Hyper Link column type is a special definition allowing you to call event/function. Just like,
displaying this container for example.
You can use this column type to update the picture ID inside this grid, upload,
download, start a video/audio clip, open a new window, request a report, etc.
Of course, all in relation with the current cell/row/grid being selected.
Please refer to the file JsGridHyperLink.js for more explanation.
