controls   Controls You Can Use on Web Forms   ASP.NET Standard Controls

---

The RadioButton and RadioButtonList Web server controls allow users to select one item from a short, predefined list. The following topics provide information that you will find useful in learning to work with these two controls.

Because there are two different controls, and because they function somewhat differently, it’s important to understand their different purposes. You can refer to the following table to determine which topics pertain specifically to the control you want to work with.

NOTE: Some of the topics listed below for the RadioButtonList control do not pertain solely to that control; instead, they are topics that apply to all list Web server controls ( ListBox, DropDownList, CheckBoxList, and RadioButtonList ) .
