Hi Admin and Everybody,

As the title, Currently I have read all data from the folder to the corresponding items of folder. But data children ( see picture 1.png ), can not reload when using ".read()".

When I using code call ".read". Only the area on the left hand side reloads, and the area on the right hand side doesn't happen.

More specifically, it's the children data area that doesn't reload when call ".read()"

$("#filemanager").data("kendoFileManager").dataSource.read(); // my code call .read()

My code will show all data to file manager:

$("#filemanager").kendoFileManager({
    dataSource: {
        transport: {
            read: function (options) {
                var that = this;

                $.ajax({
                    url: "my url",
                    dataType: "json",
                    method: "POST",
                    data: that.parameterMap ? that.parameterMap(options.data, "read") : options.data,
                    success: function (result) {
                        options.success(result);
                    }
                });
            },
            
        },
        schema: {
            data: 'data',
            model: {

               id: 'path',  

               children: 'items'  
            }
        }
    },
    toolbar: {
        items: [
            { name: "custom", type: "button", text: "Create", command: "MyCustomCommandCreate" },
            { name: "custom", type: "button", text: "Upload", command: "MyCustomCommandUpload" },
            { name: "sortDirection" },
            { name: "sortField" },
            { name: "changeView" },
            { name: "spacer" },
            { name: "details" },
            { name: "search" }
        ]
    },
    contextMenu: {
        items: [
            { name: "rename" },
            { name: "delete" },
            { name: "custom", text: "Detect", command: "MyCustomCommandDetect", spriteCssClass: "k-icon k-i-info" }
        ]
    },
    draggable: true,
    resizable: true
});

My json data has a structure similar to that of demo from docs Kendo ( https://docs.telerik.com/kendo-ui/api/javascript/ui/filemanager/configuration/datasource ) - EXAMPLE

Image show you my Json Data inside url link: ( 1.png )

Looking forward to hearing from Admin and everybody soon, thanks

Hi Stark,

As far as I understand, the data of the FileManager is initially loaded correctly, but after that, you need to reload the data in the FileManager. If this is the case I would suggest you use either the FileManager:

-  refresh() method that will refresh the current view of the FileManager and will rebind the data or

- the setDataSource() method

Here is a Dojo example of a FileManager that is reloaded using the setDataSource method. As you will see both the navigation side and right side containing the Grid/Listview of the FileManager are updated correctly.

Please try the suggestions from above and let me know about the result. In case the issue continues to persist, please send us an isolated runnable sample where the issue is replicated. This way I can debug locally and suggest a possible approach to resolving the issue.

Hi Stark,

The setDataSource method could not be used only for the items in the folders. If you need to replace only the items/folders/files you still need to use the setDataSource method and replace the entire dataSource. Here is an example.

I hope this helps.
