    [CLOSED] ResourceManager MessageBusListeners

    I would like to know whether you could add MessageBusListeners to the ResourceManager. I have a scenario, which i would like to add a MessageBusListener to the document as a whole and in my opinion, this listener would be clearer if it was added to the ResourceManager instead of another element of the page, such a Panel.


    Thanks in advance

    Hi Raphael,

    Yes, unfortunately, ResourceManager doesn't have MessageBusListeners.

    For listening to global events, we can recommend this C# code:
    MessageBus.Default.Subscribe("**", new JFunction("alert('I catch any event!');"));
    You could call it in a Page_Load, for example.

    Here is a JavaScript counter part:
    Ext.net.Bus.subscribe("**",function(){ alert('I catch any event!'); });
    You could run it in a ResourceManager's DocumentReady or in your own Ext.onReady() call.

    Thank you Daniil.

    Please mark this thread as closed.

    I would like to provide a simple sample:

    <!DOCTYPE html>
<html>
<head id="Head1" runat="server">
    <script type="text/javascript">
        var RaiseEvents = function () {
            Ext.net.Bus.publish("Event1", "Ext.Net");

            Ext.net.Bus.publish("Event2", "Sencha");
        }

        var DocumentReady = function () {

            //Subscribe to Event1
            Ext.net.Bus.subscribe("Event1", function (name, param) {
                alert(Ext.String.format("Event1 (Specific). Data received: {0}", param));
            });

            //Subscribe to all events
            Ext.net.Bus.subscribe("**", function (name, param) {
                alert(Ext.String.format("{0}. Data received: {1}", name, param));
            });
        }
    </script>
</head>
<body>
    <ext:ResourceManager runat="server" ScriptMode="Debug">
        <Listeners>
            <DocumentReady Handler="DocumentReady();" />
        </Listeners>
    </ext:ResourceManager>
    <br />
    <ext:Button Text="Raise Events" runat="server">
        <Listeners>
            <Click Handler="RaiseEvents();" />
        </Listeners>
    </ext:Button>
    <br />
</body>
</html>
