How to get modified rows from a datagrid , when the changes are made on the editable datagrid itself

Question

I have a datagrid bound to a datatable , which has customized table style. I display the editable datagrid. I modify some rows ( say row 1, 5 and 6 ) on the datagrid from the interface. Now I would like to get this set of modified rows in the program. Somehow followoing methods are not working for me ? Method : 1 (objDRow.RowState = DataRowState.Modified) Dim objDRow As DataRow For Each objDRow In MyDataSet.Tables("MyTable").Rows If (objDRow.RowState = DataRowState.Modified) Then 'get value of that modified cell End If Next Method- 2 I tried to use dataview using Dim dview As New DataView(MyDataSet.Tables("MyTable")) dview.RowStateFilter = DataViewRowState.ModifiedOriginal And then iterating through each row of view, thinking that I get modified rows here..but does not wrok Method- 3 I tried to use following comarison objDRow.Item(2, DataRowVersion.Original) <> objDRow.Item(2, DataRowVersion.Current) not working. But surprisingly if you change the row value through code : it marks the row as modified row. for example objDRow.Item(2) = "xtz" <-------- i am changing the value here progrmmatically. Now if I do MsgBox(objDRow.RowState) then the state is modified ??? So the question is how do we detect mdofied rows ( or cells ) on datagrid rows when changes are made through visual interface, I mean directly from editing datagrid ?? Please if anyone knows let me know asap. Thanks.
