The "Cannot create property 'summary' on string 'success'" error occurs when the infinite scrolling is used and the grid gets its data source from an AJAX request

created 7 years ago (modified 7 years ago)

[DevExpress Support Team: CLONED FROM T600250: DataGrid - Pages not loading on Android in AngularJS]
Hi Gosha,

Thanks for the explanation. You were right about the angular controller. I didn't attach the created datasource as controller to the angular module "DemoApp".

I've tried your sample, but the same error persists. I can see you can't access my JSOn web service because of the Cross Origin restrictions. I've included a dump of the result as a json file and set the datasource's URL to this .json file. The same error is keep poppuing up.

"Cannot assign property "summary" on "success" in dx.all

It works just fine in Internet Explorer 11, but doesn't seem to work in Chrome and FireFox.

I've attached the sample which doesn't rely on the web service.

Many thanks in advance,

    Thank you for your code. I've managed to reproduce the issue with it. I can also reproduce this issue with the Ajax Request demo if I enable infinite scrolling. See the CodePen sample. We will research this issue. Watch for our updates in this thread. At the moment, set the CustomStore loadMode option to "raw":

    JavaScript
    var dataSource = {  
    store: new DevExpress.data.CustomStore({  
        load: function () {  
            return $.getJSON("./T600250.json");  
        },  
        loadMode: "raw"  
    })  
}
