Saving non-image Files to database


I have a database with a table for proposals.
I managed to create a blazor server-side app where I can add/edit the proposal data using template forms and display the proposals list in a grid.

I was wondering if it is possible to have a control in the template forms to upload proposal documents (RAR file) to the database and show a download link in the grid.

what control should I use in template forms? and what do you recommend the corresponding database table column data type to be?
