I wonder if there is a easy possibility to show downloadable files as a clickable link, to directly download a file instead of right click -> open.
Probably an additional column with a link or a download image would also be a possibility.
You can use the solution provided in the following live demo: Filter files and download. To download the file just double click on it.
Another approach is to attach to the OnClientItemSelected client event of RadFileExplorer to download the file on a single click as shown in the attached project.
