I know how to select some rows from a grid as indicated here: http://agiletoolkit.org/blog/how-to-select-elements-in-a-grid/
But I want to do the opposite, I want to have a grid, with selectable column, where I want to have checked the rows with certain ids from database, and then be able to unselect some or select a new one.
Is there a "prefered" method to do that in Agile Toolkit?
