New user, delete data from server question

Hi all, so I am new to using DataTables and am currently working on a project which displays data from a MS SQL 08 server. Currently it displays it fine, sorts fine, but i need to add the ability to delete the data and i am confused as to where i would put the select/delete commands in the code. Ive searched around and havent been able to find anything that gives a rather clear example of how to do this (Though i could be blind and if someone has a link to an example of this that would be GREAT)

Thanks guys
