    [CLOSED] Interceptor for checkbox check event

    Hi,

    On checkbox, while the user clicks on Checkbox, we have to show a confirmation message. If user accepts, we need to go ahead check the checkbox. Otherwise, we should not check the checkbox.

    Is there a way to intercept the check event of Checkbox?

    Hi,

    I can suggest the following solution.

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

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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Ext.NET Example</title>

    <script type="text/javascript">
        var setValueSilent = function (checkbox, checked) {
            checkbox.suspendEvents();
            checkbox.setValue(checked);
            checkbox.resumeEvents();    
        };

        var onCheck = function (checkbox, checked) {
            setValueSilent(checkbox, !checked);
            Ext.Msg.confirm('Confirm', 'Confirm?', function (btn) {
                if (btn === 'yes') {
                    setValueSilent(checkbox, checked);
                }
            });
            Ext.Msg.getDialog().alignTo(Ext.EventObject.getTarget());
        };
    </script>
</head>
<body>
    <form runat="server">
        <ext:ResourceManager runat="server" />
        <ext:Checkbox runat="server">
            <Listeners>
                <Check Fn="onCheck" />
            </Listeners>
        </ext:Checkbox>
    </form>
</body>
</html>
