I have a datatable that correctly populates from a SQL query, but I want to do a couple things with the datatable itself. First I want to only grab the rows that have a date of today or previous in the column "ECompletion", then I want to sort those by oldest date and finally push the results in order to lbl_urgentTasks.Text.

dtTasks = getDataTable("SELECT * FROM Tasks WHERE IsActive = 1");


Anyone know where I can start with this? I have searched online and didn't really find an answer. I have good experience with c# and the .net framework so don't be afraid to go crazy!
