    [CLOSED] Prevent default action in radio group not working

    Hello, why is this not working? (the radio gets selected every time, it shouldn't)


    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!X.IsAjaxRequest)
        {
        }
    }

</script>

<!DOCTYPE html>

<html>
<head runat="server">
    <title></title>

    <script type="text/javascript">
        var change = function (item) {
            console.debug(item);
        };
    </script>

</head>
<body>
    <ext:ResourceManager runat="server" />

    <ext:RadioGroup runat="server" FieldLabel="Rating" ColumnsNumber="3" AutomaticGrouping="false">
        <Items>
            <ext:Radio runat="server" Name="rating" InputValue="0" BoxLabel="A" ReadOnly="false" />
            <ext:Radio runat="server" Name="rating" InputValue="1" BoxLabel="B" ReadOnly="false" />
            <ext:Radio runat="server" Name="rating" InputValue="2" BoxLabel="C" ReadOnly="false" />
        </Items>

        <Listeners>
            <Change Handler="change(item);" PreventDefault="False" StopEvent="True" StopPropagation="True"></Change>
        </Listeners>
    </ext:RadioGroup>
</body>
</html>

    Hi @exe,

    I think the Change event fires when a Radio's state is already changed and the event is not meant to be able to prevent it.

    As far as I can see there is no BeforeChange event in API.

    I can suggest this solution.
    <ext:Radio ...>
    <Listeners>
        <AfterRender Handler="this.onBoxClick = Ext.Function.createInterceptor(this.onBoxClick, beforeOnBoxClick);" />
    </Listeners>
</ext:Radio>
    var beforeOnBoxClick = function (e) {
    if (true) { // Prevent condition
        return false;
    }
};

    The workaround is working as expected.

    Thanks!
