Say I have a DataGrid on one form, and a number of simple controls on
another form, both bound to the same DataSet. The form with the
DataGrid is launched from the control form, and the DataSet and the
name of the table are passed to the form's constructor and then
assigned to the DataGrid's DataSource and DataMember properties,
respectively.

1) What is the best strategy for keeping the two forms synchronized
(i.e. changing the focused row on the DataGrid updates the
CurrencyManager on the control form and updating the CurrencyManager
on the control form updates the focused row on the DataGrid)?

Now suppose the DataGrid is sorted by clicking on a column.

2) Is the sort applied to just the grid, or is the sort applied to the
assigned DataSource as well?

3) Once the grid is sorted, how do I keep it synchronized with the
control form?

Thanks....
