Insert an ASP.NET RadioButtonList control

1 Select Insert > ASP.NET Objects > asp:RadioButtonList.

2 In the asp:RadioButtonList dialog box, set the options as follows:

ID Specifies the name for the form control. The ID is required.

Tool Tip Specifies the text displayed when the mouse pointer hovers over the form control in a browser.

DataSet Specifies the data source you want to use to populate the items of the list control. If you don’t specify a

DataSet, you can specify one later or set the list items statically by clicking the List Items button in the Property

inspector.

Get Labels From specifies the field in the selected DataSet to provide the labels of the list items.

Get Values From specifies the field in the selected DataSet to provide the values of the list items.

Select Value Equal To specifies a value the server uses to determine which list item is selected when the RadioBut-

tonList is displayed in a browser. The server compares each item’s value to the specified value. If the values match,

the matching item is selected.

Access Key creates a keyboard shortcut that allows users to quickly navigate to the form control in a browser. For

single character.

Preselect an item in an ASP.NET RadioButtonList control

define a DataSet or other source of dynamic content for the radio buttons. Ideally, the source of content should contain

Boolean data, such as Yes/No or true/false.

1 In Design view, select the RadioButtonList control.
