I would like to simplify/structure data input in my datagrids by adding a databound datetimepicker (filled with data from another table) into my datagrids.

I have seen a retail product that allows putting comboboxes, images, and other controls into a datagrid column. I am using Enterprise Visual Studio .NET. Are there any freeware versions of this add-in? I know that over time I could learn to build this, but I am in a time crunch...and a money crunch. Any info would be awesome! Thanks!
