The ASPxRadioButton control is a button that users can select, but cannot clear. When you use a set of radio buttons to allow users to select an input, they can select only one option.
<dx:ASPxRadioButton ID="radioButton" runat="server" Text="Send me notification emails" Checked="true" />
ASPxRadioButton offers the following features:
Native RenderingASPxRadioButton supports native rendering as a native HTML input element of the radio type. When native HTML mode is enabled, a control’s appearance depends on how a client browser renders native HTML elements. This reduces the render size and improves the editor’s overall performance. Set the Native property value to true to enable native rendering.Custom ImagesA radio button’s default edit region (the check mark area) contains an image and the ASPxRadioButton editor. You can assign your own images to display for different check states. Built-in ValidationASPxRadioButton allows you to validate data on both the client and server sides. See the following help topic to learn more: Validation.Full-Featured Client-Side APIThe ASPxClientRadioButton object is the client-side equivalent of the ASPxRadioButton control. This object exposes the control’s comprehensive client-side API.
