jQuery FileManager - Custom
Use the custom provider's methods to handle file operations (add, delete, rename, and so on).
The following code shows how to create a custom file system provider and bind the FileManager UI component to it:
jQuery
$(function () {
$("#file-manager").dxFileManager({
fileSystemProvider: new DevExpress.fileManagement.CustomFileSystemProvider({
getItems: function(pathInfo) {
// Your code goes here
},
renameItem: function(item, name) {
// Your code goes here
},
createDirectory: function(parentDir, name) {
// Your code goes here
},
deleteItem: function(item) {
// Your code goes here
},
// ...
})
});
});Angular
