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, you can specify one later or set the list items statically by clicking the List Items button in the Property
inspector.
Get Labels From

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

example, if you enter K, the user can navigate to the control by typing Alt+K. The access key can only consist of a
single character.
Auto Postback

selection. Select the option to allow postbacks.
For more information on ASP.NET RadioButtonList properties, see the documentation on the Microsoft website at

You can let the server decide whether to select a radio button in a RadioButtonList control when the ASP.NET page
is loaded in a browser.
Note:
Before you begin, you must insert at least one ASP.NET RadioButtonList control in your page. You must also
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.
2
In the Property inspector, click List Items.
3
Select the From Database option, and set any of the following options:
