Controls You Can Use on Web Forms   ASP.NET Standard Controls   RadioButton and RadioButtonList Controls

When you use a RadioButtonList control, you add a single control to the page. Adding items to the control is a separate process that depends on whether you will display a static list in the control or a list generated dynamically at run time. For details, see Adding Items in a List Control.

NOTE: The procedure for working with individual RadioButton Web server controls is different. For details, see Adding Individual RadioButton Controls to a Web Forms Page.

1. Declare an <asp:RadioButtonList> element on the page. For syntax, see RadioButtonList Control Syntax.
2. Optionally set the RepeatDirection property to either Horizontal or Vertical ( default ).
3. Optionally change the orientation of the caption by setting the TextAlign property to either Left or Right ( default ).
