                    dataType: "json",
                    data: {
                        models: kendo.stringify(options.data.models)
                    },
                    success: function (result) {
                        options.success(result);
                    }
                });
            },
        },
        schema: {
            data: 'data',
            model: {
                id: "imageUrl"
            }
        },
        change: function (e) {
            var view = dataSourceGetImageUrl.view()[0].imageUrl;
            $("#imageEditor").kendoImageEditor({


                imageUrl: view,
                width: "100%",
                height: 650,
                saveAs: {
                    fileName: "image_edited.png"
                }
            });

            var imageEditor = $("#imageEditor").getKendoImageEditor();
            imageEditor.one("imageRendered", function () {
                imageEditor.executeCommand({ command: "ZoomImageEditorCommand", options: imageEditor.getZoomLevel() - 0.2 });
            });
        }
    });

How to "new kendo.data.DataSource" can use "autoBind: false". And can call .read()

Hi Admin and everybody,

I am working with dataSource for Image Editor.

I completed get data and give it for Kendo Image Editor.

But, I cannot use it with "autoBind: false" to stop load when start page like Title or call it with .read().

This is my code:

var dataSourceGetImageUrl = new kendo.data.DataSource({
        transport: {
            read: function (options) {
                $.ajax({
                    url: "/_layouts/15/xxx/API/ApiHandler.ashx?tbl=like&func=getimageurl",
                    type: 'GET',
                    cache: false,
                    scriptCharset: "utf8",
                    dataType: "json",
                    data: {
                        models: kendo.stringify(options.data.models)
                    },
                    success: function (result) {
                        options.success(result);
                    }
                });
            },
        },
        schema: {
            data: 'data',
            model: {
                id: "imageUrl"
            }
        }
    });

    dataSourceGetImageUrl.fetch(function () {
        var dataSource = dataSourceGetImageUrl;
        var view = dataSourceGetImageUrl.view()[0].imageUrl;
        $("#imageEditor").kendoImageEditor({
            autoBind: false,     //It not working.It still read when my page start

            dataSource: dataSource,
            imageUrl: view,
            width: "100%",
            height: 650,
            saveAs: {
                fileName: "image_edited.png"
            }
        });

        var imageEditor = $("#imageEditor").getKendoImageEditor();
        imageEditor.one("imageRendered", function () {
            imageEditor.executeCommand({ command: "ZoomImageEditorCommand", options: imageEditor.getZoomLevel() - 0.2 });
        });
    });

I tried call .read() with code. But it not working

$("#imageEditor").data("kendoImageEditor").dataSource.read();

//OR

dataSourceGetImageUrl.read(); // All both not working. I cannot call .read() to reload

dataSourceGetImageUrl

Hope to get help soon from everyone. Thanks
