    [CLOSED] msg.Alert() not working

    I have controller code:

    public ActionResult SaveGridDataChanges(StoreDataHandler handler, int gridID)
 {
            ChangeRecords<Object> rows = handler.BatchObjectData<Object>();
            
            try
           {
            ...
            }
}
catch (Exception e)
{
   X.Msg.Alert("Error:", e.Message).Show();
// X.Msg.Notify("Error:", e.Message).Show();
}
return this.Direct()
}
    not sure why is Notify() works but Alert() display no message ?
    Thanks

    The code you have posted appears to be correct.

    Please ensure you wrap all code samples in [CODE] tags.

    [Code] tag added to prev request. still not working. I switched to use global error handling as below. the onAjaxException() never been called. Could you help spot any API error? what is good way to debug this ?
    Thanks

@(Html.X().ResourceManager()
    //.ShowWarningOnAjaxFailure (false)
    .Listeners(l =>
          {
              l.AjaxRequestException.Handler = "onAjaxException";
          })
)

 <script>
 var onAjaxException = function (response, result, el, eventType, action, extraParams, o) {
            alert("Ajex exception called=" + eventType)
            if (eventType === 'event') {
                //ajax event already has its own error handler
                return;
            }

            Ext.Msg.alert('Error', result.errorMessage);

            // return false will stop event from bubbling
            return false;
        }
    </script>

  //direct event
        public ActionResult SaveGridDataChanges(StoreDataHandler handler, int gridID)
        {
            ChangeRecords<Object> rows = handler.BatchObjectData<Object>();
  
            try
            {          
             throw new Exception(" test error"); 
               
            }
            catch (Exception e)
            {
                //CPMAppUtil.LogError ("Error SaveCubeDataBulk gridid= " + gridID, e);
                ResourceManager.AjaxSuccess = false;
                ResourceManager.AjaxErrorMessage = "Data has no change";// not show
                throw e;
            }
          
            return this.Direct();
        }

    As for the original post.

    Both, X.Msg.Alert and X.Msg.Notify don't appear for me. It happens because a sync request doesn't executed a response JavaScript code automatically.

    As for global handling. Yes, it is possible, but it might be a bit problematic to extract an error message.

    I would recommend this approach.

    View
    @{
    var X = Html.X(); 
}

<!DOCTYPE html>
<html>
<head>
    <title>Ext.Net.MVC v2 Example</title>

    <script>
        var onStoreException = function (propxy, response, operation) {
            var message = operation.getError();

            Ext.net.Notification.show({
                iconCls: 'icon-exclamation',
                html: message,
                title: 'EXCEPTION',
                hideDelay: 5000,
            });
        };
    </script>
</head>
<body>
    @X.ResourceManager()

    @(X.Store()
        .ID("Store1")
        .Model(X.Model().Fields("test"))
        .Proxy(X.AjaxProxy()
            .API(action =>
            {
                action.Read = "GetData";
                action.Sync = "Sync";
            })
            .Reader(X.JsonReader().MessageProperty("message"))
        )
        .ShowWarningOnFailure(false)
        .Listeners(events =>
        {
            events.Exception.Fn = "onStoreException";
        })
    )

    @X.Button().Text("Sync").Handler("App.Store1.getAt(0).set('test','new value'); App.Store1.sync({});")
</body>
</html>
    Controller
    public ActionResult Index()
{
    return View();
}

public ActionResult GetData()
{
    return this.Store(new object[] 
    { 
        new 
        { 
            test = "Hello" 
        } 
    });
}

public ActionResult Sync(StoreDataHandler handler)
{
    try
    {
        throw new Exception("Some Error");
    }
    catch(Exception e)
    {
        return this.Store(e.Message);
    }

    return this.Store(new object[] {});
}
