Custom paging in FileManager control

[Dishant]

Hello to all,

I am stuck in a problem where files are loading at a time and the FileManager control is taking some time to load so is there any other way like "Lazy Loading" or "Custom Pagination" that I can do to improve loading speed?

Thank you.

Hello Dishant,

Could you please let me know if you are loading multiple items in the FileManager? If this is the case, you could use the default load-on-demand behavior of the FileManager. You could move the hierarchy logic entirely to the server. To do that you should implement a Read endpoint for the FileManager DataSource that would return the appropriate items for a given level and folder. For example, when initially loading the FileManager and its root directory, the service would return only top-level items. When a user opens a folder, the FileManager will automatically send a request to the remote containing information (the path) about the folder that is being opened. Then the service should return all items that are directly placed within that folder.

Here is an example of such a read endpoint implemented in our Demos service:

The above is used in our Demos examples:

If it is suitable for your scenario, you could configure serverPaging for the FileManager DataSource. You could take a look at this article, where information on how this paging should be implemented is provided:

I hope this helps.
