Greetings from Syncfusion support.
We checked your reported query and suspect your requirement is to define the files in some data source property. The File Manager structure is based on a client-server architecture and the operations are processed by using ajax requests sent to the server. So, it is not possible to do local binding on the client side.
However, you can use your own files and data in the File Manager by launching the local File Manager service and placing your required files in the path specified in the controller part of the service. Please find the local File Manager service below
Once this service is launched refer its URL in ajaxSettings
URL property of the File Manager.
We have prepared a sample for your reference by using local web service and files. Please find it below,
Note: Run the File Manager local web service first and then open the above sample.
Since each operation is processed using ajax requests, you can also modify the response data in the controller part of the File Manager local service based on your requirement. The response sent for operations must be in the format mentioned in the below document,
Let us know if you have any concerns.
