how to populate FileExplorer from List?

Hi,

I am retrieving file names and meta data from Web Service and have them in a C# List.

How can I set this list as source to populate them in FileExplorer?

Tried something like that with no success.

 List<Telerik.Web.UI.Widgets.FileItem> files = new List<Telerik.Web.UI.Widgets.FileItem>();
 files.Add(new Telerik.Web.UI.Widgets.FileItem(filetmp.Name, filetmp.Extension, filetmp.Length, filetmp.FullName, filetmp.FullName, filetmp.FullName, Telerik.Web.UI.Widgets.PathPermissions.Delete | Telerik.Web.UI.Widgets.PathPermissions.Read | Telerik.Web.UI.Widgets.PathPermissions.Upload));

FileExplorer1.Grid.Source = files;

thanks
