Hello Iomega,

You can use this check in order to determine whether the RadFileExplorer control has items :
if (RadFileExplorer1.TreeView.IsEmpty &&
    (RadFileExplorer1.Grid.Items.Count == 0)
   )
{
    //"RadFileExplorer1 is empty";
}

I hope this helps.

All the best,

Thanks for reply.

In which event Can i Check this?  I want to check this in the next situations:

1) after page load
2) after delete a file

If you have a custom filtered(public class CustomProvider : FileSystemContentProvider), and in the directory exits 10 files, but just 1 file is inside your filter, and you delete that 1 file, if you checkRadFileExplorer1.Grid.Items.Count  its value is 9 instead of 0. So it returns your directory isn't empty.

Hi Iomega,

The best event where you can check the items in the grid (you can use the same event for the TreeView as well) is the ExplorerPolulated one. For your convenience I have attached a demo that shows the described approach.

I hope this helps. 

Sincerely yours,
