If you would like to save only the name of the image in the database and keep its storage on the server disk, you can specify ImageUrl
for the binary image as explained here
or use regular asp Image control to achieve your goal. In case you perform editing operations in data bound control, you can embed the binary image or the standard asp Image in item template and MS TextBox inside edit template of a template column (the second would be to store the name of the image in the grid source).
Generally, the purpose of the RadBinaryImage control is to visualize an image streamed from byte array in the grid's data source.
