Overview - RadioButton

RadioButton is a button control that can be selected, but not cleared, by an end-user. While paired with other radio buttons, RadioButton enables end-users to select a single option from a group of choices.

Implementation Details

RadioButton is realized by the RadioButtonExtension class. Its instance can be accessed via the ExtensionsFactory.RadioButton helper method, which is used to add a RadioButton extension to a view. This method's parameter provides access to the RadioButton settings implemented by the RadioButtonSettings class, allowing you to fully customize the extension.

RadioButton's client counterpart is represented by the ASPxClientRadioButton object.

Declaration

RadioButton can be added to a view in the following manner.

View code (ASPX):

<%
    Html.DevExpress().RadioButton(
        settings => {
            settings.Name = "RadioButton1";
            settings.Text = "Check me";
            settings.Checked = false;
            }
        )
        .Render();
%>    

View code (Razor):

@Html.DevExpress().RadioButton(
    settings => {
        settings.Name = "RadioButton1";
        settings.Text = "Check me";
        settings.Checked = false;
    }).GetHtml()
NOTE

The Partial View should contain only the extension's code.

The code result is demonstrated in the image below.
