Event Handling for Controls within a Datagrid

[Wayne]

Hi!

Is there a way to trigger events for the controls within
the datagrid control? For instance, a check of a checkbox
that would toggle all the checkboxes in the datagrid; or a
dropdownlist on selectedindexchange would change the
content of a dropdownlist in the same datagrid row. I
notice there is no intellisense for those and I can't seem
to find anything within the help file.
