How to handle errors

[Iwhp]

How can I handle errors, which for example occur on the server side.
I have defined this HierarchicalDataSource:

    var childrenDataSource = new kendo.data.HierarchicalDataSource({
        transport: {
            read: {
                url: function (options) {
                    return kendo.format("../api/hierarchytree/{0}", options.id);
                }
            }
        },
        schema: {
            model: {
                hasChildren: "hasChildren",
                id: "id"
            }
        }
    })

Hello Harry,

Use the dataSource error event.

All the best,
