Hi Vishal,

I believe the following live demo will be of help in solving this case: FileExplorer / Filter files and download. It shows a possible way to handle the OnClientFileOpen() event in order to download the selected file.

The full code of this example (including the code of Handler.ashx) is available in the folder, where RadControls are installed on your computer. In order to make a file directly downloadable, you will need to add an HTTP header of type "content-disposition" (see the Handler's WriteFile()).

Please, refer to the following w3.org article for more information regarding HTTP header fields: Header Field Definitions.
 
Additionally, you could take a look at the following code library and a live demo (if you haven't done it yet), which are representing the way to integrate RadFileExplorer with a database:

•  Connect RadFileExplorer or RadEditor to a SQL databse
•  Custom File Content Provider, using an SQL database
