I want be able to delete a datagrid row AND rows out of a data grid if a checkbox is checked. The checkbox is part of the row (the first cell). Right now I cannot detect if the checkbox is selected or not after it has been sent to the datagrid. I would like to check which rows are checked and then remove all of the rows that have a selected check box (call removeTaskRecord()). How can I do this? I just started learning Flex, so all suggestions with accompanied code are appreciated. Thanks
