DataBound Controls and DataTable

Hi All, got a couple noob data binding questions.

Say I have a DataTable bound to a datagrid. Do changes made to the data in the datagrid only modify the data in my data table object, not the database?

If this is the case. Is there a way to track what records in the data table have been modified, added or deleted since the data table was first created and bound to the datagrid?

thnx.

One way is assigning your old datatable to a new datatable that has only changes . Like this :

Code:

---

//YourDataTable = a datatable that has data you are working on .
DataTable NewDT=new DataTable ();
NewDT=YourDataTable.GetChanges();

---

Exactly what I was looking for I think. thanks.
