Hi Mahmoud,

In order to add custom columns to the grid of FileExplorer, you will need to extend a little the ResolveRootDirectoryAsTree() and ResolveDirectory() methods in your custom DB content provider.

You can see a live implementation of such scenario in the following live demo: Add custom columns.
Also there is useful information on the subject available in this help article: Adding custom columns in the RadFileExplorer's grid.

Kind regards,
