How to detect changes in a DataGrid control

Question

I simply want to know if any data has changed in a datagrid control. My first thought was to use an event such as DataGrid.Change. There doesn't seem to be any such event or property that I can use to determine if I need to do an update. More background... I'm using a form with a single control, a DataGrid. The DataGrid is bound to a DataView which is created at runtime when the form is created. The DataView comes from a DataTable/DataAdapter. I can have multiple "views" of the same rows of data because each view is attached to its own form. I need to know if any of the data of any row/column in a datagrid has been changed so that I can force an update or at least prompt the user to update when necessary. Why is there no obvious event or property for this?

Also if you have many controls bound to same data then .NET updates all controls when one control does a change to the central datasource.

Why don't you bind to a DataSet if you want to use the DatGrid to modify rows? Then you can use a DataAdapter to update database using DataRow RowState property. RowState states whether DataRow was changed/added/deleted.
