There are several way to accomplish this. One quick way is to create a data view instance out of the modified data table (data table after delete) and then call ToTable() method on that dataview. This will give us the original data.
DataView view= new DataView(yourTable, null, null, DataViewRowState.Deleted);
DataTable resultTable = view.ToTable();
Another approach would be
var rows=YourTable.Select(); // I assume your name of the table as YourTable and you can change it the way you want
foreach(var row in rows)
{
if (row.RowState == DataRowState.Deleted)
{
var splr_Cntctnm = (string)row["splr_Cntctnm", DataRowVersion.Original];
//you can access all deleted field information as above
}
}
