My grid panel gets its data from a table in Oracle. One of the columns in that table has blob data (file). I want to allow the user to click on a link from the grid that opens up the file. Similarly I want to let the user upload a file from the UI and save it to the database. Is there a way to handle the file upload/download using extjs. I am using version 3.4. Will greatly appreciate if you can explain with some examples. Thanks.
