<RadioButton>

Syntax Remarks Example

The RadioButton tag renders as a radio button and associated label at run-time. Using a series of RadioButton controls, along with the GroupName property, you can create a list of mutually exclusive options. This can be a useful alternative to using a RadioButtonList. With the RadioButtonList, only one value is sent to the datasource. If you use RadioButton controls that are grouped, you get the same mutually-exclusive options, but you also have the ability to store the value of each RadioButton in its own data field.

Remarks

AccessKey: In browsers that support it, this property can be set to a character on the keyboard that can be used to set focus to the control. For instance, setting the value to F allows the user to access the control by pressing Alt+F on their keyboard (for Windows machines)
BackColor: Color of the background of the control.
BorderColor: Color of the border around the control
BorderStyle: Style of the border around the control.
BorderWidth: Width of the border around the control, specified in units
Checked: Determines whether the radio button is checked.
CssClass: Name of the Cascading Style Sheets (CSS) class used to style this control
DataField: Name of the parameter in the <submitcommand> which will be filled with this control's data on when the form is submitted and/or the parameter in the <selectcommand> which will supply this control's data when the form is loaded. This attribute is required if the control will participate in operations with your form's data commands.
